Abstract:
An ophthalmic apparatus having measurement means for inspection or measurement, that brings said measurement means into a predetermined positional relationship relative to an eye to be examined, comprising:moving means that moves said measurement means relatively to the eye in vertical and lateral directions;alignment target projecting optical system that projects plural alignment targets onto the periphery of a cornea of the eye under the condition where a measurement axis of said measurement means approximately coincides with a visual axis of the eye;alignment target detecting optical system that detects target images formed by said alignment target projecting optical system;memory in which positional relationships of the detected target images are stored;judging means having a program that can judge a direction to move by comparison of the stored positional relationships with number and positional relationships of the detected target images when a number of the detected target images is smaller than a number of the projected alignment targets; anda control unit that gives a driving signal to said moving means based on a result judged by said judging means.
