Description

The present invention relates to an ophthalmic device.

Conventionally, ophthalmic devices have been known that include a measurement head that performs measurements while observing an image of the anterior eye segment through an optical system, a drive mechanism that drives the measurement head up and down, left and right, and back and forth, and a monitor unit with a touch panel display screen that can display an image of the anterior eye segment (see, for example, Patent Document 1).

JP 2013-78524 A

In conventional devices, the monitor screen has a display area for the anterior eye image, etc., and a display area for operation buttons. The display area for operation buttons has a measurement mode button, an R button, and an L button. The measurement mode button is used to select the R/K measurement mode, the R button is used to select the right eye, and the L button is used to select the left eye. Note that the R/K measurement mode refers to the Refractive index (eyeball refraction)/Kerato (corneal curvature radius) measurement mode.

As such, when selecting a measurement mode, all you need to do is select the R/K measurement mode using the provided measurement mode button. Therefore, if you want to select a measurement item (Ref measurement only, Kerato measurement only, etc.), you must select the measurement item again on the measurement screen after selecting the measurement mode. This makes the operation to set the measurement mode and measurement items complicated, and there was an issue that the measurement mode and measurement items could not be easily set before or during measurement.

The present invention was developed in response to the above-mentioned issues, and aims to provide an ophthalmic device that allows users to easily set the measurement mode and measurement items before and during measurement.

To achieve the above object, the ophthalmologic apparatus of the present invention includes a measurement head, a drive mechanism, a monitor, and a control unit. The measurement head is positioned facing the subject's eye and performs measurements of multiple measurement items while observing an anterior eye image via an optical system. The drive mechanism drives the measurement head up, down, left, right, front, and back relative to the subject's eye. The monitor has a touch-panel display screen that has an anterior eye image display area that displays an anterior eye image and an operation button display area that displays operation buttons. The control unit controls each part of the device based on input information including touch operations on the display screen. When a mode button in the operation button display area is tapped, the control unit displays a measurement mode selection screen in the anterior eye image display area that displays all measurement modes and measurement items. The measurement mode and measurement items to be performed on the subject's eye are set by touching the display items on the measurement mode selection screen. The measurement mode selection screen displays individual setting buttons that allow individual setting of measurement items by tapping, and in addition to the individual setting buttons, it also displays area setting buttons that set measurement item areas for multiple measurement items.

In this way, before or during measurement, tapping the mode button displays the measurement mode selection screen, and touching the display items on the measurement mode selection screen sets the measurement mode and measurement items to be performed on the subject's eye. As a result, the measurement mode and measurement items can be easily set before or during measurement. Furthermore, in addition to being able to set measurement items individually, when a user wants to set a measurement item area for multiple measurement items, the user can do so by touching a button. Furthermore, when a user wants to delete some measurement item areas from a measurement item area for a combination of multiple measurement items, the user can delete them by touching a button. Therefore, the measurement mode and measurement items can be set freely and arbitrarily by touching the measurement mode selection screen while reducing the number of touch operations.

Below, we will explain the embodiments of the ophthalmic device according to the present invention based on Examples 1 to 3 shown in the drawings.

Example 1 is applied to an ophthalmic device 1 that has two measurement heads and combines measurements using two measurement items (REF, KRT) in the R/K measurement mode and measurements using two measurement items (TONO, PACHY) in the T/P measurement mode into a single device.

Here, "REF (abbreviation for Refractometer)" refers to the measurement of spherical refractive power, astigmatic refractive power, and astigmatic axis direction, hereinafter referred to as "REF measurement." "KRT (abbreviation for Keratometer)" refers to the measurement of corneal radius of curvature, corneal principal meridian direction, and corneal refractive power, hereinafter referred to as "keratometry." "TONO (abbreviation for Tonometer)" refers to the measurement of intraocular pressure, hereinafter referred to as "tonometry." "PACHY (abbreviation for Pachymeter)" refers to the measurement of corneal thickness, hereinafter referred to as "pachy measurement."

The ophthalmic device 1 of Example 1 is called an "autokeratorefractometer," and like the ophthalmic device 1 of Example 1, the ophthalmic devices of Examples 2 and 3 are also devices capable of obtaining measurement results for four types of measurement items from one eye. Note that throughout this specification, the X-axis, Y-axis, and Z-axis are defined as shown in each figure, with the left-right direction being the X-axis direction, the front-back direction being the Z-axis direction, and the up-down direction being the Y-axis direction.

First, the overall configuration of the ophthalmic device 1 according to Example 1 will be described with reference to Figures 1 to 5.

The ophthalmic device 1 comprises a device main body 10, a face support unit 20, and a monitor unit 40. The overall system for ophthalmic measurements also includes an optical table 30 on which the ophthalmic device 1 is placed, and a chair 50 on which the subject P sits. Each component is described in detail below.

As shown in Figures 1 to 3, the device main body 10 is placed on the top plate 31 of the optical table 30 and includes a base 11, a composite measurement head 12 (measurement head), and a cover member 13.

An XYZ drive mechanism and drive circuit 16 (drive mechanism) is provided inside the base unit 11 and between it and the composite measuring head 12. A control lever 111, a power switch 112, a power inlet 113, a USB input terminal 114, and a LAN output terminal 115 are provided on the outside of the base unit 11.

The XYZ drive mechanism/drive circuit 16 uses, for example, a stepping motor as a drive actuator, and drives the combined measurement head 12 in the XYZ directions (up/down, left/right, front/back) relative to the subject's eye E. The control lever 111 is an operating lever used when manually driving the combined measurement head 12 in the XYZ directions relative to the subject's eye E during alignment adjustment, etc. The power inlet 113 is used to plug in the power cord. The USB input terminal 114 can be connected to a barcode reader or the like via USB, allowing ID input, etc. The LAN output terminal 115 can be connected to an external device 60 via a connection cord 61, which will be described later.

As shown in FIG. 3, the combined measurement head 12 is positioned within a cover member 13 facing the subject's eye E, and performs measurements of multiple measurement items while observing an anterior ocular image via an optical system. The combined measurement head 12 has a T/P measurement head 12a (first measurement head) and an R/K measurement head 12b (second measurement head). The T/P measurement head 12a is composed of an optical system with an imaging element for an anterior ocular image, and performs tonoscopic and pachyscopic measurements for each of the subject P's left and right eyes. The R/K measurement head 12b is positioned below the T/P measurement head 12a, is composed of an optical system with an imaging element for an anterior ocular image, and performs reflex and keratoscopic measurements for each of the subject P's left and right eyes. Switching between T/P measurement mode and R/K measurement mode is performed by moving the combined measurement head 12 in the Y-axis direction, and switching between the left and right eyes is performed by moving the combined measurement head 12 in the X-axis direction.

The cover member 13 covers the combined measurement head 12. When the subject P side of the device main body 10 is the front side, the T/P measurement window 131 is located on the upper side of the front, and the R/K measurement window 132 is located below the T/P measurement window 131. A wide-angle camera 14 (see Figure 3) is located between the T/P measurement window 131 and the R/K measurement window 132. A printer cover 133 and a printer cover open button 134 are provided on the back side of the cover member 13. Furthermore, a measurement window height mark 135 for the R/K measurement window 132 is set on the side of the cover member 13 facing the subject P.

As shown in Figures 1 to 3, the face support unit 20 is connected and fixed to the front (front face) of the base unit 11 of the device main body unit 10, and functions to support the face of the subject P. The face support unit 20 includes a base unit 21, a chin rest unit 22, a pair of support posts 23, a forehead rest unit 24, a drive mechanism 25, and a chin rest paper stopper pin 28.

The chin rest 22 is movable up and down by a drive mechanism 25 (see Figure 4) relative to a base 21 that is fixedly connected to the base 11. A pair of support posts 23 protrude from both the left and right sides of the base 21, and the upper ends of the pair of support posts 23 are connected in the X-axis direction to form a forehead rest 24. A height mark 27 for the subject's eye E is set on the side of the support posts 23.

For example, as shown in Figure 3, subject P faces the ophthalmic device 1 while seated on the seating surface 51 of an elevating chair 50 placed in front of (in front of) the ophthalmic device 1, places their chin on the chin rest 22, and places their forehead against the forehead rest 24, while undergoing measurements of their eye characteristics. At this time, whether or not subject P's chin is resting is detected by a detection sensor 26 (see Figure 4), which will be described later.

As shown in Figure 3, the optical table 30 includes a top plate 31, a lifting mechanism 32, a table control unit 33, a power button 34, a lifting lever 35, and a caster base 36.

The lifting mechanism 32 raises and lowers the tabletop 31 under the control of the table control unit 33, which will be described later. The lifting mechanism 32 has a lifting rod 32a that supports the tabletop 31, a support rod 32b that supports the lifting rod 32a so that it can move up and down, and a drive unit 32c that moves the lifting rod 32a up and down. The caster base 36 is provided with casters 36a equipped with a locking mechanism.

As shown in Figures 1 to 3, the monitor unit 40 is attached to the top of the rear side of the cover member 13 and has a touch panel display screen 41. The monitor unit 40 includes the display screen 41, a monitor cover member 42, and a monitor support member 43.

The display screen 41 consists of a color LCD display and displays the anterior segment image, operation buttons, measurement status, etc. The monitor cover member 42 is a member that covers the outer periphery and back of the display screen 41, and as shown in Figure 3, the monitor cover member 42 houses control circuit units such as the main control unit 17. The monitor support member 43 is a member that mounts and supports the monitor unit 40 so that it can rotate freely around a horizontal axis (around the X-axis or Z-axis) and a vertical axis (around the Y-axis). This monitor support member 43 allows the display screen 41 of the monitor unit 40 to be positioned at a desired angle and direction depending on the examiner's position, posture, eye level, etc.

Next, the configuration of the control system in the ophthalmologic apparatus 1 according to Example 1 will be described with reference to Figure 4.

As shown in Figure 4, the control system of the ophthalmologic apparatus 1 includes a control system for the apparatus main body 10, a control system for the face support unit 20, and a control system for the optical table 30.

The control system of the device main body 10 includes a main control unit 17 (control unit), internal memory 17a, a storage unit 18, a measurement optical system 15, an XYZ drive mechanism and drive circuit 16, a monitor unit 40, a storage unit 18, an operation unit 19, and a wide-angle camera 14.

The control system for the face support unit 20 includes a drive mechanism 25 and a detection sensor 26. The control system for the optical table 30 includes a table control unit 33, an internal memory 33a, a lift lever 35, a power button 34, and a lift mechanism 32.

The main control unit 17 expands the programs stored in the storage unit 18 or internal memory 17a, for example, onto RAM, and performs overall control of each unit, including display control and operation control, of the ophthalmologic apparatus 1 in response to appropriate operation input signals from the operation unit 19. The main control unit 17 is connected to the drive mechanism 25 of the face support unit 20, the table control unit 33 of the optical table 30, and other components. An external device 60, such as a personal computer, is connected to the main control unit 17 via a connection cord 61 to a LAN output terminal 115 provided on the base unit 11 of the device main body 10. This configuration allows for information exchange, such as outputting data from the main control unit 17 to be stored in a database in the external device 60, and retrieving stored data from the database in the external device 60 in response to a request from the main control unit 17.

Operations on the operation unit 19 include touch operations such as tapping or long pressing on the display screen 41. The monitor unit 40 accepts operation inputs to the areas displayed on the display screen 41 and sends operation input signals to the main control unit 17. Operations on the operation unit 19 also include operations on the control lever 111. The wide-angle camera 14 captures a facial image, including both the left and right eyes, of the subject P, who is supported by the face support unit 20, from a single position on an imaging element.

Next, with reference to Figure 5, we will explain the basic display modes displayed on the display screen 41 of the monitor unit 40 from the preparation stage before measurement to the end of measurement.

As shown in Figure 5, the touch panel display screen 41 of the monitor unit 40 has an anterior eye image display area 411 that displays the anterior eye image Gf, an operation button display area 412 that displays operation buttons, and a measurement status display area 413 that displays measurement items.

The anterior eye image display area 411 is a rectangular area that is reduced in the vertical and horizontal directions from the overall area of the display screen 41. The anterior eye image display area 411 displays an anterior eye image Gf having a corneal bright spot image P1 as a measurement screen, and also displays a target area mark 40e and a minimum pupil diameter determination mark 40f at the center of the anterior eye image display area 411 as alignment marks.

In addition to the anterior eye image Gf, the anterior eye image display area 411 also displays the measurement results and number of measurements for each measurement item for each left and right eye. For example, when measuring using the R/K measurement mode, two measurement items, the reflex measurement result, the number of reflex measurements, the keratomileusis measurement result, and the number of keratomileusis measurements, are displayed for each left and right eye. In addition, the anterior eye image display area 411 also displays the corneal vertex distance VD.

The operation button display area 412 is a strip-shaped area defined by the top, left, and right sides of the four outer periphery of the entire area of the display screen 41 excluding the anterior eye image display area 411.

The upper edge of the operation button display area 412 is equipped with a mode button 1B, an RK mode display/setting button 2B, a TP mode display/setting button 3B, a subject ID button 4B, and an examiner ID button 5B.

Mode button 1B is located in the center of the top edge of the operation button display area 412, and when tapped, displays the first measurement mode selection screen 71, which will be described later. RK mode display/setting button 2B and TP mode display/setting button 3B are located to the left and right of mode button 1B. RK mode display/setting button 2B displays R/K measurement mode and switches to R/K measurement mode when the button is touched. TP mode display/setting button 3B displays T/P measurement mode and switches to T/P measurement mode when the button is touched. Mode button 1B, RK mode display/setting button 2B, and TP mode display/setting button 3B form a triple mode button.

The subject ID button 4B is located to the left of the RK mode display/setting button 2B; tap it to enter the subject ID. The examiner ID button 5B is located to the right of the TP mode display/setting button 3B; tap it to enter the examiner ID.

On the left side of the operation button display area 412, from top to bottom, are arranged the R button 6B, the clear all measurement values button 7B, the display all data button 8B, the end button 9B, the air check button 10B, the alignment stop button 11B, the chin rest up/down movement button 12B, and the print button 13B.

Tapping the R button 6B selects the right eye. Tapping the Clear All Measurements button 7B clears all measurement data. Tapping the Display All Data button 8B displays all measurement data. Tapping the End button 9B moves the chin rest 22 and combined measuring head 12 to the end position. Tapping the Air Check button 10B performs an air check. The Alignment Stop button 11B is displayed during measurement and stops alignment or measurement when tapped. Tapping the Chin Rest Up/Down Movement button 12B moves the chin rest 22 up and down. Tapping the Print button 13B prints out the measurement results.

On the right side of the operation button display area 412, from top to bottom, are arranged the L button 14B, setup button 15B, cataract button 16B, corneal diameter button 17B, FOG button 18B, fixation target button 19B, start button 20B, measurement head forward/backward button 21B, and auto/manual button 22B.

Tapping the L button 14B selects the left eye. Tapping the setup button 15B opens the setup screen. Tapping the cataract button 16B is used when measurement cannot be performed normally due to cataracts, eyelids, eyelashes, blinking, etc. Tapping the corneal diameter button 17B switches to corneal diameter measurement mode. Tapping the FOG button 18B switches between FOG mode for the first measurement only or for each measurement during continuous measurement. Tapping the fixation target button 19B changes the brightness of the fixation target. Tapping the start button 20B starts measurement. Tapping the measurement head advance/retract button 21B moves the combined measurement head 12 toward/away from the subject's eye E. Tapping the auto/manual button 22B switches between auto mode and manual mode for ophthalmic measurement.

The measurement status display section 413 is located on the bottom side of the operation button display area 412 and displays the measurement status as an icon. The icon display consists of eight measurement icons arranged from left to right. The eight measurement icons are: right eye keratomileusis measurement icon Ia, right eye reflex measurement icon Ib, left eye keratomileusis measurement icon Ic, left eye reflex measurement icon Id, left eye pachymetry measurement icon Ie, left eye tonometry measurement icon If, right eye pachymetry measurement icon Ig, and right eye tonometry measurement icon Ih. The arrangement of these eight measurement icons corresponds to the standard measurement order for each measurement item when performing continuous measurements using all measurement items. Note that the measurement status display is not limited to an icon display using the display items as icons, and may also be in English, simplified English, or other formats.

When the measurement mode and measurement items to be performed on the subject's eye E are set, the main control unit 17 displays the set measurement mode and measurement items in the measurement status display unit 413 so that they can be seen. For example, when all measurement modes and measurement items are set, all icons in the measurement status display unit 413 are lit. When some measurement modes and measurement items are set, some of the set icons are lit. Furthermore, during a measurement when multiple measurement items are set, the overall display brightness may be changed, the underscore may be brightened, or parentheses or marks may be added to the icons so that the measurement items being measured can be distinguished from those not being measured.

Next, the setting of the measurement mode, measurement items, and eye to be measured by touch operation on the ophthalmologic apparatus 1 according to Example 1 will be described with reference to Figures 6 to 8.

After turning on the power switch 112, tap the mode button 1B located in the center of the top edge of the operation button display area 412, as shown in Figure 6. This tap operation displays the first measurement mode selection screen 71 (Figure 7), which displays the measurement mode and measurement items all at once, superimposed on the anterior eye image display area 411 of the display screen 41.

As shown in FIG. 7, the first measurement mode selection screen 71 has right eye individual selection buttons: a right eye reflex measurement button 81RB, a right eye keratoconstriction measurement button 82RB, a right eye tonoconstriction measurement button 83RB, and a right eye pachymetry measurement button 84RB. Left eye individual selection buttons: a left eye reflex measurement button 81LB, a left eye keratoconstriction measurement button 82LB, a left eye tonoconstriction measurement button 83LB, and a left eye pachymetry measurement button 84LB. Left and right eye region setting buttons: a right eye setting button 85RB and a left eye setting button 85LB. Measurement mode region setting buttons: an all measurement mode setting button 86AB, an R/K measurement mode setting button 86KB, and a T/P measurement mode setting button 86PB. Other buttons include a set button 87B, a clear button 88B, and a close screen button 89B.

To select all measurement items by touching the first measurement mode selection screen 71, press the all measurement mode setting button 86AB. This touch operation causes all measurement buttons and setting buttons, including the all measurement mode setting button 86AB, to be displayed with a lit circle, as shown in Figure 8A, and all measurement items are selected.

When selecting a right eye measurement item by touch operation on the first measurement mode selection screen 71, press the right eye setting button 85RB. This touch operation causes the measurement items in the right eye measurement mode, including the right eye setting button 85RB, to be displayed with a lit circle, as shown in FIG. 8B, and the right eye measurement item area is selected. Note that when selecting a left eye measurement item by touch operation on the first measurement mode selection screen 71, pressing the left eye setting button 85LB similarly selects the left eye measurement item area.

When selecting the R/K measurement mode for the left and right eyes by touching the first measurement mode selection screen 71, press the R/K measurement mode setting button 86KB. This touch operation causes the measurement items in the R/K measurement mode for the left and right eyes, including the R/K measurement mode setting button 86KB, to be displayed with a circular frame lit, as shown in FIG. 8C, and the R/K measurement mode area is selected. When selecting the T/P measurement mode for the left and right eyes by touching the first measurement mode selection screen 71, press the T/P measurement mode setting button 86PB, and the T/P measurement mode area is similarly selected.

When selecting the R/K measurement mode for the right eye by touching the first measurement mode selection screen 71, press the R/K measurement mode setting button 86KB to select the R/K measurement mode for both the left and right eyes. Next, when the left eye setting button 85LB is pressed, the measurement items for the left eye are blacked out and deleted by this touch operation. As shown in Figure 8D, the remaining measurement items are displayed with a lit circle, and the R/K measurement mode area for the right eye is selected. Note that when selecting the R/K measurement mode for the left eye by touching the first measurement mode selection screen 71, press the right eye setting button 85RB. Furthermore, when selecting the T/P measurement mode for one of the left or right eyes, the area can be set by similar touching.

When you have confirmed the settings for individual measurement items or area measurements using the above tap operations, press the set button 87B to confirm the settings. If you want to cancel or change the settings, press the clear button 88B to clear the current settings. Furthermore, when you have finished setting the individual measurement items or area measurements, press the close screen button 89B to close the first measurement mode selection screen 71.

As described above, in the ophthalmologic apparatus 1 according to Example 1, the measurement mode, measurement items, and measurement eye can be freely set as desired by touching the first measurement mode selection screen 71, which is displayed by tapping the mode button 1B.

Next, with reference to Figures 9 and 10, we will explain how to set the measurement mode, measurement items, and eye to be measured in cooperation with the database in the ophthalmologic apparatus 1 of Example 1.

The main control unit 17 of the ophthalmic apparatus 1 according to Example 1 is capable of linking with the database of the external device 60. Therefore, the measurement mode, measurement items, and measurement eye are set for the eye E of a specific subject P, and when the ophthalmic measurement is completed according to the settings, the setting history for the measurement mode, measurement items, and measurement eye linked to the specific subject P is stored. At this time, the setting history is stored in the database of the linked external device 60 so that it can be called up as a data list 100 (Figure 9) including the specific subject P.

Therefore, when a specific subject P is to undergo ophthalmic measurement at a follow-up visit, as shown in FIG. 9, the database of the external device 60 is called up and a data list 100 is displayed on the screen of the external device 60. The specific subject P due for the follow-up visit is then selected from the many data lists 100 displayed. By reading information about the subject P that has already been saved through the selection operation of the subject P, the subject P's ID, measurement mode, measurement items, and measurement eye are all set at once.

In other words, if subject P is undergoing ophthalmic measurement on a follow-up visit and there are no changes to the measurement mode, measurement items, or eye to be measured, there is no need to set the measurement mode, measurement items, or eye to be measured on the first measurement mode selection screen 71 displayed by tapping mode button 1B. For example, in the case of a follow-up subject P who only needs to have his or her right eye measured, simply selecting subject P on a follow-up visit from the data list 100 displays the first measurement mode selection screen 71 with the measurement mode, measurement items, and eye to be measured already set. In other words, as shown in FIG. 10, the first measurement mode selection screen 71 displays the settings with the right eye measurement item area selected, just as when the right eye setting button 85RB is touched.

Here, we have explained an example of calling up a database from the external device 60. However, it is also possible to call up a database stored in the memory unit 18 of the device main body 10 and select a specific subject P. In this case, when the ophthalmic measurement is completed, the measurement mode, measurement items, and setting history for the eye being measured are stored in the database of the memory unit 18 of the device main body 10 as a data list linked to the specific subject P.

As described above, the ophthalmologic apparatus 1 according to Example 1 provides the following advantages.

(1) The ophthalmic device 1 includes a composite measurement head 12 (measurement head), an XYZ drive mechanism and drive circuit 16 (drive mechanism), a monitor unit 40, and a main control unit 17 (control unit). The composite measurement head 12 is positioned facing the subject's eye E and measures multiple measurement items while observing an anterior eye image Gf via an optical system. The XYZ drive mechanism and drive circuit 16 drives the composite measurement head 12 up, down, left, right, front, and back relative to the subject's eye E. The monitor unit 40 has a touch-panel display screen 41 that includes an anterior eye image display area 411 that displays the anterior eye image Gf and an operation button display area 412 that displays operation buttons. The main control unit 17 controls each unit of the device based on input information, including touch operations on the display screen 41. When the mode button 1B in the operation button display area 412 is tapped, the main control unit 17 displays a first measurement mode selection screen 71 in the anterior eye image display area 411, which collectively displays the measurement mode and measurement items. By touching the display items on the first measurement mode selection screen 71, the measurement mode and measurement items to be performed on the subject's eye E are set.

That is, before or during measurement, tapping the mode button 1B displays the first measurement mode selection screen 71, and by touching the display items on the first measurement mode selection screen 71, the measurement mode and measurement items to be performed on the subject's eye E are set. This makes it easy to set the measurement mode and measurement items before or during measurement.

(2) The monitor unit 40 has a measurement status display unit 413 that displays the measurement status on the display screen 41. When the measurement mode and measurement items to be performed on the subject's eye E are set, the main control unit 17 displays the set measurement mode and measurement items on the measurement status display unit 413.

In other words, once the measurement mode and measurement items to be performed on the subject's eye E are set, the set measurement mode and measurement items are displayed on the measurement status display unit 413. Therefore, once the measurement mode and measurement items are set, the set measurement status (measurement mode, measurement items) can be recognized at a glance by looking at the display screen 41 of the monitor unit 40.

(3) The main control unit 17 displays a right eye setting button 85RB for setting the right eye of the subject's eye E and a left eye setting button 85LB for setting the left eye of the subject's eye E on the first measurement mode selection screen 71.

In other words, the first measurement mode selection screen 71 displays the display items for setting the measurement mode and measurement items, plus the right eye setting button 85RB and left eye setting button 85LB, all together as display items. Therefore, the first measurement mode selection screen 71 allows you to set the measurement mode, measurement items, and the eye to be measured all at once.

(4) The main control unit 17 displays individual setting buttons (measurement buttons 81RB, 82RB, 83RB, 84RB, 81LB, 82LB, 83LB, 84LB) on the first measurement mode selection screen 71 for individually setting measurement items by tapping. In addition to displaying the individual setting buttons, it also displays area setting buttons (right eye setting button 85RB, left eye setting button 85LB, all measurement mode setting button 86AB, R/K measurement mode setting button 86KB, T/P measurement mode setting button 86PB) for setting measurement item areas for multiple measurement items.

In other words, in addition to being able to set measurement items individually, when you want to set a measurement item area for multiple measurement items, you can do so by touching a button. Also, when you want to delete some measurement item areas from a measurement item area for a combination of multiple measurement items, you can delete them by touching a button. Therefore, you can freely set the measurement mode and measurement items by touching the first measurement mode selection screen 71 while reducing the number of touch operations.

(5) After the main control unit 17 sets the measurement mode and measurement items to be performed on the subject's eye E and completes the ophthalmic measurement, it stores the measurement mode, measurement items, and setting history for the subject's eye in the data list 100 for the subject P stored in the linked database.

In other words, when ophthalmic measurement for subject P is completed, the setting history for the measurement mode, measurement items, and eye to be measured is stored in the data list for subject P held in the linked database. Therefore, when subject P returns for a follow-up visit, the stored setting history for the measurement mode, measurement items, and eye to be measured can be referenced to perform setting operations for the measurement mode, measurement items, and eye to be measured. In addition, by utilizing the stored setting history, the measurement mode, measurement items, and eye to be measured can be set all at once by subject P's selection during a follow-up visit.

(6) When subject P is returning for a follow-up examination, the main control unit 17 displays the data list 100 stored in the linked database, and sets the measurement mode, measurement items, and measurement eye by selecting the returning subject P from the data list 100.

In other words, when a patient returns for a follow-up visit, the stored setting history is utilized, and the measurement mode, measurement items, and measurement eye are set simply by the patient P performing a selection operation. Therefore, when patient P returns for a follow-up visit, the measurement mode, measurement items, and measurement eye can be set easily and quickly.

Example 2 is an example in which the display format displayed on the display screen 41 of the monitor unit 40 from the pre-measurement preparation stage to the end of measurement and the display format of the measurement mode selection screen are different from those in Example 1.

First, referring to Figure 11, we will explain the basic display format displayed on the display screen 41 of the monitor unit 40 from the preparation stage before measurement to the end of measurement.

As shown in FIG. 11, the touch panel display screen 41 of the monitor unit 40 has an anterior eye image display area 411 that displays the anterior eye image Gf, an operation button display area 412 that displays operation buttons, and a measurement status display area 413 that displays measurement items.

As in Example 1, the anterior eye image display area 411 is an area with a rectangular area that is reduced in the vertical and horizontal directions from the overall area of the display screen 41. As in Example 1, the anterior eye image display area 411 displays the anterior eye image Gf having the corneal bright spot image P1, and also displays the target area mark 40e and the minimum pupil diameter determination mark 40f at the center of the anterior eye image display area 411. As in Example 1, the anterior eye image display area 411 displays the measurement results and number of measurements for each of the left and right eyes in addition to the anterior eye image Gf.

The operation button display area 412 is a strip-shaped area defined by the top, bottom, right, and upper left sides of the four outer edges of the display screen 41 excluding the anterior eye image display area 411 from the overall area of the display screen 41.

The upper edge of the operation button display area 412 is arranged with a mode button 1B, an RK mode display/setting button 2B, a TP mode display/setting button 3B, a subject ID button 4B, and an examiner ID button 5B. Here, the mode button 1B, the RK mode display/setting button 2B, and the TP mode display/setting button 3B form a triple mode button, similar to Example 1.

The upper left side of the operation button display area 412 is arranged with, from top to bottom, the R button 6B, the chin rest up/down movement button 12B, and the end button 9B.

On the right side of the operation button display area 412, from top to bottom, are arranged the L button 14B, the measurement head forward/backward button 21B, the start button 20B, and the auto/manual button 22B.

At the bottom of the operation button display area 412, from left to right, there are a cataract button 16B, a fixation target button 19B, a FOG button 18B, a display all data button 8B, a print button 13B, a corneal diameter button 17B, and a clear all measurement values button 7B.

The measurement status display section 413 is located at the bottom left side of the operation button display area 412 and displays the measurement status in simple English characters. The simple English character display section has a measurement mode display section MA, a first measurement item display section IA, and a second measurement item display section IB. The measurement mode display section MA displays "R/K" indicating R/K measurement mode, or "T/P" indicating T/P measurement mode. The first measurement item display section IA displays "KRT" indicating keratometry measurement, or "TONO" indicating tonometry measurement. The second measurement item display section IB displays "REF" indicating refometry measurement, or "PACHY" indicating pachymetry measurement.

Next, the setting of the measurement mode, measurement items, and eye to be measured by touch operation in the ophthalmologic apparatus 1 according to Example 2 will be described with reference to Figures 12 to 14.

After turning on the power switch 112, tap the mode button 1B, which is located in the center of the top edge of the operation button display area 412. When this tapping operation is performed, as shown in Figure 12, a second measurement mode selection screen 72 is displayed, which displays the measurement mode and measurement items all at once, superimposed on the anterior eye image display area 411 of the display screen 41.

As shown in FIG. 13, the second measurement mode selection screen 72 has individual selection buttons: a REF measurement button 91B and a KERAT measurement button 92B in the R/K measurement mode, and a TON measurement button 93B and a PAC measurement button 94B in the T/P measurement mode. Other buttons include an OK button 95B and a CANCEL button 96B.

In Example 1, the first measurement mode selection screen 71 was shown in a format that integrated the settings of the measurement mode, measurement items, and eye to be measured, but in Example 2, the settings of the measurement mode and measurement items are separated from the settings of the eye to be measured. The reasons for this are, firstly, that by setting the measurement mode and measurement items for each eye while observing the condition of the subject P, the examiner can perform the measurement while concentrating on the subject P. Secondly, in facilities where the measurement items rarely differ between the two eyes, being able to set only the measurement mode and measurement items will not interfere with normal medical treatment.

Setting the measurement mode and measurement items is performed by the REF measurement button 91B, KERAT measurement button 92B, TON measurement button 93B, PACIFIC measurement button 94B, RK mode display/setting button 2B, and TP mode display/setting button 3B.

Setting the eye to be measured is shared between the R button 6B and the L button 14B. When setting both the left and right eyes, the R button 6B and L button 14B are displayed without a lock icon, as shown in Figure 14A. On the other hand, when setting only one eye, for example the left eye, the lock icon IK is displayed partially overlapping the R button 6B by lock icon processing, and the L button 14B is displayed without a lock icon, as shown in Figure 14B.

Next, we will explain the measurement status display function when setting operation cases #1 to #4 are selected on the second measurement mode selection screen 72, with reference to Figures 15A to 15D.

Setting the REF measurement button 91B and KERAT measurement button 92B for the R/K measurement mode on the second measurement mode selection screen 72 by touch operation is considered setting operation case #1. In setting operation case #1, as shown in FIG. 15A, "RK" is displayed on the RK mode display/setting button 2B, and "R/K" is displayed on the measurement mode display area MA of the measurement status display unit 413. This display on the display screen 41 allows visual confirmation that the R/K measurement mode (REF measurement, KERAT measurement) has been set.

Setting operation case #2 occurs when only the REF measurement button 91B in the R/K measurement mode is set by touch operation on the second measurement mode selection screen 72. In setting operation case #2, as shown in FIG. 15B, "RK" is displayed on the RK mode display/setting button 2B, and "REF" is displayed on the second measurement item display section IB of the measurement status display section 413. This display on the display screen 41 allows visual confirmation that REF measurement in the R/K measurement mode has been set.

If you want to set only the REF measurement in the R/K measurement mode, touch the RK mode display/setting button 2B and the second measurement item display section IB. By touching buttons that are not on the second measurement mode selection screen 72, you can also perform temporary manual settings without opening the second measurement mode selection screen 72.

Setting operation case #3 occurs when the second measurement mode selection screen 72 is set by touching the reflex measurement button 91B in R/K measurement mode and the tono measurement button 93B in T/P measurement mode. In setting operation case #3, as shown in FIG. 15C, during measurement in R/K measurement mode, "RK" is displayed on the RK mode display/setting button 2B, and "REF" is displayed on the second measurement item display section IB of the measurement status display section 413. When R/K measurement mode ends and transitions to T/P measurement mode, the measurement status display section 413 switches to display T/P measurement mode, and "TONO" is displayed on the first measurement item display section IA. This display on the display screen 41 allows visual confirmation that the setting is to transition from reflex measurement in R/K measurement mode to tono measurement in T/P measurement mode.

Setting the Tono Measurement button 93B and Pachy Measurement button 94B for the T/P measurement mode by touching the second measurement mode selection screen 72 is considered setting operation case #4. In setting operation case #4, as shown in FIG. 15D, "TP" is displayed on the TP mode display/setting button 3B, and "T/P" is displayed on the measurement mode display area MA of the measurement status display unit 413. This display on the display screen 41 allows visual confirmation that the T/P measurement mode (tono measurement, pachy measurement) has been set.

Next, we will explain how a long press transitions to a non-selected T/P measurement mode, with reference to Figures 16A and 16B.

In setting operation case #1 (upper left of Figure 16A), "RK" is displayed on the RK mode display/setting button 2B, and "R/K" is displayed on the measurement mode display area MA of the measurement status display unit 413 (lower left of Figure 16A). When not measuring in R/K measurement mode, pressing and holding the TP mode display/setting button 3B (lower center of Figure 16A) switches the measurement head from the R/K measurement head 12b to the T/P measurement head 12a.

By switching the measurement head, the button that is lit changes from the RK mode display/setting button 2B to the TP mode display/setting button 3B. At the same time, the display in the measurement status display unit 413 also changes from R/K measurement mode to T/P measurement mode, and "T/P" is displayed lit in the measurement mode display unit MA (lower right part of Figure 16A).

Therefore, if you tap the mode button 1B during measurement, the second measurement mode selection screen 72 will be displayed (top right of Figure 16A). On the second measurement mode selection screen 72, the REF measurement button 91B and KERAT measurement button 92B for the R/K measurement mode, and the TON measurement button 93B and PAC measurement button 94B for the T/P measurement mode will be lit.

In setting operation case #2 (upper left of Figure 16B), "RK" is displayed on the RK mode display/setting button 2B, and "REF" is displayed on the second measurement item display section IB of the measurement status display section 413 (lower left of Figure 16B). When not measuring in R/K measurement mode, pressing and holding the TP mode display/setting button 3B (lower center of Figure 16B) switches the measurement head from the R/K measurement head 12b to the T/P measurement head 12a.

By switching the measurement head, the button that is lit changes from the RK mode display/setting button 2B to the TP mode display/setting button 3B. At the same time, the display in the measurement status display unit 413 also changes from R/K measurement mode to T/P measurement mode, and "T/P" is displayed lit in the measurement mode display unit MA (lower right part of Figure 16B).

Therefore, if you tap the mode button 1B during measurement, the second measurement mode selection screen 72 will be displayed (top right of Figure 16B). On the second measurement mode selection screen 72, only the reflex measurement button 91B for the R/K measurement mode and the tono measurement button 93B and pachy measurement button 94B for the T/P measurement mode will be lit.

As described above, the ophthalmic device 1 of Example 2 provides the following effects in addition to the effects (1), (2), (5), and (6) above.

(7) The composite measurement head 12 includes a T/P measurement head 12a used in the T/P measurement mode and an R/K measurement head 12b used in the R/K measurement mode. The monitor unit 40 has a TP mode display/setting button 3B for displaying/setting the T/P measurement mode and an RK mode display/setting button 2B for displaying/setting the R/K measurement mode in the operation button display area 412. When one of the T/P measurement mode and the R/K measurement mode is not set, the main control unit 17 switches the measurement head and transitions to the measurement mode that is not set by pressing and holding the other measurement mode display/setting button.

For example, when not performing a measurement in the set R/K measurement mode, pressing and holding the unset TP mode display/setting button 3B switches the composite measurement head 12 to the T/P measurement head 12a and transitions to the unset T/P measurement mode. Therefore, when you want to transition to an unset measurement mode mid-measurement, you can simply press and hold one button, eliminating the need to set the second measurement mode selection screen 72 that is displayed by tapping the mode button 1B.

Example 3 is an example in which at least one of the measurement order and the number of measurements can be set when setting measurement items on the measurement mode selection screen.

Next, with reference to Figures 17 to 19, the setting operation of the measurement mode, measurement item, measurement eye, measurement order, and number of measurements by tapping on the ophthalmologic device 1 according to Example 3 will be described.

After turning on the power switch 112, tap the mode button 1B located in the center of the top edge of the operation button display area 412. When this tapping operation is performed, as shown in Figure 12, a third measurement mode selection screen 73 is displayed, superimposed on the anterior eye image display area 411 of the display screen 41, and displaying the measurement mode and measurement items all at once.

As shown in Figure 17, the third measurement mode selection screen 73 has an R button 6B as the right eye selection button and an L button 14B as the left eye selection button. It also has individual selection buttons for the left and right eyes: a Reflex measurement button 91B and a Kerato measurement button 92B in the R/K measurement mode, and a Tono measurement button 93B and a Pachy measurement button 94B in the T/P measurement mode. Furthermore, each of the four measurement buttons has a number setting button 97B for the right eye and a number setting button 98B for the left eye. Other buttons include an OK button 95B and a Cancel button 96B.

To set the measurement mode, touch the Reflex Measurement button 91B and the Kerato Measurement button 92B for both eyes or one eye to set the R/K measurement mode. Touch the Tono Measurement button 93B and the Pachy Measurement button 94B for both eyes or one eye to set the T/P measurement mode.

To set the measurement items, touching only the Reflex Measurement button 91B or the Kerato Measurement button 92B for both eyes or one eye will set only one measurement item in R/K measurement mode. Also, touching only the Tono Measurement button 93B or Pachy Measurement button 94B for both eyes or one eye will set only one measurement item in T/P measurement mode.

To set the eye to be measured, if both eyes are being set, tap both the R button 6B and the L button 14B. If one eye is being set, tap either the R button 6B or the L button 14B for the eye you want to set.

The measurement order is set by tapping the number setting buttons 97B, 98B, for example, by tapping the eight number setting buttons 97B, 98B, as shown in Figure 18. In the example shown in Figure 18, number 1 is the right kerato measurement, number 2 is the right reflex measurement, number 3 is the right pachy measurement, number 4 is the right tono measurement, number 5 is the left kerato measurement, number 6 is the left reflex measurement, number 7 is the left pachy measurement, and number 8 is the left tono measurement.

The number of measurements is set by tapping the eight number setting buttons 97B and 98B, for example, as shown in Figure 19. In the example shown in Figure 19, the right keratoconstrictor measurement is performed three times, the right reflex measurement is performed three times, the right pachymetry measurement is performed twice, the right tonoconstrictor measurement is performed once, the left keratoconstrictor measurement is performed three times, the left reflex measurement is performed three times, the left pachymetry measurement is performed twice, and the left tonoconstrictor measurement is performed once.

Here, the measurement order and number of measurements may be set either alone or both. If both are set, for example, the third measurement mode selection screen 73 can be switched between the measurement order setting mode screen and the number of measurements setting mode screen.

As described above, the ophthalmologic apparatus 1 of Example 3 provides the following advantages in addition to the advantages (1) to (7) described above.

(8) The main control unit 17 configures the third measurement mode selection screen 73, which is displayed when setting the measurement mode and measurement items, as a display screen that allows the measurement order of the measurement items to be set. Therefore, by operating the third measurement mode selection screen 73, the measurement order when measuring multiple measurement items consecutively can be set.

(9) The main control unit 17 configures the third measurement mode selection screen 73, which is displayed when setting the measurement mode and measurement items, as a display screen that allows the number of measurements for each measurement item to be set. Therefore, by operating the third measurement mode selection screen 73, the number of measurements for each measurement item can be set when measuring multiple measurement items.

The ophthalmic device of the present invention has been described above based on Examples 1 to 3. However, the specific configuration is not limited to these examples. Design changes and additions are permitted as long as they do not deviate from the gist of the invention as defined in each claim.

In Examples 1 to 3, an example of an ophthalmic device 1 equipped with a composite measurement head 12 using a T/P measurement head 12a (first measurement head) and an R/K measurement head 12b (second measurement head) was shown. However, the measurement head is not limited to the composite measurement head used in Examples 1 to 3, and may be any measurement head that has multiple measurement modes and multiple measurement items, and in which the measurement mode and measurement items can be changed before or during measurement. In addition to the T/P measurement head and R/K measurement head, various ocular characteristic measurement heads for the subject eye may also be used, such as a corneal shape measurement head, fundus photography head, axial length measurement head, endothelial cell measurement head, etc.

In Example 1, an example of a first measurement mode selection screen 71 was shown as the measurement mode selection screen, on which the measurement mode, measurement items, and measurement eye settings can be freely set by touching a button. In Example 2, an example of a second measurement mode selection screen 72 was shown as the measurement mode selection screen, on which the measurement mode and measurement item settings are separated from the measurement eye settings. In Example 3, an example of a third measurement mode selection screen 73 was shown as the measurement mode selection screen, on which at least one of the measurement order and the number of measurements can be set. However, the measurement mode selection screen is not limited to these examples, and measurement mode selection screens with various changes in display format may also be used. For example, as shown in Figure 20, a fourth measurement mode selection screen 74 may be used, on which the measurement mode, measurement items, and measurement eye can be selected one by one. Note that the symbols in Figure 20 are the same as those used in the first measurement mode selection screen 71.

In Examples 1 to 3, the mode button is tapped to display the measurement mode selection screen, and the measurement mode and measurement items to be performed on the subject's eye are set by touching the display items on the measurement mode selection screen. Once the measurement mode and measurement items are set, the set measurement mode and measurement items are displayed in the measurement status display. However, a memory call function may be added to Examples 1 to 3 for the display of the measurement mode selection screen or the measurement status display, so that the display changes to the set display by automatic call depending on the day of the week or date and time, or by simply performing a call operation. Here, the "memory call function" refers to a function that stores the measurement mode and measurement items to be performed for a specific prescription when they are set, and then automatically calls them or displays the memorized measurement mode and measurement items from the next time. For example, if the day of the week and date and time for measurement are specified for a prescription by a glaucoma specialist, eyeglass prescription, contact lens prescription, etc., the day of the week and date and time can be stored along with the settings, and an automatic call is used to automatically call the settings when the memorized day of the week and date and time arrive. Additionally, for example, if a standard basic eyeglass prescription does not have a specific day or date for measurement, a call operation is used to recall stored settings using a button or other means. This memory call function eliminates the need to go to the setup screen each time a measurement starts and press multiple buttons to select measurement items one by one from the initial settings, reducing the operational burden on the examiner.

In Examples 1 to 3, the display screen 41 of the monitor unit 40 attached to the device main body 10 serves as the operation unit 19, and an example of an ophthalmic device 1 in which the subject P and the examiner perform measurements while facing each other in close proximity is shown. However, the operation unit may be, for example, a detachable monitor unit, which the examiner can carry and remotely operate from a separate room. Furthermore, an external device such as a personal computer with a touch panel display screen, a tablet terminal, a smartphone, or other information terminal or dedicated terminal may serve as the monitor unit, separate from the monitor unit attached to the device main body, and connected to the device main body via wireless communication. In this case, by installing the external device as the monitor unit in a desired location away from the ophthalmic device, ophthalmic measurements can be performed remotely while visually checking the subject's condition from the remote location where the external device is installed.
