ABSTRACT:
An ophthalmic apparatus and a method for calculating internal refractive power distribution of an eye of an examinee, which allow easily evaluating refractive power distribution of a crystalline lens, an intraocular lens and the like. The ophthalmic apparatus has a unit which inputs respective measurement data on corneal refractive power distribution and whole refractive power distribution of the eye, the respective distribution referring to a reference axis, and a unit which obtains the internal refractive power distribution of the eye referring to the reference axis based on the inputted respective measurement data, obtains a prism component in the internal refractive power distribution with respect to the reference axis, and obtains internal refractive power distribution of the eye where the prism component is removed.
