Abstract
A technology for achieving a reduction in size of an ophthalmic apparatus capable of performing a plurality of kinds of measurements performed before cataract surgery is provided. An ophthalmic apparatus is described that includes a refractive power measurement unit and an eyeball information measurement unit. The refractive power measurement unit is configured to project light from a light source onto a subject's eye and detect returning light thereof to determine refractive power of an ocular optical system of the subject's eye. The eyeball information measurement unit is configured to project light from the same light source onto the subject's eye and detect returning light thereof to determine eyeball information representing structure of the subject's eye.
