Abstract: An ophthalmic apparatus obtains naked-eye wavefront aberration data of an examinee's eye measured by an aberration measuring unit, and calculates first corrected wavefront aberration data intended for a prescription with a first correction power based on the naked-eye wavefront aberration data and the first correction power and generates a first evaluation index based on the first corrected wavefront aberration data. The ophthalmic apparatus further calculates second corrected wavefront aberration data intended for a prescription with a second correction power different from the first correction power in at least one of spherical power, astigmatic power, and astigmatic axis angle based on the naked-eye wavefront aberration data and the second correction power, and generates a second evaluation index based on the second corrected wavefront aberration data. The ophthalmic apparatus then displays the first and second evaluation indexes selectively or in parallel on a monitor.

Abstract: An ophthalmic measurement device to simulate a retinal image of an examinee's eye includes an ocular aberrometer for measuring an aberration of the eye and a calculation control unit for analyzing aberration data obtained by the ocular aberrometer on the naked eye. The calculation control unit calculates subjective correction data intended for a prescription based on a subjective value by obtaining the difference in each meridian direction between a refraction value in the aberration data and a new subjective value of the eye as obtained by a subjective optometry device, obtains a second polynomial equation wherein the coefficient that represents the refraction value among the coefficients of a first polynomial equation used for approximating the aberration data is replaced with a coefficient corresponding to the subjective correction data, back-calculates the aberration data by using the second polynomial equation, and generates a simulation image based on the back-calculated aberration data.
