Patent ID: 7258443

Claim:
An ophthalmologic apparatus comprising: alignment light beam projection means for projecting an alignment light beam onto a cornea of an eye to be examined: alignment light beam detection means for detecting the cornea reflected light of said alignment light beam; a plurality of illumination means for illuminating the anterior ocular of the eye to be examined; image sensing means for sensing the anterior ocular of the eye to be examined; pupil position detection means for detecting the pupil position of the eye to be examined from the image of the anterior ocular sensed by said image sensing means, cornea reflected image interval detection means for detecting an interval between the plurality of cornea reflected images of said illumination means; first position alignment means for detecting the position of the eye to be examined by the cornea reflected light detected by said alignment light beam detection means to thereby effect the position alignment of an eye examining portion and the eye to be examined; memory means for storing therein as a reference interval said interval between said plurality of cornea reflected images detected by said cornea reflected image interval detection means when the position alignment by said first position alignment means has been completed; second position alignment means for aligning said eye examining portion with said pupil position detected by said pupil position detection means; and third position alignment means for detecting the positional displacement of the eye to be examined in a front to rear direction on the basis of a relation between said interval detected by said cornea reflected image interval detection means and said reference interval stored in said memory means to thereby effect the position alignment of said eye examining portion and the eye to be examined in the front to rear direction.
