Ophthalmologic apparatus

摘要

An ophthalmologic apparatus which is capable of preferably executing position matching between an eye and optical system is provided. An ophthalmologic apparatus of an embodiment includes an examination optical system, supporting part, driver, two or more imaging parts, analyzer and controller. The examination optical system is used for an examination of the eye. The supporting part supports a face of a subject. The driver moves the examination optical system and the supporting part relatively and three-dimensionally. The two or more imaging parts substantially simultaneously photograph an anterior eye part of the eye from different directions. The analyzer obtains a three-dimensional position of the eye by analyzing two or more photograph images acquired by the two or more imaging parts substantially simultaneously. The controller controls the driver based on the three-dimensional position to relatively move the examination optical system and the supporting part.

1. An ophthalmologic apparatus comprising:
an examination optical system configured for carrying out an examination of an eye; a supporting part configured to support a face of a subject; a driver configured to move the examination optical system and the supporting part relatively and three-dimensionally; two or more imaging parts configured to substantially simultaneously photograph an anterior eye part of the eye from different directions; an analyzer configured to obtain a three-dimensional position of the eye by analyzing two or more photograph images acquired by the two or more imaging parts substantially simultaneously; a controller configured to control the driver based on the three-dimensional position to relatively move the examination optical system and the supporting part, the driver comprises a first driver configured to move the examination optical system three-dimensionally, the controller controls the first driver based on the three-dimensional position so as to align an optical axis of the examination optical system with an axis of the eye and adjust a distance between the eye and the examination optical system to a preset working distance, the driver comprises a second driver configured to move the supporting part, and the controller controls the second driver based on the analysis results of the two or more photograph images from the analyzer to move the supporting part, and further comprising an approach detector configured to detect a state in which the subject approaches the supporting part, wherein when the approach is detected, the controller controls the two or more imaging parts to execute substantially simultaneous photography.
