Abstract
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.
