Abstract
An ophthalmic apparatus includes a first optical system for acquiring information regarding an eye refractive power of a subject eye based on reflection light of measurement light reflected from a fundus of the subject eye, a second optical system for acquiring anterior segment information regarding a shape of an anterior segment of the subject eye, and a calculation controller that acquires an axial length of the subject eye based on an on-surface eye refractive power, which is the eye refractive power on a cross section on which an optical axis of the first optical system is arranged and the anterior segment information regarding the cross section.
