Ophthalmologic apparatus

摘要

An ophthalmologic apparatus includes an examination optical system, drive part, two or more imaging parts, analyzer, storage, position corrector, and controller. The examination optical system examines an eye. The drive part moves the examination optical system. The imaging parts substantially simultaneously photograph the anterior segment of the eye from different directions. The analyzer analyzes two or more photographic images captured substantially simultaneously by the imaging parts to obtain a three-dimensional position of the eye. The storage stores correction information in advance. The correction information is acquired based on optical properties of eyeballs, and used to correct the position of the eye in the optical axis direction of the examination optical system. The position corrector corrects the three-dimensional position obtained by the analyzer based on the correction information. The controller controls the drive part based on the three-dimensional position corrected to move the examination optical system.

主权项

1. An ophthalmologic apparatus comprising:
an examination optical system configured to be used to examine an eye; a drive part configured to move the examination optical system; two or more imaging parts configured to substantially simultaneously photograph an anterior segment of the eye from different directions; an analyzer configured to analyze two or more photographic images captured substantially simultaneously by the two or more imaging parts to obtain a three-dimensional position of the eye; a storage configured to store correction information, acquired in advance based on optical properties of an eyeball, for a position of an eye in an optical axis direction of the examination optical system; a position corrector configured to correct the three-dimensional position obtained by the analyzer based on the correction information; and a controller configured to control the drive part based on the three-dimensional position corrected to move the examination optical system.
