摘要:
An ophthalmic measurement apparatus capable of outputting correction data (objective values) for a patients eye as approximate as possible to subjective values includes an optical system for projecting a measurement target onto a fundus and detecting an image of the target reflected therefrom using a photoelectric element so as to obtain measurement data on eye refractive power distribution or wavefront aberration, an optical system for photographing an anterior-segment including a pupil using an image-pickup element, a device which detects a size of a pupil area by image processing, and a device which obtains a spherical power, an astigmatic power, and an astigmatic axial angle based on the data within a given area smaller than the pupil area when the detected size is larger than a reference size, and obtains the three values based on the data within the pupil area when the detected size is smaller than the reference size.
