[0002] BACKGROUND ART Conventionally, there is known an ophthalmic device control method for wirelessly controlling both an electric refractor and an optotype presenting device by using a tablet computer (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6206430 Summary of the Invention [Problem to be solved by the invention]

[0004] There is a strong need for an ophthalmic device that allows examinations to be performed using a tablet, in order to comply with social distancing and other requirements. However, in a proximity examination mode in which an examiner sitting near the examinee performs input operations on the ophthalmic device, an input operation device that combines a monitor screen with an operation controller having a manually operated jog dial or the like is used. For this reason, in a remote examination mode, it is difficult to achieve the operational feel of an examiner who is accustomed to manually operating a jog dial or the like using only a tablet. Furthermore, when using a tablet, it is difficult to input quantitative information, and blind operation is not possible. Therefore, when performing a remote examination using only a tablet, even if social distancing can be complied with, there is a problem in that the examiner's input operation burden increases.

[0005] The present disclosure has been made with a focus on the above-mentioned problems, and aims to provide an ophthalmic device that reduces the input operation burden on an examiner when performing a remote examination by remote operation from an examiner who is located at a distance from the subject. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the ophthalmic device disclosed herein comprises a measurement head that performs measurements of examination items on the subject's eye, a control unit that controls the measurement head based on input information, and a remote operating device that transmits the input information to the control unit via wireless communication. The remote operation device uses a touch operation terminal having a touch panel display screen and a manual operation unit that cooperates with the touch operation terminal. The manual operation unit has a quantitative content operation means that enables the examiner to input quantitative content by moving his / her hand in a predetermined direction. [Effects of the Invention]

[0007] The present disclosure employs the above-described means for solving the problem, thereby reducing the input operation burden on the examiner when a remote examination is performed by remote operation from an examiner who is distant from the subject. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Below, as forms for implementing the ophthalmic device according to the present disclosure, an example of using a subjective ophthalmic device as an ophthalmic examination system (Example 1), an example of using a subjective / objective ophthalmic device as an ophthalmic examination system (Example 2), and an example of using an objective ophthalmic device as an ophthalmic examination system (Example 3) will be described with reference to the drawings. [Example]

[0010] The ophthalmic apparatus 10 according to the first embodiment is an example of a subjective ophthalmic apparatus that performs a subjective ophthalmic examination of the subject's eye E. In the following, the left-right direction as viewed from the subject S is indicated by arrow X, the up-down direction (vertical direction) is indicated by arrow Y, and the direction perpendicular to the left-right and up-down directions (depth direction) is indicated as the front-rear direction by arrow Z. Note that an ophthalmic examination in which measurements are carried out while listening to responses from the subject S is referred to as a "subjective ophthalmic examination," and an ophthalmic examination in which measurements are automatically performed by a machine is referred to as an "objective ophthalmic examination."

[0011] The ophthalmic device 10 constitutes a subjective ophthalmic device and is used to measure the refractive power of the subject's eye E and to test binocular visual function. The ophthalmic device 10 of Example 1 is a binocular open-type device that can test and correct the visual function of the subject's eye E while the subject S has both eyes open, and can also cover one eye and test each eye at a time. Furthermore, the convergence and divergence forces of the subject S are measured, and the results are used as reference values ​​when correcting the subject's heterophoria.

[0012] 1, the ophthalmologic apparatus 10 includes a refractor head 11 (measurement head), an optotype display device 12, an optometry table 14, a power supply unit 19 (controller), and a remote operation device 50. The optometry table 14 has a first table portion 15 that supports the refractor head 11 and on which the arm of the subject S is placed, and a second table portion 16 on which the optotype display device 12 is placed.

[0013] The first table section 15 can be moved up and down by a first lifting mechanism 17 and can be stopped at any position in the vertical direction. The second table section 16 can be moved up and down relative to the first table section 15 by a second lifting mechanism 18, as shown in Figures 2 and 3, and can be moved between a position where the optotype display device 12 faces the subject's eye E (see Figure 2) and a position where it is out of the field of view (direction of line of sight) of the subject's eye E (see Figure 3).

[0014] As shown in FIG. 1, the refractor head 11 has a pair of optometry units 21 and a support mechanism 22. The pair of optometry units 21 are attached to the first table portion 15 of the optometry table 14 by the support mechanism 22. The support mechanism 22 has a support post 22a, a support arm 22b, and a support member 22c. The support post 22a extends vertically from above the first table portion 15 and is extendable and retractable in the vertical direction and rotatable in the circumferential direction, as indicated by the arrows. The support arm 22b extends horizontally (diagonally upward) from the support post 22a. A support member 22c is provided at the tip of the support arm 22b, and the refractor head 11 is suspended from the support member 22c. The support mechanism 22 can rotate the support pillar 22a in a circumferential direction to position the refractor head 11 between the test eye E and the target display device 12 (see Figure 2), and can also retract the refractor head 11 from there (see Figure 1).

[0015] The optometry units 21 are provided with a forehead rest against which the forehead of the subject S rests, and are provided in pairs on the left and right to correspond to the left and right eyes E of the subject S positioned there, and each constitutes an optometry optical system for the left eye and an optometry optical system for the right eye. Hereinafter, when referring to each unit individually, the optometry unit for the left eye will be referred to as the optometry unit 21L and the optometry unit for the right eye will be referred to as the optometry unit 21R. Each optometry unit 21 is attached to the support member 22c of the support mechanism 22 by a known slide mechanism so as to be slidable in the left-right direction (X direction), allowing them to be moved closer to each other and for communication to be established.

[0016] Each of the optometry units 21 is provided with an optometry window 23L, 23R. Each of the optometry windows 23L, 23R forms an optical path from the subject's eye E side of the corresponding optometry unit 21 to the optotype display device 12 side, and allows for the selective placement of optical elements (not shown) used for optometry. The optical elements are an assembly of various lenses, polarizing elements, etc. used to correct the visual function of the subject's eye E, and include, for example, polarizing filters, spherical lenses, cylindrical lenses, and prisms.

[0017] The refractor head 11 is provided with a near point rod 27 extending vertically on the optotype display device 12 side of each of the optometry units 21. A near point rod 27 has an optotype display unit 28 for near vision optometry hanging from its tip. The near point rod 27 is foldable, and when in use, the optotype display unit 28 is positioned at the near vision optometry distance (e.g., 300 to 400 mm) (see Figure 3), and when not in use, the near point rod 27 and optotype display unit 28 are stored vertically (see Figures 1 and 2). The optotype display unit 28 displays an optotype for near vision optometry. The refractor head 11 is also provided with a subject microphone 31 for acquiring voice and an internal speaker 32 for outputting voice.

[0018] As shown in Fig. 1, the optotype display device 12 is placed on the second table 16 and is arranged in front of the subject's eye E across the refractor head 11 on the first table 15. The optotype display device 12 has a rectangular parallelepiped housing 41, which houses an optotype presenting optical system and an optotype control unit (not shown). The housing 41 has a partially open upper front surface (toward the subject's eye E) and a window 41a through which the subject S can view the optotype. In addition, a subject imaging unit 47 for imaging the subject S is provided below the window 41a.

[0019] The power supply unit 19 is a unit that incorporates a personal computer that has the function of comprehensively controlling the operations of each part of the ophthalmologic apparatus 10. The refractor head 11 and the optotype display device 12 are connected to the power supply unit 19 via a LAN cable. When an input operation device (e.g., a wired controller) not shown in the figure is used in the proximity test mode, the input operation device is connected to the power supply unit 19 via a LAN cable.

[0020] An example of the operation when performing distance and near vision optometry in subjective optometry using the ophthalmic apparatus 10 shown in FIG. 1 will be described with reference to FIGS. 2 and 3. FIG.

[0021] First, a distance eye examination is performed using the optotype display device 12. At this time, in the ophthalmic apparatus 10, as shown in FIG. 2, the support 22a is rotated as appropriate to position the refractor head 11 in front of the window 41a of the optotype display device 12. The subject S, standing or seated on a chair, faces the optotype display device 12 (window 41a) on the second table unit 16 with the refractor head 11 on the first table unit 15 between them, places their forehead on the forehead rest, and rests their elbows and arms on the first table unit 15, assuming the eye examination posture. Then, the ophthalmic apparatus 10 moves the first table unit 15 and the second table unit 16 up and down as appropriate depending on the condition of the subject S, such as their posture (standing or sitting), height, sitting height, and height of the subject's eye E from the floor, i.e., to match the height of the subject's eye E in a natural posture. As a result, the vertical height of the refractor head 11 and the target display device 12 of the ophthalmologic apparatus 10 is adjusted, and the height of the eye examination unit 21 is finely adjusted by extending and contracting the support 22a to fit the eye E to be examined.

[0022] Thereafter, the ophthalmic apparatus 10 displays an optotype for distance vision examination suited to the purpose on the optotype display device 12, and presents the optotype image at the distance vision examination distance using the optotype presenting optical system 42. The ophthalmic apparatus 10 performs distance vision examination of the subject's eye E by having the subject S gaze at the optotype image through the examination windows 23L, 23R of the left and right examination units 21L, 21R. Then, the ophthalmic apparatus 10 changes the power of the refractive lenses and the power of the prisms in the examination windows 23L, 23R of the refractor head 11 according to how the optotype image appears in this distance vision state, thereby correcting refractive errors, heterophoria, and the like in the distance vision state.

[0023] Next, the ophthalmic apparatus 10 performs near vision eye examination using the optotype display device 12. At this time, as shown in Fig. 3, the ophthalmic apparatus 10 lowers the second table portion 16 and places the optotype display portion 28 hanging from the tilted near point rod 27 in the space above it.

[0024] Thereafter, the ophthalmic apparatus 10 performs a near vision optometry examination of the subject's eye E by having the subject S gaze at the near vision optometry target on the optotype display unit 28 through the optometry windows 23L and 23R of the left and right optometry units 21L and 21R according to the purpose. The ophthalmic apparatus 10 then changes the power of the refractive lenses and the power of the prisms arranged in the optometry windows 23L and 23R in the refractor head 11 according to how the optotype appears in the near vision state, thereby correcting refractive errors, heterophoria, and the like in the near vision state. In this way, the ophthalmic apparatus 10 can examine changes in the accommodation power of the subject's eye E due to aging, etc.

[0025] Next, the detailed configuration of the remote control device 50 will be described with reference to FIG.

[0026] The remote operating device 50 is a device that transmits input information to the power supply unit 19 via wireless communication, and is used in a remote examination mode in which an examiner located at a distance of at least the social distance from the subject S operates the ophthalmic device 10.

[0027] The remote operation device 50 uses a tablet terminal 51 (touch operation terminal) having a touch panel display screen 51a and a manual operation unit 52 that cooperates with the tablet terminal 51. The remote operation device 50 can be used by placing it on a table or by holding it in one's hand. When the remote operation device 50 is used by placing it on a table, for example, as shown in FIG. 6, a tiltable tilt connection mechanism 53 is provided on the manual operation unit 52, and the tablet terminal 51 is inserted into a tablet terminal storage section 53a of the tilt connection mechanism 53 to connect it. In this case, the screen tilt angle of the tablet terminal 51 can be adjusted to an appropriate angle within a predetermined tilt angle range relative to the manual operation unit 52.

[0028] The tablet terminal 51 is network-connected to the power supply unit 19 via cable-free wireless LAN communication. In the remote inspection mode, the touch panel display screen 51a displays a plurality of pieces of input operation selection information that are selected mainly by touch operation, as shown in FIG.

[0029] The manual operation unit 52 is detachably provided on the lower peripheral end surface of the tablet terminal 51 and can be in an attached state or a detached proximity state. Here, the attached state includes both a state in which it is attached to the tablet terminal 51 by plugging it in and a state in which it is connected to the tablet terminal 51 via a cable. The detached proximity state refers to a state in which they are arranged so that they can communicate information with each other via short-range wireless communication. Therefore, the tablet terminal 51 and the manual operation unit 52 of the remote operation device 50 can cooperate not only in the attached state but also in the detached proximity state.

[0030] The manual operation unit 52 includes a unit power supply 52a, a microswitch 52b (attachment state detection means) that detects the attachment state of the tablet terminal 51, and a short-range communicator 52c for the tablet terminal 51. The unit power supply 52a is turned on and off by a power switch 503. The short-range communicator 52c also detects the proximity state by determining the communication status.

[0031] When the microswitch 52b detects that the tablet terminal 51 and the manual operation unit 52 are in an attached state, or when the microswitch 52b detects that the tablet terminal 51 and the manual operation unit 52 are in a detached proximity state, a predetermined reaction action is set.

[0032] The predetermined reaction actions include, for example, disabling tablet operation, prioritizing tablet operation, both tablet operation and manual operation, power mode (power saving mode), active (data exchange), and termination determination.

[0033] The manual operation unit 52 includes a jog dial 500 (quantitative content operation means) that allows the examiner to input quantitative information by moving their hand in a predetermined direction. The jog dial 500 is used when changing the numerical values ​​of the lens refractive power or astigmatism axis, etc. Turning it clockwise changes the value to the negative side, and turning it counterclockwise changes the value to the positive side. Here, the "jog dial" is a rotary selector that operates simply by "turning and pressing" the dial. For example, quantitative information can be input in detail by using a jog operation that changes the amount little by little in steps, with a predetermined change amount defined as a step unit. In other words, while the touch-operated tablet terminal 51 is not good at inputting quantitative information, the jog dial 500 is an operation means that is well suited to inputting quantitative information.

[0034] The jog dial 500 can be used in combination with a touch operation on the display screen 51a of the tablet terminal 51. Screen touch operations that can be combined with the input operation of quantitative content to the jog dial 500 include operation of spherical power / addition power, operation of astigmatism power, operation of astigmatism axis, operation of horizontal / vertical prism, operation of PD, etc. Note that "PD" refers to the interpupillary distance between the centers of the left and right pupils (irises) of the subject's eye E. Furthermore, while a shift switch 515 (described later) is pressed, the change step for each operation becomes a default value.

[0035] The manual operation unit 52 includes a first peripheral switch group 501 arranged at peripheral positions of the jog dial 500 .

[0036] As shown in FIG. 4, the first peripheral switch group 501 has a forward switch 510, a first switch 511, a second switch 512, a plus switch 513, a minus switch 514, and a shift switch 515.

[0037] The forward switch 510 advances the course program by one step, and pressing it while pressing the shift switch 515 moves the course program back by one step. The first switch 511, in monocular mode, sets a green-framed cross cylinder lens on the eye being tested and starts the test. In binocular mode, the test automatically starts in right eye test mode. The second switch 512, in monocular mode, sets a red-framed cross cylinder lens on the eye being tested and starts the test. In binocular mode, the test automatically starts in right eye test mode. The plus switch 513 is green, and the value changes to the plus side each time it is pressed. The minus switch 514 is red, and the value changes to the minus side each time it is pressed. The shift switch 515 is used in combination with the forward switch 510, etc.

[0038] Here, the plus switch 513 and the minus switch 514 can be used in combination with a screen touch operation on the display screen 51a of the tablet terminal 51. Screen touch operations that can be combined with operations on the plus switch 513 and the minus switch 514 include operations during spherical power / addition power operation, astigmatism power operation, astigmatism axis operation, horizontal / vertical prism operation, and PD operation. Note that while the shift switch 515 is pressed, the change step for each operation becomes the default value.

[0039] Here, the peripheral switch group may include, as shown in Figure 5, a first peripheral switch group 501, 501' arranged around the jog dial 500, and a second peripheral switch group 502 arranged at a position farther from the jog dial 500 than the first peripheral switch group 501, 501'.

[0040] As described above, the first peripheral switch group 501 has the forward switch 510, the first switch 511, the second switch 512, the plus switch 513, the minus switch 514, and the shift switch 515.

[0041] The first peripheral switch group 501' has a right eye switch 516, a left eye switch 517, a binocular switch 518, and occlusion switches 519 and 520. The right eye switch 516 specifies the right eye as the eye to be tested. The left eye switch 517 specifies the left eye as the eye to be tested. The binocular switch 518 sets the binocular measurement state. The occlusion switches 519 and 520 set the occlusion for the right or left eye. Pressing them again removes the occlusion. Pressing them while pressing the shift switch 515 allows you to change the type of occlusion.

[0042] The second peripheral switch group 502 includes a movement switch 521 and an acuity switch 522. The movement switch 521 is used to move the selection items of a mask or list, and includes an upward movement switch section 521a, a downward movement switch section 521b, a leftward movement switch section 521c, and a rightward movement switch section 521d. The acuity switch 522 is located in the center of each switch section 521a, 521b, 521c, and 521d, and is used to input a measured acuity value. A jog dial may be located in the center of the second peripheral switch group 502, and the jog dial and the second peripheral switch group 502 may be combined.

[0043] In the manual operation unit 52 of the first embodiment, the following parameter input operations are performed by manually operating the jog dial 500. (P1) The test distance between the subject's eye E and the test target is set. (P2) Set the optotype switching, auxiliary lens switching, mask switching, and data switching. (P3) Set the adjustment amount of the amount of convergence and divergence. (P4) Change the patient explanation display, select menu items, enter numerical values ​​such as the patient number, and set the fixation light intensity, target XY position, spherical refraction value [S], cylindrical refraction value [C], axial angle [A], and prism [P].

[0044] Here, "amount of convergence and divergence" refers to the eye movement that occurs when the subject S moves their gaze to an object at a different distance (depth) from them, with both eyes moving in different directions. When the eyes come together when looking at something close, this is called "convergence," and when the eyes move apart when looking at something far away, this is called "divergence."

[0045] Next, we will explain the parameter input operation in remote examination mode. There is a high demand for ophthalmic devices that allow examinations to be performed using a tablet in response to social distancing, and this has been proposed in the above-mentioned prior art document (Japanese Patent No. 6206430) and other documents.

[0046] However, in the proximity examination mode in which an examiner sitting near the subject performs input operations on the ophthalmic device, a device that combines a monitor screen with an operation controller having a manually operated jog dial, control lever, etc. is generally used as the input operation device.

[0047] For this reason, in remote examination mode, it is difficult for examiners who are accustomed to manually operating jog dials, control levers, etc. to achieve the same operational feel as in close-proximity examination mode using only tablet operation. Furthermore, while tablet operation is convenient for selecting from multiple options, it is difficult to input quantitative information and blind operation is not possible. Therefore, when remote examinations are performed using only tablet operation to comply with social distancing, the examiner's input burden increases.

[0048] In contrast, the remote operation device 50 used in the remote examination mode uses a tablet terminal 51 having a touch panel display screen 51a and a manual operation unit 52 linked to the tablet terminal 51. The manual operation unit 52 employs a configuration having a jog dial 500 as quantitative content operation means that enables the examiner to input quantitative content by moving his / her hand in a predetermined direction.

[0049] Therefore, in the remote examination mode, the advantage of the tablet terminal 51, which is convenient for selecting from multiple options, is utilized, while the jog dial 500 compensates for the difficulty of inputting quantitative content and blind operation, which the tablet terminal 51 is not good at. Also, the operating feel of an examiner who is accustomed to manually operating a jog dial, etc. in the proximity examination mode is realized in the remote examination mode. Therefore, when a remote examination is performed by an examiner who is distant from the subject S and operates remotely, the burden of input operations on the examiner is reduced.

[0050] The ophthalmologic apparatus 10 of the first embodiment has the following advantages.

[0051] (1) The device includes a measurement head (refractor head 11) that measures the test items on the subject's eye E, a control unit (power supply unit 19) that controls the measurement head based on input information, and a remote operation device 50 that transmits the input information to the control unit via wireless communication. The remote operation device 50 uses a touch operation terminal (tablet terminal 51) with a touch panel display screen and a manual operation unit 52 that cooperates with the touch operation terminal. The manual operation unit 52 has a quantitative content operation means (jog dial 500) that allows the examiner to input quantitative content by moving their hand in a predetermined direction. Therefore, when a remote examination is performed by an examiner remotely operating the device from a distance from the subject S, the burden of input operations on the examiner can be reduced.

[0052] (2) The manual operation unit 52 includes a group of peripheral switches (first group of peripheral switches 501, 501', etc.) arranged around the quantitative content operation means (jog dial 500). Therefore, in addition to the combined operation of the quantitative content operation means (jog dial 500) and the touch operation terminal (tablet terminal 51), it is possible to add the combined operation of the quantitative content operation means (jog dial 500) and the group of peripheral switches (first group of peripheral switches 501, 501', etc.). This further reduces the input operation burden on the examiner when performing a remote examination.

[0053] (3) The peripheral switch group includes a first peripheral switch group 501, 501' and a second peripheral switch group 502, which are arranged around the jog dial 500 (quantitative content operation means). Therefore, by setting the first peripheral switch group 501, 501' and the second peripheral switch group 502 to switch groups that allow intuitive and smart operation, it is possible to improve operability when performing remote testing.

[0054] (4) The manual operation unit 52 is provided so as to be able to be attached to the touch operation terminal (tablet terminal 51) or detached and in close proximity. The manual operation unit 52 includes a unit power supply 52a, an attachment state detection means (microswitch 52b) that detects the attachment state with respect to the touch operation terminal, and a short-range communicator 52c for the touch operation terminal. Therefore, even when the manual operation unit 52 is detached from the remote operation terminal (tablet terminal 51) and in close proximity, the connection between the remote operation terminal (tablet terminal 51) and the manual operation unit 52 can be maintained.

[0055] (5) When the attachment state detection means (microswitch 52b) detects that the touch operation terminal (tablet terminal 51) and the manual operation unit 52 are attached to each other, or when the detached proximity state is detected, a predetermined reaction action is set. For this reason, the detection signal from the attachment state detection means (microswitch 52b) can be used to set the reaction action.

[0056] (6) The ophthalmic device 10 is a subjective ophthalmic device equipped with a measurement head (refractor head 11) that measures subjective test items for the subject's eye E, and the manual operation unit 52 uses a jog dial 500 as a quantitative content operation means. Therefore, when a remote examination is performed using a subjective ophthalmic examination system, the examiner's input operation burden can be reduced by using a parameter input operation to the jog dial 500.

[0057] (7) The manual operation unit 52 performs a parameter input operation to set the test distance between the subject's eye E and the test target using the jog dial 500. Therefore, when a remote test is performed using the subjective optometry system, the test distance between the subject's eye E and the test target can be set by inputting parameters to the jog dial 500.

[0058] (8) The manual operation unit 52 performs parameter input operations to set optotype switching, auxiliary lens switching, mask switching, and data switching using the jog dial 500. Therefore, when a remote examination is performed using the subjective optometry system, optotype switching, auxiliary lens switching, mask switching, and data switching can be set by parameter input operations to the jog dial 500.

[0059] (9) The manual operation unit 52 performs a parameter input operation to set the amount of convergence and divergence adjustment using the jog dial 500. Therefore, when a remote examination is performed using the subjective optometry system, the amount of convergence and divergence adjustment can be set by inputting parameters to the jog dial 500.

[0060] (10) The manual operation unit 52 performs parameter input operations using the jog dial 500 to change the explanation display for the subject, select menu items, input numerical values ​​such as the patient number, and set the fixation light intensity, the target XY position, and the spherical refraction value [S], cylindrical refraction value [C], axial angle [A], and prism [P]. Therefore, when performing a remote examination using the subjective optometry system, various parameters other than (7) to (9) can be set by inputting parameters to the jog dial 500. [Example]

[0061] The ophthalmic apparatus 110 according to the second embodiment is an example of a subjective / objective ophthalmic apparatus that performs both subjective and objective ophthalmic examinations of the subject's eye E. In the following, as viewed from the subject S, the left-right direction is indicated by an arrow X, the up-down direction (vertical direction) is indicated by an arrow Y, and the direction perpendicular to the left-right direction and the up-down direction (depth direction) is indicated as the front-rear direction by an arrow Z.

[0062] A feature of the ophthalmic device 110 is that it can perform autorefraction and keratometry under binocular vision and subjective refraction testing with a single device. Furthermore, because the autorefractor, phoropter, and visual acuity chart are integrated, the time and effort required for moving between tests and the space required for equipment installation are eliminated, and the two tests can be performed in a smaller space than the area previously required for visual acuity testing. Furthermore, as with the first embodiment, it also supports remote operation, enabling visual acuity testing while maintaining social distance. The configuration of the ophthalmic device 110 according to the second embodiment will now be described with reference to FIGS. 7 and 8.

[0063] 7, the ophthalmologic apparatus 110 of the second embodiment includes a base 111 placed on the floor, an optometry table 112, a support 113, an arm 114, and a measurement head 120. An examinee facing the optometry table 112 places his or her forehead in contact with a forehead support 115 provided on the measurement head 120, and the ocular characteristics of the examinee's eye are measured.

[0064] The optometry table 112 is supported by a base 111, and its height is adjustable. A support column 113 stands upright in the Y direction from the rear end of the optometry table 112, and an arm 114 is provided on the upper part of the support column 113. The arm 114 supports the measurement head 120 by suspending it above the optometry table 112, and extends from the support column 113 in the Z direction. The arm 114 is attached to the support column 113 so as to be movable up and down.

[0065] A power supply unit 130 (controller) that includes a personal computer that performs overall control of the operations of each part of the ophthalmic apparatus 110 is attached below the optometry table 112. The power supply unit 130 is supplied with power from a commercial power source (not shown) via a power cable 130b.

[0066] The measurement head 120 is controlled by the power supply unit 130, and simultaneously measures the ocular characteristics of the subject's eye, such as dimensional information in the anterior-posterior direction of the subject's eye, the corneal shape of the subject's eye, and the refractive characteristics of the subject's eye, for both the left and right eyes. The measurement head 120 may also be used to perform any subjective test or any objective measurement other than those described above.

[0067] The measurement head 120 includes a left drive mechanism 121L and a right drive mechanism 121R provided on an attachment base portion not shown in the figure, a left eye measurement head 122L supported by the left drive mechanism 121L, and a right eye measurement head 122R supported by the right drive mechanism 121R.

[0068] The left eye measurement head 122L and the right eye measurement head 122R are provided in pairs to correspond to the left and right eyes to be examined, respectively, and are configured to be plane-symmetrical with respect to a vertical plane located midway between them in the X direction. Furthermore, the configuration of each drive unit of the left drive mechanism 121L that supports the left eye measurement head 122L and the configuration of each drive unit of the right drive mechanism 121R that supports the right eye measurement head 122R are configured to be plane-symmetrical with respect to a vertical plane located midway between them in the X direction.

[0069] The ophthalmic apparatus 110 of the second embodiment, configured as described above, measures the spherical refractive power, astigmatic refractive power, and astigmatic axis direction of the eyeball, as well as the radius of curvature of the corneal surface. Additionally, various subjective refractive visual acuity tests are performed. The ophthalmic apparatus 110 is characterized in that it can simultaneously measure the refractive power, corneal shape, and subjective measurements of both eyes, and can perform measurements using simultaneous auto-alignment of both eyes, enabling subjective measurements while maintaining binocular vision.

[0070] The remote operating device 50 of Example 2 is a device that transmits input information to the power supply unit 19 via wireless communication, and is used in a remote examination mode in which an examiner who is located at a distance of at least the social distance from the subject S operates the ophthalmic device 110.

[0071] As shown in Figure 8, the remote operation device 50, similar to Example 1, uses a tablet terminal 51 (touch operation terminal) having a touch panel display screen 51a and a manual operation unit 52 that works in conjunction with the tablet terminal 51.

[0072] The tablet terminal 51 is network-connected to the power supply unit 130 via cable-free wireless LAN communication. In the remote inspection mode, the touch panel display screen 51a displays a plurality of pieces of input operation selection information that are selected mainly by touch operation.

[0073] The manual operation unit 52 is detachably provided on the tablet terminal 51 and can be in an attached state or detached and placed in close proximity. The manual operation unit 52 has a jog dial 500 (quantitative content operation means) that allows the examiner to input quantitative content by moving his / her hand in a predetermined direction, as in Example 1. The detailed configuration of the manual operation unit 52 is the same as in Example 1, and therefore will not be illustrated or described here.

[0074] In the manual operation unit 52 of the second embodiment, the following parameter input operations are performed by manually operating the jog dial 500. (P1) The test distance between the subject's eye E and the test target is set. (P2) Set the optotype switching, auxiliary lens switching, mask switching, and data switching. (P3) Set the adjustment amount of the amount of convergence and divergence. (P4) Change the patient explanation display, select menu items, enter numerical values ​​such as the patient number, and set the fixation light intensity, target XY position, spherical refraction value [S], cylindrical refraction value [C], axial angle [A], and prism [P]. (P5) Fine-tune the XYZ position of the measurement part relative to the subject's eye during objective measurement, and set the adjustment amount of the amount of fogging during objective measurement.

[0075] Here, in (P5), the Z position may be the VD value (vertex distance). The X value may be the PD value (interpupillary distance) or a half PD value. Furthermore, in (P5), "fogging" refers to intentionally creating a myopic state and inhibiting the subject's ability to accommodate. The "amount of fogging" refers to the amount (strength) of fogging applied to the subject's eye, expressed as the fixation target presentation position (presentation distance). To adjust the amount of fogging, the fixation target presentation position is moved toward distance viewing (positive side) to increase the amount of fogging, and the fixation target presentation position is moved toward near viewing (negative side) to decrease the amount of fogging. Fogging tests are particularly used for hyperopic refraction tests and for examining the eyes of young subjects with significant accommodation.

[0076] The ophthalmologic apparatus 110 of the second embodiment has the following advantages in addition to the advantages (1) to (5) and (7) to (10) of the first embodiment.

[0077] (11) The ophthalmic device 110 is a subjective / objective ophthalmic device that measures subjective test items and objective test items for a subject's eye. The manual operation unit 52 uses a jog dial 500 as a quantitative content operation means, and the jog dial 500 is used to perform parameter input operations for fine-tuning the XYZ position of the measurement unit relative to the subject's eye during objective measurement and for setting the adjustment amount of the amount of fogging during objective measurement. Therefore, when performing a remote examination using the subjective / objective ophthalmic examination system, the parameter input operations to the jog dial 500 can be used to fine-tune the XYZ position of the measurement unit relative to the subject's eye during objective measurement and to set the adjustment amount of the amount of fogging during objective measurement. [Example]

[0078] The ophthalmic apparatus 210 according to the third embodiment is called an "autokeratorefractometer" and is an example of an objective ophthalmic apparatus that performs an objective eye examination of the subject's eye E. In the following, as viewed from the subject S, the left-right direction is indicated by an arrow X, the up-down direction (vertical direction) is indicated by an arrow Y, and the direction perpendicular to the left-right direction and the up-down direction (depth direction) is indicated as the front-rear direction by an arrow Z.

[0079] A distinctive feature of the ophthalmic device 210 is that it is equipped with 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.

[0080] Here, "REF (abbreviation for Refractometer)" refers to REF measurement of spherical refractive power, astigmatic refractive power, and astigmatic axis direction. "KRT (abbreviation for Keratometer)" refers to keratometry of corneal radius of curvature, corneal principal meridian direction, and corneal refractive power. "TONO (abbreviation for Tonometer)" refers to tonometry of intraocular pressure. "PACHY (abbreviation for Pachymeter)" refers to pachymetry of corneal thickness. The configuration of an ophthalmic apparatus 210 according to Example 3 will be described below with reference to Figures 9 and 10.

[0081] The ophthalmic apparatus 210 includes a face support unit 220 and a monitor unit 240. The entire system for ophthalmic measurement further includes an optical table 230 on which the ophthalmic apparatus 210 is placed, and a chair 250 on which the subject S sits.

[0082] The ophthalmologic apparatus 210 is placed on a top plate 231 of an optical table 230 , and includes a base portion 211 , a composite measuring head 212 (measuring head), and a cover member 213 .

[0083] An XYZ drive mechanism and drive circuit 216 (drive mechanism) is provided inside the base part 211 and between it and the composite measuring head 212. A control lever 2111, a USB input terminal 2114, and a LAN output terminal 2115 are provided outside the base part 211.

[0084] The XYZ drive mechanism / drive circuit 216 uses, for example, a stepping motor as a drive actuator, and drives the combined measurement head 212 in the XYZ directions, i.e., up and down, left and right, front and back, relative to the subject's eye E. The control lever 2111 is an operating lever used when manually driving the combined measurement head 212 in the XYZ directions relative to the subject's eye E during alignment adjustment, etc.

[0085] As shown in FIG. 10 , the combined measurement head 212 is disposed within a cover member 213 facing the subject's eye E, and performs measurements of multiple measurement items while observing an anterior eye image via an optical system. The combined measurement head 212 has a T / P measurement head 212a and an R / K measurement head 212b. The T / P measurement head 212a is configured with an optical system having an image sensor for capturing an anterior eye image, and performs tonoscopic and pachyscopic measurements for each of the left and right eyes of the subject S. The R / K measurement head 212b is disposed below the T / P measurement head 212a, is configured with an optical system having an image sensor for capturing an anterior eye image, and performs reflex and keratoscopic measurements for each of the left and right eyes of the subject S. Switching between the T / P measurement mode and the R / K measurement mode is performed by moving the combined measurement head 212 in the Y-axis direction, and switching between the left and right eyes is performed by moving the combined measurement head 212 in the X-axis direction.

[0086] The cover member 213 covers the combined measurement head 212, and when the subject S side of the ophthalmologic apparatus 110 is the front side, a T / P measurement window 2131 is arranged on the upper side of the front, and an R / K measurement window 2132 is arranged below the T / P measurement window 2131. A wide-angle camera 214 is arranged between the T / P measurement window 2131 and the R / K measurement window 2132. A printer cover 2133 and a printer cover open button 2134 are provided on the rear side of the cover member 213. Furthermore, a measurement window height mark 2135 for the R / K measurement window 2132 is set on the side of the cover member 213 facing the subject S.

[0087] The face support part 220 is connected and fixed to the front (front) of the base part 211 of the ophthalmologic apparatus 110, and shares the function of supporting the face of the subject S. The face support part 220 includes a base part 221, a chin rest part 222, a pair of supports 223, a forehead rest part 224, a drive mechanism 225, and a chin rest paper stopper pin 228. A height mark 227 for the subject's eye E is set on the side of the support part 223.

[0088] As shown in FIG. 10, the optical table 230 includes a top plate 231, a lifting mechanism 232, a table control unit 233, a power button 234, a lifting lever 235, and a caster base 236.

[0089] The monitor unit 240 is attached to the top of the rear side of the cover member 213, and has a touch panel display screen 241. The monitor unit 240 includes the display screen 241, a monitor cover member 242, and a monitor support portion 243.

[0090] The remote operating device 50 of Example 3 is a device that transmits input information via wireless communication to the power supply unit 217 built into the base part 211, and is used in a remote examination mode in which an examiner located at a distance of at least the social distance from the subject S operates the ophthalmic device 210.

[0091] The remote operation device 50 uses a tablet terminal 51 (touch operation terminal) having a touch panel display screen 51a and a manual operation unit 52 that cooperates with the tablet terminal 51 in combination.

[0092] The tablet terminal 51 is network-connected to the power supply unit 217 via cable-free wireless LAN communication. When performing fine alignment adjustment in the remote examination mode, the same face screen as the face screen centered on the eyes of the subject S displayed on the display screen 241 of the monitor unit 240 is displayed on the touch panel display screen 51a.

[0093] The manual operation unit 52 is detachably provided on the tablet terminal 51 and can be in an attached state or detached and placed in close proximity to the tablet terminal 51. The manual operation unit 52 has a control lever 530 (quantitative content operation means) that allows the examiner to input quantitative content by moving his / her hand in a predetermined direction.

[0094] In the manual operation unit 52 of the third embodiment, the following parameter input operations are performed by manually operating the control lever 530 (tilting direction and tilting time of the lever). (P6) Fine adjustment of the XYZ positions of the T / P measurement window 2131 and the R / K measurement window 2132 relative to the eye E is performed.

[0095] As described above, when a remote examination is performed, the manual operation unit 52 performs fine adjustment of the XYZ position of the measurement unit relative to the subject's eye by manually operating the control lever 530. At this time, as in the case of performing an examination in the close-up examination mode, the same face screen centered on both eyes of the subject S as that displayed on the display screen 241 of the monitor unit 240 is displayed on the touch panel display screen 51a. Therefore, the operating feel of the examiner who is accustomed to manually operating the control lever 2111 in the close-up examination mode can be realized in the remote examination mode.

[0096] The ophthalmologic apparatus 210 of the third embodiment has the following advantages in addition to the advantages (1), (4), and (5) of the first embodiment.

[0097] (12) The ophthalmologic apparatus 210 includes a measurement head (combined measurement head 212) that measures objective system examination items for the subject's eye E. The manual operation unit 52 uses a control lever 530 as a quantitative content operation means, and the control lever 530 is used to input parameters for fine adjustment of the XYZ position of the measurement unit relative to the subject's eye E. Therefore, when a remote examination is performed using the objective ophthalmology system, the XYZ position of the measurement unit relative to the subject's eye E can be finely adjusted by inputting parameters into the control lever 530. In addition, when performing fine alignment adjustment in the remote examination mode, the control lever 530 can be operated with the same operating feel as in the proximity examination mode.

[0098] 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 according to each claim in the scope of the claims.

[0099] In the first to third embodiments, an example has been shown in which one manual operation unit 52 is detachably attached to a tablet terminal 51 having a touch panel display screen 51a as the remote operation device 50. However, the specific configuration of the remote operation device 50 is not limited to the examples of the first to third embodiments.

[0100] For example, as shown in Fig. 11, a remote operation device 50 may be configured as three components arranged side by side, with two manual operation units 52, 52 detachably attached to the left and right peripheral end surfaces of a tablet terminal 51 having a touch panel display screen 51a. In this case, an examiner who is skilled at using both hands can improve operation efficiency compared to a device with a single manual operation unit. The manual operation unit 52 includes, for example, a jog dial 500, a first peripheral switch group 501, a power switch 503, and switches 504.

[0101] 12, a remote operation device 50 may be configured as a three-member vertical arrangement in which two manual operation units 52, 52' are detachably attached in the vertical direction to the upper and lower peripheral end faces of a tablet terminal 51 having a touch panel display screen 51a. The manual operation unit 52 includes, for example, a jog dial 500, a first peripheral switch group 501, and a power switch 503. The manual operation unit 52' includes, for example, switches 504.

[0102] In the first and second embodiments, an example is shown in which a jog dial 500 is used as the quantitative content operation means, and in the third embodiment, an example is shown in which a control lever 530 is used as the quantitative content operation means. However, the quantitative content operation means is not limited to the examples in which a jog dial or a control lever is used. In short, any quantitative content operation means may be used as long as it allows the examiner to input quantitative content by moving his / her hand in a predetermined direction.

[0103] For example, a jog lever 531 as shown in FIG. 13(a) may be used. A scroll button 532 as shown in FIG. 13(b) may be used. A trackball 533 as shown in FIG. 13(c) may be used. A control lever 534 as shown in FIG. 13(d) may be used. A jog dial 535 in the shape of a flat ring as shown in FIG. 13(e) may be used. A jog dial 536 that also functions as a cross key may be used as shown in FIG. 13(f).

[0104] In the first to third embodiments, an example was shown in which one means (jog dial 500, control lever 530) was used as the quantitative content operation means. However, as shown in Fig. 14, two means, a first operation lever 537 and a second operation lever 538, may be used as the quantitative content operation means. The arrows shown in Fig. 14 indicate the input operation directions of the first operation lever 537 and the second operation lever 538. Here, the two X-axis direction rotation arrows of the first operation lever 537 indicate the input operation directions of the two rotation rotations of the measurement unit with respect to the subject's eye.

[0105] In an example of a quantitative content operation means using two operation levers, a first operation lever 537 and a second operation lever 538, shown in FIG. 14, up and down inputs (Y-axis direction inputs) may be input by rotating the second operation lever 538 clockwise and counterclockwise. Also, as shown in FIG. 14, a dial knob 539 may be provided on the upper surface of the cylindrical base of the first operation lever 537, and the up and down inputs (Y-axis direction inputs) may be input by rotating the dial knob 539 clockwise and counterclockwise. Furthermore, as shown in FIG. 15, the quantitative content operation means may be a motion detection unit 540 that executes input processing of predetermined quantitative content associated with a detected motion (finger gesture) based on the motion (see JP 2020-141828 A, etc.).

[0106] In the first, second, and third embodiments, an example of a configuration in which the tablet terminal 51 and the manual operation unit 52 are detachably attached to each other has been shown as the remote operation device 50. However, the remote operation device may be configured such that the tablet terminal and the manual operation unit remain separate and cooperate with each other through near-field communication. The remote operation device may also be configured such that the tablet terminal and the manual operation unit are foldably connected together as shown in FIG. 6, for example. Furthermore, the tablet terminal and the manual operation unit may remain separate and cooperate with each other through input and output by connecting them with a USB cable.

[0107] In the first, second, and third embodiments, the tablet terminal 51 provided independently of the ophthalmologic apparatus is used as the touch operation terminal of the remote operation device 50. However, the touch operation terminal of the remote operation device may be, for example, the monitor unit 240 in the third embodiment shown in Fig. 9 that is detachable from the device body, and the monitor unit 240 detached from the device body serves as the touch operation terminal. In this case, the tablet terminal can be omitted.

[0108] In the first, second and third embodiments, the parameters (P1) to (P6) are input by an input operation using the quantitative content operation means. However, the parameters input by an input operation using the quantitative content operation means are not limited to the parameters (P1) to (P6).

[0109] For example, this includes adjusting the amount of vertical rotation in the ophthalmic apparatus 110 of Example 2 and adjusting the XYZ position of the robot arm. Here, "adjusting the amount of vertical rotation" refers to adjusting the amount of upward or downward rotation around the X axis in an ophthalmic apparatus having an X-axis rotation drive unit that rotates the measurement head around the axis of rotation (X axis) that passes through the center of rotation of the eyeball of the subject's eye and extends horizontally (see JP 2019-166037 A, etc.). In the ophthalmic apparatus of Example 2, the robot arm refers to a configuration consisting of multiple arm units extending from the frame unit to the measurement head and a rotation support mechanism provided at the joint position connecting the arm units. Furthermore, adjusting the XYZ position of the robot arm refers to adjusting the XYZ position of the measurement head by driving the rotation support mechanism (see JP 2021-019975 A, etc.).

[0110] In the first embodiment, an ophthalmic apparatus 10 is shown as an example of a subjective ophthalmic apparatus. However, the subjective ophthalmic apparatus may be any other subjective ophthalmic apparatus provided that it is equipped with a measurement head that measures subjective test items on the subject's eye. In the second embodiment, an ophthalmic apparatus 110 is shown as an example of a subjective / objective ophthalmic apparatus. However, the subjective / objective ophthalmic apparatus may be any other subjective / objective ophthalmic apparatus provided that it is equipped with a measurement head that measures subjective test items and objective test items on the subject's eye. In the third embodiment, an ophthalmic apparatus 210 is shown as an example of an objective ophthalmic apparatus. However, the objective ophthalmic apparatus may be any other objective ophthalmic apparatus provided that it is equipped with a measurement head that measures objective test items on the subject's eye.
