Abstract:
An ophthalmic apparatus includes an imaging optical system for imaging an anterior segment image including a pupil of an examinee's eye, a pupil detection unit for detecting a size of the pupil of the examinee's eye based on the imaged result by the imaging optical system, and an output unit configured to obtain size information of a far vision zone and a near vision zone for a multifocal intraocular lens and output the obtained size information and the size of the pupil detected by the pupil detection unit to be comparable. Accordingly, applicability of the multifocal intraocular lens can be determined accurately and easily.
