The operation lever 16 is provided on the gantry 13, and when it is tilted, the head unit 14 is moved in the front-rear and left-right directions, and when it is rotated about the axis, the head unit 14 is moved up and down. In the operation lever 16, a button switch 16a is disposed at the top, and acquisition of eye information is started by pressing the button switch 16a. The display unit 17 is provided in the head unit 14 and is configured by a liquid crystal display device (LCD monitor) as an example to be a touch panel type display screen. The operation by the lever 16 may be performed similarly on the touch panel of the display unit 17. In addition to the configuration described above, the ophthalmologic apparatus 10 is provided with a printer that prints measurement results in response to a measurement completion signal and an instruction from a measurer, and an output unit that outputs the measurement results to an external memory or server.

  The head unit 14 is provided with a control unit 18 that comprehensively controls each unit of the ophthalmologic apparatus 10. As shown in FIG. 2, the control unit 18 comprehensively controls the operation of the ophthalmologic apparatus 10 based on a program stored in the connected storage unit 19 or the built-in internal memory 18 a. The control unit 18 is connected to a measurement optical system light source, an alignment optical system light source, and sensors in an eye information acquisition unit 21 to be described later, and appropriately controls them. The control unit 18 is connected to an operation unit of an optical system necessary for measurement in the eye information acquisition unit 21 and appropriately drives (including movement) them. The control unit 18 is connected to the drive unit 12, the operation lever 16, and the display unit 17, and is acquired by the eye information acquisition unit 21 according to the operation performed on the operation lever 16 and the display unit 17 (its touch panel) and the above program. Eye information such as images and eye characteristics is appropriately displayed on the display unit 17. The control unit 18 appropriately controls the drive unit 12 and each of the light sources and each operation unit described above.

  The head unit 14 is provided with an eye information acquisition unit 21 that acquires eye information of the eye to be examined. The eye information includes the image of the eye to be examined, the image of the fundus of the eye to be examined, the tomographic image of the retina of the eye to be examined, the corneal endothelium image of the eye to be examined, the refractive power of the eye to be examined, the corneal shape of the eye to be examined, This refers to the intraocular pressure of the eye to be examined. The eye information acquisition unit 21 includes a fundus camera that captures a fundus image, a tomography apparatus (OCT) that captures a tomographic image of the retina, a specular microscope that captures a corneal endothelial image, a refractometer that measures refractive power, and a wavefront. A sensor, a keratometer for measuring the corneal shape, a tonometer for measuring intraocular pressure, and the like are configured singly or in combination.

  The eye information acquisition unit 21 includes an optical system such as a fixation projection system, an observation system, an alignment detection system, and a measurement system. Each optical system is appropriately provided with a light source, a sensor, a driving unit, and the like. The fixation projection system presents a fixation target to the eye to be examined and fixes the visual axis of the eye to be examined. The observation system captures the anterior segment of the eye to be examined and displays the image (observation image) on the display unit 17. This makes it possible to confirm the state of the eye to be examined and to acquire alignment information in the direction (XY direction) perpendicular to the optical axis based on the reference point (pupil, iris, etc.) in the image and the projected target image. Make it possible. The alignment detection system acquires alignment information in the optical axis direction (Z direction (working distance direction)) of the eye information acquisition unit 21 and alignment information in the XY directions. The alignment information is information used for alignment (positioning) with respect to the eye to be examined by the eye information acquisition unit 21. The measurement system irradiates the subject's eye with a light beam for acquiring the eye characteristic of the subject's eye and receives the reflected light to acquire the eye property.

  The ophthalmologic apparatus 10 is capable of performing a setting acquisition process (corresponding to steps S2 to S4 described later) that automatically performs alignment and acquires eye information of the eye to be examined under the control of the control unit 18. Yes. The setting acquisition process is predetermined, stored as a program in the storage unit 19 or the internal memory 18a, and executed by the control unit 18 operating each unit according to the program. In this setting acquisition process, the eye information acquisition unit 21 (its alignment detection system) and the drive unit 12 are operated, and the alignment of the eye information acquisition unit 21 (head unit 14) in the XYZ directions with respect to the eye to be examined is performed as described above. Is called. Thereafter, in the setting acquisition process, the eye information acquisition unit 21 is appropriately driven to acquire various types of eye information of the eye to be examined. When the ophthalmologic apparatus 10 cannot acquire various types of eye information of the eye to be examined by a predetermined setting acquisition process, the eye information on the eye to be examined is manually operated by the examiner by operating the operation lever 16 or the display unit 17. The acquisition unit 21 is aligned, and the eye information acquisition unit 21 can be driven to acquire various types of eye information of the eye to be examined (corresponding to step S12 and step S13 described later).

  In the ophthalmologic apparatus 10 according to the present disclosure, as illustrated in FIG. 2, a learning unit 31 is connected to the control unit 18. The learning unit 31 learns based on the operations of the eye information acquisition unit 21 and the drive unit 12 different from the setting acquisition process, that is, the operations (operation data) of the eye information acquisition unit 21 and the drive unit 12 manually. An acquisition process (learning acquisition process) is generated. The learning unit 31 may be configured using so-called artificial intelligence (AI (Artificial Intelligence)). The learning acquisition process is a method (solution) for acquiring eye information of the eye to be examined in a situation where eye information cannot be acquired by a predetermined setting acquisition process. In the first embodiment, the learning unit 31 acquires and accumulates operation data and situation data, and generates a learning acquisition process based on them. This will be described below.

  The status data indicates the status of the eye to be examined when the eye information cannot be acquired by the setting acquisition process. As an example, the information on the subject (the eye to be examined) and the observation image of the eye to be examined (stationary) acquired by the observation system And data obtained from an alignment detection system. Information on the subject (eye to be examined) includes, for example, the age and sex of the subject, a history of the subject's eye, etc., and is input using the operation lever 16 or the display unit 17 or connected to the ophthalmologic apparatus 10. Obtain from an external device.

  The operation data includes the operations of the eye information acquisition unit 21 and the drive unit 12 that are manually performed in a situation where the eye information cannot be acquired by the setting acquisition process, that is, the alignment operation (movement speed and movement of the eye information acquisition unit 21 performed by the examiner). Movement history, etc.) and eye information acquisition operation by the eye information acquisition unit 21 (focal length, gain, exposure amount, etc.). The operation data is associated with status data when the operation is performed. In the ophthalmologic apparatus 10, the eye information acquisition unit 21 and the drive unit 12 operate under the control of the control unit 18 in accordance with an operation on the operation lever 16 or the display unit 17. Therefore, such operation data (operation history) is acquired. It is possible.

  The learning unit 31 acquires each situation data and each action data, and appropriately analyzes the action in which the examiner manually acquires the eye information of the eye to be examined in a situation where the eye information cannot be acquired by the setting acquisition process based on the situation data and each action data. By doing this, a learning acquisition process, which is a method of acquiring eye information of the eye to be examined in a similar situation thereafter, is generated. As an example, the learning unit 31 can determine the situation by obtaining the feature points of each situation data. As this situation, for example, in the eye to be examined, eyeball shaking (nystagmus) occurs, blinking frequently, or an iris or corneal disease cannot be properly aligned. . These can be obtained from the observation image of the eye to be examined. In addition, in the case of a small pupil eye or a cataract eye, the eye information of the eye to be examined may not be acquired properly even though the alignment has been performed properly. This situation can be obtained from observation images of the eye to be examined and various measurement results.

  The learning unit 31 may generate a learning acquisition process from single situation data and action data, but more preferably, a similar situation is determined from a plurality of situation data, and a plurality of corresponding situations are determined. A learning acquisition process as an optimal operation is generated by obtaining a feature point of the operation data. In the following, some examples of manual operation for a specific situation and learning acquisition processing based on it will be described.

  If there is a misalignment between the center of the pupil and the apex of the cornea for the small pupil's eye, even if the alignment with respect to the apex of the cornea (corneal reflection image) is completed, the measurement light beam is vignetted by the iris of the eye to be measured. There are cases where it is not possible. In such a situation, it is assumed that the examiner has appropriately acquired the eye information by performing alignment based on the pupil even when a corneal reflection index image is obtained. Then, when the learning unit 31 determines that the eye to be examined is a small pupil and that there is a positional shift between the center of the pupil and the corneal apex, the learning unit 31 generates a learning acquisition process for switching the alignment reference to the center of the pupil. This determination can be made by setting a threshold value for the pupil diameter, setting a threshold value for positional deviation, and comparing whether or not the acquired pupil diameter and positional deviation are smaller than the threshold value. These threshold values may be set by learning by the learning unit 31 or may be set by an examiner.

  In situations where nystagmus is occurring or where there is an iris or corneal disease, the examiner may change the reference so that the eye information is acquired at the right time or the center of the pupil is changed to the corneal apex. It is assumed that eye information has been acquired or Then, when the learning unit 31 determines that nystagmus has occurred or that there is an iris or corneal disease, the learning unit 31 acquires the eye information in a timely manner, or changes the reference and performs alignment to obtain the eye information. A learning acquisition process to be acquired is generated.

  In a situation where blinking is frequent, the examiner tells the subject to close his / her eyes and then open the eye, and then obtains eye information at the appropriate timing. At this time, the examiner accumulates information obtained as described above as operation data by operating the operation lever 16 and the display unit 17. Then, when the learning unit 31 determines that blinking is frequent, the learning unit 31 generates a learning acquisition process for acquiring eye information in a timely manner. This operation can be executed by, for example, displaying on the display unit 17 that the eyes are opened when a signal is sent by voice or the like.

  In the case of a cataract eye or the like, an acquisition signal may not be obtained even if acquisition of eye information is started after alignment is completed. This may be because the measurement light beam cannot enter the eye to be inspected or the reflected measurement light beam does not return due to being blocked by the turbidity of the crystalline lens. In such a situation, the examiner obtains an acquisition signal when the turbid position of the crystalline lens can be identified and the alignment is shifted to the non-turbid part and the turbid position of the crystalline lens cannot be identified. It is assumed that the acquisition is performed by adjusting the alignment. Here, the opacity position can be identified from the transillumination image, for example, if the eye information acquisition unit 21 (ophthalmic apparatus 10) has a function of performing the transillumination method. Then, when the learning unit 31 determines that the eye is a cataract eye or does not obtain an acquisition signal even when the alignment is completed, the learning unit 31 acquires the eye information by shifting the alignment to a non-turbid portion based on the transillumination image. A learning acquisition process for generating eye information by adjusting alignment so as to obtain an acquisition signal is generated.

  In addition, the operation | movement performed manually with respect to each condition varies with an examiner, and is not limited to an above-described example. In addition to the examples listed above, there are many situations in which eye information cannot be acquired by the setting acquisition process, and the present invention is not limited to the above examples. And the learning acquisition process should just be produced | generated based on each operation | movement data corresponding to each situation data, The above-mentioned is an example.

  When the learning unit 31 generates a learning acquisition process, the control unit 18 stores the learning acquisition process (a program therefor) in the storage unit 19 or the internal memory 18a. The control unit 18 executes a preset setting acquisition process, and when the eye information cannot be acquired, executes a learning acquisition process as a solution corresponding to the situation. Note that a program for setting acquisition processing stored in the storage unit 19 or the internal memory 18a may be updated to a new setting acquisition processing including the generated learning acquisition processing.

  Next, in the ophthalmologic apparatus 10, an eye information acquisition process for acquiring eye information of the eye to be examined under the control of the control unit 18 will be described with reference to FIG. This eye information acquisition process is executed by the control unit 18 based on a program stored in the internal memory 18 a or the storage unit 19. Below, each step (each process) of the flowchart of this FIG. 3 is demonstrated. The flowchart of FIG. 3 is started when an operation for starting acquisition of eye information is performed in the ophthalmologic apparatus 10.

  In step S1, acquisition of the status data of the eye to be examined for which eye information is to be acquired is started, and the process proceeds to step S2.

  In step S2, the eye information acquisition unit 21 is aligned with the eye to be examined along the setting acquisition process, and the process proceeds to step S3.

  In step S3, it is determined whether or not the alignment has been properly performed. If YES, the process proceeds to step S4. If NO, the process proceeds to step S6. In step S3, in the case of NO, an error display indicating that alignment could not be performed is displayed on the display unit 17, and the alignment operation is stopped.

  In step S4, the eye information of the eye to be examined is acquired using the eye information acquisition unit 21 in accordance with the setting acquisition process, and the process proceeds to step S5.

  In step S5, it is determined whether or not eye information has been appropriately acquired. If YES, the process proceeds to step S9. If NO, the process proceeds to step S6. In step S5, in the case of NO, an error display indicating that eye information could not be acquired is displayed on the display unit 17.

  In step S6, it is determined whether or not there is a learning acquisition process corresponding to the situation data reaching here. If YES, the process proceeds to step S7, and if NO, the process proceeds to step S10. In step S6, whether or not there is a learning acquisition process corresponding to the situation data suitable for the situation where the alignment could not be properly performed in step S3 or the situation data suitable for the situation where the eye information could not be properly obtained in step S5. Judging. In step S6, if the learning acquisition process is not stored in the storage unit 19 or the internal memory 18a, it is determined as NO and the process proceeds to step S10.

  In step S7, a learning acquisition process corresponding to the situation data is executed, and the process proceeds to step S8.

  In step S8, it is determined whether or not eye information has been appropriately acquired. If YES, the process proceeds to step S9. If NO, the process proceeds to step S10. In step S8, in the case of NO, an error display indicating that the eye information could not be acquired by the learning acquisition process is displayed on the display unit 17.

  In step S9, the acquisition of the status data is terminated, and this eye information acquisition process is terminated. In step S9, since the eye information of the eye to be examined is automatically acquired by the eye information acquisition unit 21 in steps S2 to S8, the acquisition of the situation data started in step S1 is ended. This status data is stored in the internal memory 18a or the storage unit 19 as an indication of the status of acquisition. Note that this situation data is not used for generation of the learning acquisition process and may be discarded without being stored.

  In step S10, it is determined whether or not to move to a manual operation. If YES, the process proceeds to step S11. If NO, the eye information acquisition process is terminated. In step S10, it is determined whether to move to manual acquisition or to end acquisition by operating the operation lever 16, the display unit 17, or the like. In the operation from step S2 to S3, if the position of the eye information acquisition unit 21 (head unit 14) with respect to the eye to be examined cannot be determined even after a predetermined time has passed, the operation lever 16 or the display unit 17 is manually operated. When an operation indicating the acquisition or the end of the acquisition is performed, the process may be shifted to the determination in step S10 without waiting for the end of step S2 or the determination in step S3.

  In step S11, acquisition of operation data indicating manual acquisition of eye information executed in and after step S12 is started, and the process proceeds to step S12.

  In step S12, the eye information is manually acquired, and the process proceeds to step S13.

  In step S13, it is determined whether or not manual eye information acquisition is completed. If YES, the process proceeds to step S14. If NO, the process returns to step S12. The determination as to whether or not the acquisition has been completed is, for example, receiving an operation signal for printing out or transmitting the acquired eye information (its data) from the operation lever 16 or the display unit 17 or the acquisition has been completed. When an operation signal is received, it is determined that the operation has been completed, and in other cases, it is determined that the operation has not been completed.

  In step S14, the acquisition of the situation data and the operation data is terminated, and the eye information acquisition process is terminated. In step S14, since the manual acquisition of the eye information of the eye to be examined is completed, the acquisition of the status data that has been acquired in step S1 and the operation data that has been acquired in step S11 is completed. In step S <b> 14, the situation data and the operation data are associated with each other and stored in the internal memory 18 a or the storage unit 19, and are transmitted to the learning unit 31.

  Next, a learning process (learning method) in which the learning unit 31 generates a learning acquisition process in the ophthalmologic apparatus 10 will be described with reference to FIG. Below, each step (each process) of the flowchart of this FIG. 4 is demonstrated. The flowchart of FIG. 4 is started when the learning unit 31 acquires operation data and situation data.

  In step S21, the operation data and situation data are analyzed, and the process proceeds to step S22. In step S21, the acquired operation data and situation data are analyzed. If there is operation data and situation data acquired before the start of the current flowchart, the analysis is performed by taking them into account.

  In step S22, the learning acquisition process is generated, and the process proceeds to step S23. In step S22, what kind of situation is determined, and a learning acquisition process indicating a method for acquiring eye information of the eye to be examined in the determined situation is generated. In step S22, depending on the contents and number of motion data and situation data, there are cases where a learning acquisition process can be generated and cases where it cannot be generated.

  In step S23, it is determined whether or not a learning acquisition process has been generated. If YES, the process proceeds to step S24. If NO, the learning process ends.

  In step S24, a learning acquisition processing program generated by learning the measurement processing algorithm for special eyes is stored, and the learning processing is terminated. In step S <b> 24, the learning unit 31 transmits a learning acquisition process to the control unit 18. The control unit 18 stores the learning acquisition process generated in step S23 in the storage unit 19 or the internal memory 18a.

  Next, in the ophthalmologic apparatus 10, an example of the operation of the eye information acquisition process of the control unit 18 and the learning process of the learning unit 31 described above when acquiring eye information of the eye to be examined will be described. The examiner fixes the subject's face with the face receiving unit 15 and starts obtaining desired eye information (eye information obtaining process shown in the flowchart of FIG. 3). The ophthalmologic apparatus 10 proceeds to step S 1 → S 2 → S 3 → S 4 → S 5 → S 9 in a situation where automatic acquisition by the setting acquisition process is possible, and acquires eye information. The ophthalmologic apparatus 10 proceeds from step S1 to S2 to S3 (→ S4 to S5) to S6 in a situation where automatic acquisition by the setting acquisition process is not possible, and a learning acquisition process corresponding to this situation is stored. Determine whether or not. Here, in a situation where the learning acquisition process is not stored (a situation where the learning acquisition process cannot be obtained), the process proceeds to step S6 (→ S7 → S8) → S10, and the process is switched to manual acquisition and the process proceeds to step S11. Then, the ophthalmologic apparatus 10 repeats steps S12 → S13 as appropriate according to the manual operation by the examiner, and proceeds to step S14 when the manual acquisition of the eye information is completed. As a result, the ophthalmologic apparatus 10 transmits, from the control unit 18 to the learning unit 31, situation data indicating the situation data and operation data manually performed on the situation data in a situation where automatic acquisition is not possible.

  Then, the learning unit 31 executes the learning process shown in the flowchart of FIG. 4, proceeds from step S <b> 21 to S <b> 22, and performs learning acquisition process generation work based on the transmitted situation data and operation data. If it is generated, the process proceeds from step S22 to S23 to S24, and the control unit 18 stores the learning acquisition process.

  Then, since the control part 18 can perform the learning acquisition process memorize | stored after this, if it is judged that it is the above-mentioned situation where automatic acquisition was not possible, step S1-> S2-> S3 (-> S4-> S5) ) → After proceeding to S6, since the corresponding learning acquisition process is stored, the process proceeds to step S7 → S8, and the operation similar to the operation manually performed by the examiner is automatically performed by the learning acquisition process. The eye information is acquired.

  As described above, the ophthalmologic apparatus 10 accumulates the situation data and the operation data every time the situation where the automatic acquisition by the setting acquisition process cannot be performed, performs the generation process of the learning acquisition process based on them, and generates the generated learning acquisition. Remember the process. For this reason, the ophthalmologic apparatus 10 is automatically acquired by the learning acquisition process when the same situation (similar special eye) occurs next even in a situation where it cannot be automatically acquired by the setting acquisition process and is manually acquired. The possibility that you can come out. And the ophthalmologic apparatus 10 can expand the situation which can acquire the eye information of the eye to be examined automatically by the learning acquisition process by accumulating more situation data and operation data.

  The ophthalmologic apparatus 10 of Embodiment 1 of the ophthalmologic apparatus according to the present disclosure can obtain the following functions and effects.

  If the ophthalmologic apparatus 10 cannot perform automatic acquisition for performing a predetermined setting acquisition process and a situation where manual acquisition different from the setting acquisition process occurs, the eye information acquisition unit 21 at that time and Based on the operation data indicating the operation of the drive unit 12, the learning unit 31 learns a measurement processing algorithm for the special eye and generates a learning acquisition process. Then, the control unit 18 stores the generated learning acquisition process in the storage unit 19 or the internal memory 18a. For this reason, the ophthalmologic apparatus 10 can be automatically acquired by the learning acquisition process corresponding to the special eye learned when the same situation is acquired next by manually acquiring in the situation that cannot be acquired by the setting acquisition process. Sex comes out. Therefore, the ophthalmologic apparatus 10 can expand the situation where the eye information of the eye to be examined can be acquired automatically.

  In addition, when the ophthalmologic apparatus 10 receives a signal indicating that the eye information of the eye to be examined has been successfully acquired by the operation of the eye information acquisition unit 21 and the drive unit 12 performed manually, the control unit 18 causes the learning unit 31 to Get motion data. For this reason, the ophthalmologic apparatus 10 accumulates only the operation data in a situation where the acquisition of the eye information of the eye to be inspected manually after the automatic acquisition of the eye information of the eye to be inspected is successful. Only useful data can be acquired by the learning unit 31.

  Further, in the ophthalmologic apparatus 10, the learning unit 31 acquires situation data indicating a situation in which eye information cannot be acquired by the setting acquisition process, and generates a learning acquisition process by associating the operation data with the situation data. The ophthalmologic apparatus 10 selects the control mode of the eye information acquisition unit 21 and the drive unit 12 according to the condition of the eye to be examined by following the learning acquisition process generated by the control unit 18 corresponding to the special eye. In particular, when the ophthalmologic apparatus 10 according to the first embodiment executes automatic acquisition, when the situation is set as the generated learning acquisition process, the ophthalmologic apparatus 10 acquires the eye information of the eye to be examined in the situation (learning). Since the acquisition process is executed, the time required for automatic acquisition can be reduced.

  The ophthalmologic apparatus 10 stores the generated learning acquisition process in the storage unit 19 or the internal memory 18a separately from the preset setting acquisition process. For this reason, the ophthalmologic apparatus 10 is basically configured to perform a common setting acquisition process regardless of the learning state by the learning unit 31, so that maintenance and management can be facilitated.

  The ophthalmologic apparatus 10 includes an observation image of the anterior segment in the condition (situation data) of the eye to be examined. For this reason, the ophthalmologic apparatus 10 can automatically and appropriately align and acquire a situation where the eye to be examined is a small pupil and the pupil center and the corneal apex are misaligned.

  The ophthalmologic apparatus 10 includes the eye characteristics of the eye to be examined in the situation (situation data) of the eye to be examined. For this reason, the ophthalmologic apparatus 10 can automatically acquire, for example, a subject eye having a disease in the cornea or the iris.

  Since the ophthalmologic apparatus 10 generates a learning acquisition process in accordance with operation data manually performed by the examiner, the operation can be performed in accordance with the manner of the examiner who uses this apparatus. Can be customized (customized).

  If the ophthalmic apparatus 10 fails to automatically acquire the eye information of the eye to be examined, the control unit 18 causes the learning unit 31 to acquire the operation data. Therefore, only the operation data in the situation where the automatic acquisition has failed is accumulated. Only the useful data can be acquired by the learning unit 31.

  The ophthalmologic apparatus 10 includes not only the case where the acquisition of the eye information of the eye to be examined is unsuccessful (its situation data) but also the processing according to the learning acquisition processing as well as the processing according to the setting acquisition processing. Therefore, the learning acquisition process can be deepened, and the situation in which the eye information of the eye to be examined can be automatically acquired can be further expanded.

  Therefore, in the ophthalmologic apparatus 10 as an embodiment of the ophthalmologic apparatus according to the present disclosure, it is possible to expand the situation where the eye information of the eye to be examined can be automatically acquired.

  The ophthalmologic apparatus of the present disclosure has been described based on the first embodiment. However, the specific configuration is not limited to the first embodiment and does not depart from the gist of the invention according to each claim in the claims. As long as the design is changed or added, it is allowed.

  For example, in the first embodiment, the learning acquisition process is generated based on the operation data and the situation data. However, the learning acquisition process may be generated based only on the operation data, and is not limited to the configuration of the first embodiment. This is because, for example, when the examiner performs an operation different from the predetermined setting acquisition process on the eye information acquisition unit 21 or the drive unit 12 regardless of the situation, based on the operation data indicating the operation. Generating a learning acquisition process.

  In the first embodiment, learning acquisition processing is appropriately stored inside the ophthalmologic apparatus 10. However, the ophthalmologic apparatus 10 may be configured to store a learning acquisition process generated by the learning unit (31) of another ophthalmologic apparatus (10) via a network or the like. In this way, it is possible to share various methods of acquiring examiners using other ophthalmologic apparatuses (10) as big data, and there are few skilled persons in the facility having the ophthalmologic apparatus 10. In addition, the situation where the eye information of the eye to be examined can be acquired automatically can be further expanded.

  Further, in the first embodiment, the learning acquisition process is generated based on the operation data and the situation data when the eye information is successfully acquired by the operations of the eye information acquisition unit 21 and the drive unit 12 that are manually performed. However, the learning acquisition process may be generated based on operation data or situation data when eye information acquisition fails even manually. In this case, for example, it is possible to determine a situation in which acquisition is not possible by automatic acquisition or manual acquisition by setting acquisition processing, and by displaying on the display unit 17 or the like that such a situation is not possible, It is possible to prevent useless acquisition attempts for the eye to be examined. The determination that the eye information acquisition has failed even manually is received from the operation lever 16 or the display unit 17, for example, an operation signal for switching to the other eye to be examined during the execution of the acquisition, or reset. This can be done by receiving the operation signal.
