PROBLEM TO BE SOLVED: To obtain good prescription results irrespective of the method of measuring ocular axial length.SOLUTION: The ophthalmic device includes: an light interference ocular axial length measurement device for obtaining a first ocular axial length value by light interference an ultrasonic ocular axial length measurement device for obtaining a second ocular axial length value by ultrasonic waves an imaging optical system in which an imaging element takes a first corneal reflected image in a first projection optical system as well as a second corneal reflected image in a second projection optical system and a computing means for calculating the first and second ocular axial length values based on output signals from the ultrasonic ocular axial length measurement device and the optical interference ocular axial length measurement device, as well as for calculating the corneal curvature of a subject eye based on the first and second corneal reflected images taken by the imaging element.
