Claim One:
1. An ophthalmologic apparatus comprising: an examination optical system configured to carry 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; and a controller configured to control the driver based on the three-dimensional position to relatively move the examination optical system and the supporting part in order that a position of the examination optical system and the three-dimensional position of the eye match each other in two axis directions both perpendicular to an optical axis direction of the examination optical system, and a distance between the examination optical system and the eye becomes a predetermined working distance in the optical axis direction, wherein the analyzer comprises: a characteristic position specifying part configured to analyze the two or more photograph images to specify characteristic positions in the photograph images that correspond to a predetermined characteristic part of the anterior eye part; and a three-dimensional position calculating part configured to calculate, as the three-dimensional position of the eye, a three-dimensional position of the characteristic part based on positions of the two or more imaging parts and the characteristic positions in the two or more photograph images.
