发明名称 OPHTHALMIC MEASUREMENT DEVICE, AND OPHTHALMIC MEASUREMENT SYSTEM EQUIPPED WITH OPHTHALMIC MEASUREMENT DEVICE
摘要 [Problem] To enable a good simulation to be performed. [Solution] This ophthalmic measurement device is used to simulate a retinal image of an eye to be examined, and is equipped with 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 with the assumption of a prescription on the basis of a subj ective 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 that corresponds to the subjective correction data, back-calculates the aberration data by using the second polynomial equation, and generates a simulation image on the basis of the back-calculated aberration data.
