发明名称 Ophthalmic measurement apparatus
摘要 An ophthalmic measurement apparatus capable of obtaining refractive power containing a skew ray component, and further obtaining wavefront aberration from the refractive power with more ease and higher precision includes an optical system projecting slit light bundles onto a fundus of an examinee's eye and scanning the light bundles in predetermined first and second directions, an optical system with photodetectors placed in positions approximately conjugate with a cornea of the eye and placed in at least one meridian direction orthogonal to an optical axis of the photo-receiving optical system, and an arithmetic part obtaining, based on signals indicating phase differences from one of the photodetectors when photo-receiving the light bundles scanned in the first and second directions, refractive power in two directions at a corneal position corresponding to the photodetector position, and further obtains at least one of refractive power and a wavefront inclination by vector-synthesizing the obtained refractive power.
