An ophthalmic measurement apparatus which measures wavefront aberration of a patients eye with high accuracy includes an irradiation optical system including a high-coherence measurement light source, a photo-receiving optical system including a light dividing element and a photodetector, a measurement light deflector placed in a position on an optical path of the irradiation optical system and not on that of the photo-receiving optical system, a memory storing deflection information and a pattern photo-received on the photodetector and associated with the information, and a control unit which drives the deflector to form patterns in different deflection states, controls the photodetector to photo-receive the patterns, reads out from the memory the information and the pattern, corrects the patterns based on their corresponding information by an amount of displacement of the read-out pattern with respect to a reference pattern, and performs addition to the corrected patterns so as to calculate the wavefront aberration.
