Claims (6)

A measurement unit having a corneal thickness measurement means for optically measuring the corneal thickness at an arbitrary measurement point of the subject's eye in a non-contact manner;
Moving means for moving the measuring unit in the vertical and horizontal directions with respect to the subject's eye;
An imaging optical system for imaging the anterior segment of the subject's eye;
Display means for displaying an anterior segment image of the subject's eye imaged by the imaging optical system;
Measurement point setting means for setting a plurality of measurement points on the subject's eye cornea in order to measure the corneal thickness distribution of the subject's eye;
Guidance means for guiding alignment to the eye of the subject using the moving means for aligning the measurement optical axis of the corneal thickness measurement means with each measurement point set by the measurement point setting means;
Corneal thickness distribution information acquisition means for acquiring the corneal thickness distribution information of the subject's eye by associating the measurement result measured at each measurement point with the measurement position by the corneal thickness measurement means,
