Summary of the Invention

Problems to be Solved by the Invention

[0004] In the conventional apparatus, a display area for an anterior eye image and the like and a display area for operation buttons are provided on the display screen of the monitor unit. The display area for the 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. The R / K measurement mode refers to a ref (ocular refractive power) / kerat (corneal radius of curvature) measurement mode.

[0005] As described above, when selecting the measurement mode, only the R / K measurement mode can be selected by the prepared measurement mode button. Therefore, when it is desired to select a measurement item (only ref measurement, only kerat measurement, etc.), it is necessary to select the measurement item again on the measurement screen or the like after selecting the measurement mode. For this reason, there is a problem that the setting operations for the measurement mode and the measurement item become complicated, and the measurement mode and the measurement item cannot be easily set before or during the measurement.

[0006] This invention has been made in view of the above-mentioned problems, and aims to provide an ophthalmic device that allows for easy setting of the measurement mode and measurement items before and during measurement. [Means for solving the problem]

[0007] To achieve the above objective, the ophthalmic apparatus of the present invention comprises a measuring head, a drive mechanism, a monitor unit, and a control unit. The measuring head is positioned opposite the eye under examination and measures multiple measurement items while observing the anterior segment image via an optical system. The drive mechanism drives the measuring head. The monitor unit has a touch panel display screen. The control unit controls each part of the apparatus based on input information, including touch operations on the display screen. The display screen is configured with an anterior segment image display area for displaying the anterior segment image, an operation button display area for displaying operation buttons, and a measurement status display unit for displaying the measurement items. The operation button display area includes a mode button, a right eye selection button, a left eye selection button, a start button, a print button, and a setup button. The measurement status display unit displays multiple icons indicating the measurement status for each measurement item. When the measurement items to be performed on the eye under examination are set, the control unit lights up multiple icons according to the set status. The multiple icons displayed on the measurement status display unit are configured to show the measurement item being measured with greater visibility than the measurement item not being measured during a measurement in which multiple measurement items are set. [Effects of the Invention]

[0008] In this way, before or during measurement, tapping the mode button displays the measurement mode selection screen, and by touching the displayed items on the measurement mode selection screen, the measurement mode and measurement items to be performed on the eye being examined are set. As a result, the measurement mode and measurement items can be easily set before or during measurement. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments for carrying out the ophthalmic device according to the present invention will be described based on Examples 1 to 3 shown in the drawings.

Examples

[0011] Example 1 applies to an ophthalmic device 1 equipped with two measuring heads, which integrates measurements of two items (REF, KRT) using the R / K measurement mode and measurements of two items (TONO, PACHY) using the T / P measurement mode into a single unit.

[0012] Here, "REF (abbreviation for Refractometer)" refers to the measurement of spherical refractive power, astigmatic refractive power, and astigmatic axis direction, and will be referred to as "REF measurement" below. "KRT (abbreviation for Keratometer)" refers to the measurement of corneal curvature radius, corneal principal meridian direction, and corneal refractive power, and will be referred to as "Keratometer measurement" below. "TONO (abbreviation for Tonometer)" refers to intraocular pressure measurement, and will be referred to as "Tonometer measurement" below. "PACHY (abbreviation for Pachymeter)" refers to corneal thickness measurement, and will be referred to as "Pachymeter measurement" below.

[0013] The ophthalmic device 1 in Example 1 is called an "autokeratrefractonometer," and the ophthalmic devices in Examples 2 and 3 are similar to the ophthalmic device 1 in Example 1, capable of acquiring measurement results for four types of measurement items in one eye. Throughout this specification, the X, Y, and Z axes are used 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 for the purposes of the description in this specification.

[0014] First, the overall configuration of the ophthalmic device 1 according to Example 1 will be explained with reference to Figures 1 to 5.

[0015] The ophthalmic device 1 comprises a main unit 10, a face support unit 20, and a monitor unit 40. The complete system for ophthalmic measurement includes an optical table 30 on which the ophthalmic device 1 is placed, and a chair 50 on which the subject P sits. Details of each component are described below.

[0016] As shown in Figures 1 to 3, the main body of the device 10 is placed on the top plate 31 of the optical table 30 and comprises a base 11, a composite measuring head 12 (measuring head), and a cover member 13.

[0017] Inside the base unit 11, an XYZ drive mechanism / drive circuit 16 (drive mechanism) is provided between it and the composite measuring head 12. Outside the base unit 11, 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.

[0018] The XYZ drive mechanism / drive circuit 16 uses a stepping motor as a drive actuator to drive the composite measurement head 12 in the XYZ directions (up, down, left, right, forward, and backward) relative to the eye E under examination. The control lever 111 is an operating lever used to manually drive the composite measurement head 12 in the XYZ directions relative to the eye E under examination during alignment adjustments, etc. The power inlet 113 is for plugging in the power cord. The USB input terminal 114 allows connection to a barcode reader or the like via USB for 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.

[0019] As shown in Figure 3, the combined measurement head 12 is positioned inside the cover member 13 opposite the eye E being examined, and performs measurements of multiple measurement items while observing the anterior segment image via the 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 having an image sensor for the anterior segment image, and performs tonometry and pakometry measurements for both the left and right eyes of the subject P. The R / K measurement head 12b is positioned below the T / P measurement head 12a and is composed of an optical system having an image sensor for the anterior segment image, and performs refraction and keratometry measurements for both the left and right eyes of the subject P. 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.

[0020] The cover member 13 covers the composite measurement head 12. When the subject P side of the device body 10 is considered the front, the T / P measurement window 131 is located on the upper front side, 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 positioned 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 on the subject P side.

[0021] As shown in Figures 1 to 3, the face support section 20 is connected to and fixed to the front (front) of the base section 11 of the main body section 10 of the device, and is responsible for supporting the face of the subject P. The face support section 20 comprises a base section 21, a chin rest section 22, a pair of support columns 23, a forehead rest section 24, a drive mechanism 25, and a chin rest paper fastening pin 28.

[0022] The chin rest 22 is provided so as to be able to move up and down relative to the base 21, which is connected and fixed to the base 11, by a drive mechanism 25 (see Figure 4). A pair of support columns 23 are provided protruding from both the left and right sides of the base 21, and the upper ends of this pair of support columns 23 are connected in the X-axis direction to form the forehead rest 24. Height marks 27 for the eye being examined E are set on the sides of the support columns 23.

[0023] For example, as shown in Figure 3, the subject P faces the ophthalmic device 1 while seated on the seat surface 51 of a lifting chair 50 placed in front of the ophthalmic device 1, with their chin resting on the chin rest 22 and their forehead resting against the forehead rest 24, while undergoing eye characteristic measurements. At this time, whether or not the subject P's chin is resting is detected by a detection sensor 26 (see Figure 4), which will be described later.

[0024] As shown in Figure 3, the optical table 30 comprises a tabletop 31, a lifting mechanism 32, a table control unit 33, a power button 34, a lifting lever 35, and a caster base 36.

[0025] 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 includes 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 a caster 36a with a locking mechanism.

[0026] As shown in Figures 1 to 3, the monitor unit 40 is mounted on the top of the back side of the cover member 13 and has a touch panel display screen 41. The monitor unit 40 comprises the display screen 41, a monitor cover member 42, and a monitor support part 43.

[0027] The display screen 41 is a color liquid crystal display that shows 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 has a control circuit unit such as the main control unit 17 built into it. The monitor support member 43 is a member that mounts and supports the monitor unit 40 so that it can rotate around the horizontal axis (X axis or Z axis) and around the vertical axis (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 according to the examiner's position, posture, eye level, etc.

[0028] Next, with reference to Figure 4, the configuration of the control system in the ophthalmic device 1 according to Example 1 will be described.

[0029] As shown in Figure 4, the control system of the ophthalmic device 1 includes a control system for the main body 10, a control system for the face support unit 20, and a control system for the optical table 30.

[0030] The control system of the main unit 10 of the device comprises a main control unit 17 (control unit), internal memory 17a, storage unit 18, measurement optical system 15, XYZ drive mechanism / drive circuit 16, monitor unit 40, storage unit 18, operation unit 19, and wide-angle camera 14.

[0031] 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 lifting lever 35, a power button 34, and a lifting mechanism 32.

[0032] The main control unit 17 loads programs stored in the memory unit 18 or internal memory 17a onto, for example, RAM, and comprehensively controls each part of the ophthalmic device 1, including display control and operation control, in response to operation input signals from the operation unit 19 as appropriate. 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, etc. 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 main body unit 10. The configuration allows for information exchange, such as data output from the main control unit 17 to store data in the database of the external device 60, and retrieval of stored data from the database of the external device 60 in response to requests from the main control unit 17.

[0033] The monitor unit 40 accepts touch operations such as tapping and long-pressing on the display screen 41 as part of the operation of the operation unit 19, and sends an operation input signal 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 supported by the face support unit 20, from a single location onto the image sensor.

[0034] Next, referring to Figure 5, the basic display modes shown on the display screen 41 of the monitor unit 40 from the preparation stage before measurement to the end of measurement will be explained.

[0035] As shown in Figure 5, the touch panel display screen 41 of the monitor unit 40 is configured with an anterior segment image display area 411 for displaying the anterior segment image Gf, an operation button display area 412 for displaying operation buttons, and a measurement status display unit 413 for displaying measurement items.

[0036] The anterior segment image display area 411 is defined as a rectangular area obtained by reducing the total area of ​​the display screen 41 in the vertical and horizontal directions. The anterior segment image display area 411 displays an anterior segment image Gf with 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 as alignment marks at the center of the anterior segment image display area 411.

[0037] In addition to the anterior segment image Gf, the anterior segment image display area 411 also displays the measurement results and number of measurements for each measurement item for both the left and right eyes. For example, in the case of measurement using R / K measurement mode, the two measurement items, REF measurement result, REF measurement number, keratometry measurement result, and keratometry measurement number, are displayed for both the left and right eyes. Furthermore, the corneal vertex distance VD is also displayed in the anterior segment image display area 411.

[0038] The operation button display area 412 is defined as a band-shaped region formed by the top edge and the left and right edges of the four outer edges of the display screen 41, excluding the anterior segment image display area 411 from the total area of ​​the display screen 41.

[0039] 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.

[0040] Mode button 1B is located in the center of the top edge of the operation button display area 412, and when tapped, it displays the first measurement mode selection screen 71, which will be described later. The RK mode display / setting button 2B and TP mode display / setting button 3B are located to the left and right of mode button 1B. The RK mode display / setting button 2B switches to R / K measurement mode when touched, along with the display of R / K measurement mode. The TP mode display / setting button 3B switches to T / P measurement mode when touched, along with the display of T / P measurement mode. Mode button 1B, RK mode display / setting button 2B, and TP mode display / setting button 3B constitute a triple mode button.

[0041] 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.

[0042] On the left side of the operation button display area 412, from top to bottom, are the R button 6B, the all measurement clear button 7B, the all data display button 8B, the exit button 9B, the air check button 10B, the alignment stop button 11B, the jaw rest up / down movement button 12B, and the print button 13B.

[0043] The R button 6B, when tapped, selects the right eye. The Clear All Measurements button 7B, when tapped, clears all measurement data. The Display All Data button 8B, when tapped, displays all measurement data. The Exit button 9B, when tapped, moves the chin rest 22 and the composite measuring head 12 to the exit position. The Air Check button 10B, when tapped, performs an air check. The Alignment Stop button 11B is displayed during measurement, and when tapped, stops alignment or measurement. The Chin Rest Up / Down Movement button 12B, when tapped, moves the chin rest 22 up and down. The Print button 13B, when tapped, prints out the measurement results.

[0044] On the right side of the operation button display area 412, from top to bottom, are 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.

[0045] The L button 14B selects the left eye when tapped. The setup button 15B opens the setup screen when tapped. The cataract button 16B is used when measurement cannot be performed correctly due to cataracts, eyelids, eyelashes, blinking, etc. The corneal diameter button 17B switches to corneal diameter measurement mode when tapped. The FOG button 18B switches between performing FOG mode only on the first measurement or every time during continuous measurement when tapped. The fixation target button 19B changes the brightness of the fixation target when tapped. The start button 20B starts the measurement when tapped. The measurement head advance / retract button 21B moves the composite measurement head 12 closer to / backward from the eye E being examined when tapped. The auto / manual button 22B switches between auto mode and manual mode for ophthalmic measurement.

[0046] The measurement status display unit 413 is located at the bottom edge of the operation button display area 412 and displays the measurement status as icons. The icon display consists of eight types of measurement icons arranged from left to right. The eight types of measurement icons are: right eye keratometry icon Ia, right eye refraction measurement icon Ib, left eye keratometry icon Ic, left eye refraction measurement icon Id, left eye parathyroidism icon Ie, left eye tonomonometry icon If, right eye parathyroidism icon Ig, and right eye tonomonometry icon Ih. The arrangement of these eight types of measurement icons corresponds to the standard measurement order for each measurement item when continuous measurement is performed for all measurement items. Note that the measurement status display is not limited to an icon display using display items as icons; it may also be an English letter display, a simplified English letter display, etc.

[0047] When the measurement mode and measurement items to be performed on the eye E under examination are set, the main control unit 17 makes the set measurement mode and measurement items visible on the measurement status display unit 413. For example, when all measurement modes and measurement items are set, all icons on the measurement status display unit 413 are lit up. When some of the measurement modes and measurement items are set, some of the set icons are lit up. Furthermore, during measurement with multiple measurement items set, the overall display brightness may be changed, the underline may be made brighter, or parentheses or marks may be added to the icons so that the measurement items being measured can be distinguished from the measurement items that are not being measured.

[0048] Next, referring to Figures 6 to 8, the touch operation for setting the measurement mode, measurement items, and measurement eye in the ophthalmic device 1 according to Example 1 will be explained.

[0049] After turning the power switch 112 ON, tap the mode button 1B located at the center of the top edge of the operation button display area 412, as shown in Figure 6. When this tap is performed, the first measurement mode selection screen 71 (Figure 7), which displays the measurement mode and measurement items together, is superimposed on the anterior segment image display area 411 of the display screen 41.

[0050] As shown in Figure 7, the first measurement mode selection screen 71 has the following individual right eye selection buttons: right eye REF measurement button 81RB, right eye keratometry measurement button 82RB, right eye TONOS measurement button 83RB, and right eye PAKY measurement button 84RB. The following individual left eye selection buttons have: left eye REF measurement button 81LB, left eye keratometry measurement button 82LB, left eye TONOS measurement button 83LB, and left eye PAKY measurement button 84LB. The following left and right eye area setting buttons have: right eye setting button 85RB and left eye setting button 85LB. The following measurement mode area setting buttons have: all measurement mode setting button 86AB, R / K measurement mode setting button 86KB, and T / P measurement mode setting button 86PB. Other buttons include: set button 87B, clear button 88B, and screen close button 89B.

[0051] To select all measurement items by touch operation on the first measurement mode selection screen 71, press the all measurement mode setting button 86AB. As shown in Figure 8A, this touch operation illuminates all measurement buttons and setting buttons, including the all measurement mode setting button 86AB, and selects all measurement items.

[0052] To select the right eye measurement items by touch operation on the first measurement mode selection screen 71, press the right eye setting button 85RB. This touch operation illuminates the measurement items for the right eye measurement mode, including the right eye setting button 85RB, as shown in Figure 8B, and the right eye measurement item area is selected. Similarly, to select the left eye measurement items by touch operation on the first measurement mode selection screen 71, press the left eye setting button 85LB to select the left eye measurement item area.

[0053] To select the R / K measurement mode for the left and right eyes by touch operation on the first measurement mode selection screen 71, press the R / K measurement mode setting button 86KB. This touch operation will illuminate the measurement items for the left and right eye R / K measurement modes, including the R / K measurement mode setting button 86KB, as shown in Figure 8C, and the R / K measurement mode area will be selected. Similarly, to select the T / P measurement mode for the left and right eyes by touch operation on the first measurement mode selection screen 71, press the T / P measurement mode setting button 86PB to select the T / P measurement mode area.

[0054] When selecting the R / K measurement mode for the right eye by touch operation on 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 you press the left eye setting button 85LB, the measurement items for the left eye are removed by blackout, and as shown in Figure 8D, the R / K measurement mode area for the right eye is selected by the illuminated circular frame of the remaining measurement items. When selecting the R / K measurement mode for the left eye by touch operation on the first measurement mode selection screen 71, press the right eye setting button 85RB. The area can also be set by the same touch operation when selecting the T / P measurement mode for one of the left or right eyes.

[0055] To confirm the settings for individual measurement items and area measurements using the tap operations described above, press the set button 87B to confirm the settings. To cancel or change the settings, press the clear button 88B to clear the current settings. Furthermore, to finish setting individual measurement items and area measurements, press the screen close button 89B to close the first measurement mode selection screen 71.

[0056] As described above, in the ophthalmic device 1 according to Example 1, the measurement mode, measurement items, and measurement eye can be freely set by touching the first measurement mode selection screen 71, which is displayed by tapping the mode button 1B.

[0057] Next, referring to Figures 9 and 10, the measurement mode, measurement items, and setting operation of the measurement eye in the ophthalmic device 1 according to Example 1, through linkage with the database, will be explained.

[0058] The main control unit 17 of the ophthalmic device 1 according to Example 1 is capable of linking with the database of an external device 60. Therefore, when the measurement mode, measurement items, and measurement eye are set for a specific subject P's eye E, and the ophthalmic measurement is performed according to the settings and completed, the setting history for the measurement mode, measurement items, and measurement eye linked to the specific subject P is stored. At this time, the data is stored in the database of the linked external device 60 as a data list 100 (Figure 9) including the specific subject P so that it can be retrieved.

[0059] Therefore, when a specific subject P undergoes ophthalmic measurements during a follow-up visit, the database of the external device 60 is called, as shown in Figure 9, and a data list 100 is displayed on the screen of the external device 60. Then, the specific subject P for the follow-up visit is selected from the displayed data list 100. By reading the information about subject P that has already been saved through the subject P selection operation, the subject P's ID, measurement mode, measurement items, and measurement eye are set all at once.

[0060] In other words, if subject P undergoes ophthalmic measurements during a follow-up visit and there are no changes to the measurement mode, measurement items, or the eye being measured, it is not necessary to set the measurement mode, measurement items, or the eye being measured on the first measurement mode selection screen 71, which is displayed by tapping the mode button 1B. For example, in the case of subject P who is on a follow-up visit and only requires measurement of the right eye, simply selecting subject P from the data list 100 will display the first measurement mode selection screen 71 with the measurement mode, measurement items, and the eye being measured already set. That is, on the first measurement mode selection screen 71, as shown in Figure 10, the right eye measurement item area will be displayed as selected, similar to when the right eye setting button 85RB is touched.

[0061] Here, we have described an example of calling a database from an external device 60. However, it is also perfectly acceptable to use an example where a database stored in the storage unit 18 of the main unit 10 is called to select a specific subject P. In this case, when the ophthalmic measurement is completed, the setting history of the measurement mode, measurement items, and measured eye is stored in the database of the storage unit 18 of the main unit 10 as a data list linked to the specific subject P.

[0062] As described above, the ophthalmic device 1 according to Example 1 provides the following effects.

[0063] (1) The ophthalmic device 1 comprises a composite measurement head 12 (measurement head), an XYZ drive mechanism / drive circuit 16 (drive mechanism), a monitor unit 40, and a main control unit 17 (control unit). The composite measurement head 12 is positioned opposite the eye E under examination and measures multiple measurement items while observing the anterior segment image Gf via the optical system. The XYZ drive mechanism / drive circuit 16 drives the composite measurement head 12 up, down, left, right, forward, and backward relative to the eye E under examination. The monitor unit 40 has a touch panel type display screen 41 which is set up with an anterior segment image display area 411 that displays the anterior segment image Gf and an operation button display area 412 that displays operation buttons. The main control unit 17 controls each part 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 which displays the measurement mode and measurement items together in the anterior segment image display area 411. By touching the displayed items on the first measurement mode selection screen 71, the measurement mode and measurement items to be performed on the eye E under examination are set.

[0064] Specifically, before or during measurement, tapping the mode button 1B displays the first measurement mode selection screen 71, and by touching the displayed items on the first measurement mode selection screen 71, the measurement mode and measurement items to be performed on the eye E under examination are set. Therefore, the measurement mode and measurement items can be easily set before or during measurement.

[0065] (2) The monitor unit 40 has a measurement status display unit 413 that displays the measurement status on the display screen 41. When the main control unit 17 sets the measurement mode and measurement items to be performed on the eye to be examined E, it displays the set measurement mode and measurement items on the measurement status display unit 413.

[0066] In other words, once the measurement mode and measurement items to be performed on the eye E under examination 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.

[0067] (3) The main control unit 17 displays a right eye setting button 85RB for setting the right eye of the eye to be examined E, and a left eye setting button 85LB for setting the left eye of the eye to be examined E, on the first measurement mode selection screen 71.

[0068] In other words, the first measurement mode selection screen 71 displays the measurement mode and measurement items together with the right eye setting button 85RB and the left eye setting button 85LB. Therefore, the first measurement mode selection screen 71 allows the user to set the measurement mode, measurement items, and the eye being measured simultaneously.

[0069] (4) The main control unit 17 displays individual setting buttons (each measurement button 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 using multiple measurement items.

[0070] In other words, in addition to being able to set measurement items individually, it is also possible to set a measurement item area consisting of multiple measurement items by touching a button. Furthermore, it is also possible to delete some measurement item areas from a measurement item area consisting of a combination of multiple measurement items by touching a button. As a result, the setting of measurement modes and measurement items by touching the first measurement mode selection screen 71 can be done arbitrarily and freely while reducing the number of touch operations.

[0071] (5) When the main control unit 17 has finished the ophthalmic measurement by setting the measurement mode and measurement items to be performed on the eye E to be examined, it stores the setting history of the measurement mode, measurement items and the eye to be examined in the data list 100 of the subject P in the linked database.

[0072] In other words, once the ophthalmic measurements for subject P are completed, the settings history for the measurement mode, measurement items, and measurement eye is stored in the data list for subject P in the linked database. Therefore, when subject P returns for a follow-up visit, the settings for the measurement mode, measurement items, and measurement eye can be changed by referring to the stored settings history. In addition, the stored settings history can be used to perform a batch setting of the measurement mode, measurement items, and measurement eye at the time of the follow-up visit, based on subject P's selection.

[0073] (6) When the subject P is on a follow-up visit, the main control unit 17 displays the data list 100 in the linked database and sets the measurement mode, measurement items, and measurement eye by selecting the follow-up subject P from the data list 100.

[0074] In other words, during follow-up visits, the stored setting history is utilized, and the measurement mode, measurement items, and measurement eye are set simply by selecting the subject P. Therefore, when subject P is on a follow-up visit, the measurement mode, measurement items, and measurement eye can be set quickly and easily. [Examples]

[0075] Example 2 is an example in which the display mode shown on the display screen 41 of the monitor unit 40 from the preparation stage before measurement to the end of measurement, and the display mode of the measurement mode selection screen are different from those of Example 1.

[0076] First, referring to Figure 11, the basic display modes shown on the display screen 41 of the monitor unit 40 from the preparation stage before measurement to the end of measurement will be explained.

[0077] As shown in Figure 11, the touch panel display screen 41 of the monitor unit 40 is configured with an anterior segment image display area 411 for displaying the anterior segment image Gf, an operation button display area 412 for displaying operation buttons, and a measurement status display unit 413 for displaying measurement items.

[0078] The anterior segment image display area 411 is a rectangular area with a reduced area in the vertical and horizontal directions from the total area of ​​the display screen 41, similar to Example 1. The anterior segment image display area 411 displays an anterior segment image Gf having a corneal bright spot image P1, similar to Example 1, and also displays a target area mark 40e and a minimum pupil diameter determination mark 40f at the center of the anterior segment image display area 411. In addition to the anterior segment image Gf, the anterior segment image display area 411 also displays the measurement results and the number of measurements for each of the left and right eyes, similar to Example 1.

[0079] The operation button display area 412 is defined as a band-shaped region formed by the top, bottom, right, and upper left sides of the four outer edges of the display screen 41, excluding the anterior segment image display area 411 from the total area of ​​the display screen 41.

[0080] 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 Embodiment 1.

[0081] At the top left of the operation button display area 412, the following buttons are arranged from top to bottom: the R button 6B, the jaw rest up / down movement button 12B, and the exit button 9B.

[0082] On the right side of the operation button display area 412, from top to bottom, are the L button 14B, the measuring head forward / reverse button 21B, the start button 20B, and the auto / manual button 22B.

[0083] At the bottom edge of the operation button display area 412, from left to right, are the cataract button 16B, the fixation target button 19B, the FOG button 18B, the all data display button 8B, the print button 13B, the corneal diameter button 17B, and the all measurement clear button 7B.

[0084] The measurement status display unit 413 is located at the lower left edge of the operation button display area 412 and displays the measurement status in simplified English characters. The simplified English character display unit includes a measurement mode display unit MA, a first measurement item display unit IA, and a second measurement item display unit IB. The measurement mode display unit MA displays "R / K" to indicate R / K measurement mode, or "T / P" to indicate T / P measurement mode. The first measurement item display unit IA displays "KRT" to indicate keratinometer measurement, or "TONO" to indicate tonometer measurement. The second measurement item display unit IB displays "REF" to indicate ref measurement, or "PACHY" to indicate pachylazole measurement.

[0085] Next, referring to Figures 12 to 14, the touch operation for setting the measurement mode, measurement items, and measurement eye in the ophthalmic device 1 according to Example 2 will be explained.

[0086] After turning the power switch 112 ON, tap the mode button 1B, which is located in the center of the top edge of the operation button display area 412. When this tap is performed, as shown in Figure 12, the second measurement mode selection screen 72, which displays the measurement mode and measurement items together, is superimposed on the anterior segment image display area 411 of the display screen 41.

[0087] As shown in Figure 13, the second measurement mode selection screen 72 has individual selection buttons: a REF measurement button 91B and a keratin measurement button 92B in R / K measurement mode, and a TONOS measurement button 93B and a PAKI measurement button 94B in T / P measurement mode. Other buttons include an OK button 95B and a Cancel button 96B.

[0088] In Example 1, the first measurement mode selection screen 71 was shown, which integrated the settings for the measurement mode, measurement items, and measurement eye. However, in Example 2, the settings for the measurement mode and measurement items are separated from the settings for the measurement eye. The reasons for this are, firstly, that by setting the measurement mode and measurement items for one eye at a time while observing the subject P, the examiner can concentrate on the subject P while performing the measurement. Secondly, in facilities where the measurement items do not differ significantly between the two eyes, being able to set only the measurement mode and measurement items does not interfere with normal medical practice.

[0089] The settings for the measurement mode and measurement items are shared among the following buttons: REF measurement button 91B, keratin measurement button 92B, tonometer measurement button 93B, PAKY measurement button 94B, RK mode display / setting button 2B, and TP mode display / setting button 3B.

[0090] The setting of the measurement eye 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 key icons, as shown in Figure 14A. On the other hand, when setting only one eye, for example, the left eye, the key icon processing is performed to display the IK key icon partially overlapping the R button 6B, as shown in Figure 14B, and the L button 14B is displayed without a key icon.

[0091] Next, referring to Figures 15A to 15D, we will explain the operation of the measurement status display when setting operation cases #1 to #4 are selected on the second measurement mode selection screen 72.

[0092] In the second measurement mode selection screen 72, setting operation case #1 is defined as when the R / K measurement mode is set by touch operation using the refraction measurement button 91B and the keratometry measurement button 92B. In setting operation case #1, as shown in Figure 15A, the "RK" on the RK mode display / setting button 2B lights up, and "R / K" lights up on the measurement mode display MA of the measurement status display unit 413. This display on the display screen 41 makes it visually clear that the R / K measurement mode (refraction measurement, keratometry measurement) is set.

[0093] In the second measurement mode selection screen 72, setting operation case #2 is defined as when only the R / K measurement mode REF measurement button 91B is set by touch operation. In setting operation case #2, as shown in Figure 15B, the "RK" on the RK mode display / setting button 2B lights up, and "REF" lights up on the second measurement item display IB of the measurement status display unit 413. This display on the display screen 41 makes it visually clear that the R / K measurement mode REF measurement is set.

[0094] To set only the refraction measurement in R / K measurement mode, touch the RK mode display / setting button 2B and the second measurement item display unit IB. It is also possible to perform temporary manual settings without opening the second measurement mode selection screen 72 by touching buttons not present on the second measurement mode selection screen 72.

[0095] In the second measurement mode selection screen 72, setting operation case #3 is defined as the setting made by touching the REF measurement button 91B for R / K measurement mode and the TONO measurement button 93B for T / P measurement mode. In setting operation case #3, as shown in Figure 15C, during measurement in R / K measurement mode, the "RK" on the RK mode display / setting button 2B lights up, and "REF" lights up on the second measurement item display IB of the measurement status display unit 413. When the R / K measurement mode ends and the system transitions to T / P measurement mode, the measurement status display unit 413 switches to the T / P measurement mode display, and "TONO" lights up on the first measurement item display IA. This display on the display screen 41 makes it visually clear that the system is set to transition from REF measurement in R / K measurement mode to TONO measurement in T / P measurement mode.

[0096] In the second measurement mode selection screen 72, setting operation case #4 is defined as when the tono measurement button 93B and the paki measurement button 94B for T / P measurement mode are set by touch operation. In setting operation case #4, as shown in Figure 15D, the "TP" on the TP mode display / setting button 3B lights up, and "T / P" lights up on the measurement mode display MA of the measurement status display unit 413. This display on the display screen 41 makes it visible that the T / P measurement mode (tonno measurement, paki measurement) is set.

[0097] Next, referring to Figures 16A and 16B, we will explain the transition process to an unselected T / P measurement mode by long-press operation.

[0098] In setting operation case #1 (upper left of Figure 16A), the "RK" on the RK mode display / setting button 2B lights up, and "R / K" lights up on the measurement mode display 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.

[0099] Switching the measurement head causes the illuminated button to change from RK mode display / setting button 2B to TP mode display / setting button 3B. Simultaneously, the display on the measurement status display unit 413 also changes from R / K measurement mode to T / P measurement mode, and "T / P" is illuminated on the measurement mode display unit MA (lower right part of Figure 16A).

[0100] Therefore, if you tap the mode button 1B during measurement, the second measurement mode selection screen 72 will be displayed (upper right of Figure 16A). On the second measurement mode selection screen 72, the REF measurement button 91B and keratin measurement button 92B for R / K measurement mode, and the TONOS measurement button 93B and PAKY measurement button 94B for T / P measurement mode will light up.

[0101] In setting operation case #2 (upper left of Figure 16B), the "RK" on the RK mode display / setting button 2B lights up, and the "REF" on the second measurement item display IB of the measurement status display unit 413 lights up (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.

[0102] Switching the measurement head causes the illuminated button to change from RK mode display / setting button 2B to TP mode display / setting button 3B. Simultaneously, the display on the measurement status display unit 413 also changes from R / K measurement mode to T / P measurement mode, and "T / P" is illuminated on the measurement mode display unit MA (lower right part of Figure 16B).

[0103] Therefore, if you tap the mode button 1B during measurement, the second measurement mode selection screen 72 will be displayed (upper right of Figure 16B). On the second measurement mode selection screen 72, only the reflector measurement button 91B for R / K measurement mode and the tono measurement button 93B and pak measurement button 94B for T / P measurement mode will be lit up.

[0104] As explained above, in addition to the effects of (1), (2), (5), and (6) above, the ophthalmic device 1 of Example 2 provides the following effects.

[0105] (7) The combined measuring head 12 includes a T / P measuring head 12a used in T / P measurement mode and an R / K measuring head 12b used in 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 or R / K measurement mode is not set, the main control unit 17 switches the measuring head and transitions to the unset measurement mode when the other measurement mode display / setting button is pressed and held.

[0106] 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 will switch the composite measurement head 12 to the T / P measurement head 12a, transitioning to an unset T / P measurement mode. Therefore, when you want to transition to an unset measurement mode in the middle of a measurement, you can skip the setting operation on the second measurement mode selection screen 72, which is displayed by tapping the mode button 1B, by simply pressing and holding one button. [Examples]

[0107] Example 3 is an example in which, when setting measurement items on the measurement mode selection screen, at least one of the measurement order and the number of measurements can be set.

[0108] Next, referring to Figures 17 to 19, the tapping operation in the ophthalmic device 1 according to Example 3 will be used to explain the setting of the measurement mode, measurement items, measurement eye, measurement order, and number of measurements.

[0109] After turning the power switch 112 ON, tap the mode button 1B located in the center of the top edge of the operation button display area 412. When this tap is performed, as shown in Figure 12, the third measurement mode selection screen 73 is displayed superimposed on the anterior segment image display area 411 of the display screen 41, and displays the measurement mode and measurement items together.

[0110] 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. In addition, there are individual selection buttons for the left and right eyes: a REF measurement button 91B and a keratometry measurement button 92B in R / K measurement mode, and a TONOS measurement button 93B and a PAKY measurement button 94B in T / P measurement mode. Furthermore, there is a number setting button 97B for the right eye and a number setting button 98B for the left eye, each of the four measurement buttons. Other buttons include an OK button 95B and a Cancel button 96B.

[0111] To set the measurement mode, touch the REF measurement button 91B and the keratometry measurement button 92B with either both eyes or one eye to set the R / K measurement mode. Alternatively, touch the TON measurement button 93B and the PAKY measurement button 94B with either both eyes or one eye to set the T / P measurement mode.

[0112] To set the measurement items, touching only the REF measurement button 91B or keratometry measurement button 92B for both eyes or one eye will set the measurement item for only one eye in R / K measurement mode. Alternatively, touching only the TON measurement button 93B or PAKY measurement button 94B for both eyes or one eye will set the measurement item for only one eye in T / P measurement mode.

[0113] To set the measurement eye, tap both the R button 6B and the L button 14B if you want to set both eyes. If you want to set one eye, tap only the button for the eye you want to set from the R button 6B and L button 14B.

[0114] The measurement order is set by tapping the number setting buttons 97B and 98B, as shown in Figure 18, to determine the measurement order (1 to 8), for example, by the number of taps on each of the eight number setting buttons 97B and 98B. In the example shown in Figure 18, 1 is the right keratometer measurement, 2 is the right refractor measurement, 3 is the right pulsate measurement, 4 is the right tonometer measurement, 5 is the left keratometer measurement, 6 is the left refractor measurement, 7 is the left pulsate measurement, and 8 is the left tonometer measurement.

[0115] The number of measurements is set for the number setting buttons 97B and 98B, as shown in Figure 19, by the number of taps on each of the eight number setting buttons 97B and 98B. In the example shown in Figure 19, the right keratometer measurement is set to 3 times, the right refraction measurement to 3 times, the right pulse measurement to 2 times, the right tono measurement to 1 time, the left keratometer measurement to 3 times, the left refraction measurement to 3 times, the left pulse measurement to 2 times, and the left tono measurement to 1 time.

[0116] Here, the measurement order and the number of measurements can be set individually 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 measurement number setting mode screen.

[0117] As explained above, in addition to the effects (1) to (7) above, the ophthalmic device 1 of Example 3 provides the following effects.

[0118] (8) The main control unit 17 makes the third measurement mode selection screen 73, which is displayed when setting the measurement mode and measurement items, a display screen that allows setting the measurement order of the measurement items. Therefore, by operating on the third measurement mode selection screen 73, it is possible to set the measurement order when measuring multiple measurement items in succession.

[0119] (9) The main control unit 17 makes the third measurement mode selection screen 73, which is displayed when setting the measurement mode and measurement items, a display screen that allows setting the number of measurements for each measurement item. Therefore, when measuring multiple measurement items, the number of measurements for each measurement item can be set by operating the third measurement mode selection screen 73.

[0120] The ophthalmic apparatus of the present invention has been described above based on Examples 1 to 3. However, the specific configuration is not limited to these examples. Changes and additions to the design are permitted as long as they do not deviate from the gist of the invention as described in each claim of the patent.

[0121] Examples 1 to 3 show an ophthalmic device 1 equipped with a composite measurement head 12 that uses a T / P measurement head 12a (first measurement head) and an R / K measurement head 12b (second measurement head) as the measurement head. However, the measurement head is not limited to the composite measurement head used in Examples 1 to 3, and any measurement head that has multiple measurement modes and multiple measurement items, and where the measurement mode and measurement items can be changed before or during measurement, is acceptable. In addition to the T / P measurement head and R / K measurement head, various ocular characteristic measurement heads for the eye under examination may also be used, such as a corneal shape measurement head, fundus photography head, axial length measurement head, endothelial cell measurement head, etc.

[0122] In Example 1, an example of a first measurement mode selection screen 71 was shown, in which the measurement mode, measurement items, and measurement eye settings can be freely set arbitrarily by touch operation on buttons. In Example 2, an example of a second measurement mode selection screen 72 was shown, in which the settings for the measurement mode and measurement items are separated from the settings for the measurement eye. In Example 3, an example of a third measurement mode selection screen 73 was shown, in 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 form are also acceptable. For example, as shown in Figure 20, a fourth measurement mode selection screen 74 is also acceptable, in which the measurement mode, measurement items, and measurement eye can be selected one by one. Note that the reference numerals in Figure 20 are the same as those used in the first measurement mode selection screen 71.

[0123] Examples 1-3 show that the measurement mode selection screen is displayed by tapping the mode button, and the measurement mode and measurement items to be performed on the eye under examination are set by touch operation on the displayed items on the measurement mode selection screen. Then, once the measurement mode and measurement items are set, the set measurement mode and measurement items are displayed on the measurement status display unit. However, regarding the display on the measurement mode selection screen or the display on the measurement status display unit, a memory call function may be added to Examples 1-3 so that the display switches to the set display via an automatic call depending on the day of the week and time of day, or switches to the set display simply by making a call operation. Here, "memory call function" refers to a function that, when the measurement mode and measurement items to be performed according to a predetermined prescription are set and stored via memory operation, will automatically call or allow the display based on the stored measurement mode and measurement items to be obtained by making a call operation the next time. For example, in the case of prescriptions by a glaucoma specialist, eyeglass prescriptions, contact lens prescriptions, etc., where the day of the week and time of day for measurement are determined, the day of the week and time of day are stored along with the settings, and an automatic call is used to automatically recall the settings when the stored day of the week and time of day arrives. Furthermore, for example, in the case of a standard basic eyeglass prescription where the day of the week or time of measurement is not specifically designated, a call operation is used to recall the stored settings with the press of a button. This memory call function eliminates the need to go to the setup screen and select measurement items one by one from the initial settings each time a measurement is started, thus reducing the operational burden on the examiner.

[0124] Examples 1 to 3 show an ophthalmic device 1 in which the display screen 41 of a monitor unit 40 attached to the main unit 10 of the device serves as the operation unit 19, and measurements are taken while the subject P and the examiner are facing each other at close range. However, the operation unit could also be, for example, a detachable monitor unit, which the examiner could take out and remotely operate from another room. Alternatively, an external device such as a personal computer, tablet, smartphone, or other information terminal or dedicated terminal with a touch panel display screen could be used as the monitor unit, separate from the monitor unit attached to the main unit of the device, and connected to the main unit of the device via wireless communication. In this case, if the external device serving as the monitor unit is installed in a desired location away from the ophthalmic device, ophthalmic measurements can be performed remotely while visually observing the subject's condition from the location where the external device is installed.
