<P>PROBLEM TO BE SOLVED: To measure an anterior eye part with high reproducibility. <P>SOLUTION: An anterior eye part measurement apparatus includes: a projection optical system for projecting light emitted from a light source toward the anterior eye part of a subject eye and forming an optical cutting surface on the anterior eye part; and a light reception optical system having a detector for receiving anterior eye part scattering light to be acquired by scattering on the optical cutting surface in the anterior eye part. Then, the apparatus forms an anterior eye part cross sectional image, on the basis of a detection signal from the detector, processes the cross sectional image, and measures the anterior eye part. The apparatus includes: a deviation detection means for detecting a positional deviation in a direction to be orthogonal to the optical cutting surface between a position where the cross sectional image is actually acquired and a desired position; and a correction means for correcting a measurement result with respect to the anterior eye part, on the basis of the detection result of the deviation detection means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
