CORRECTION OF HIGHER ORDER ABERRATIONS IN INTRAOCULAR LENSES

摘要

A method of correcting higher order aberration in IOL(IntraOcular Lenses) is provided to consider more than one eyeball variable, eyeball axis length or the variation of asphericity of cornea in a constant group of patients for IOL operation. According to a method for designing IOL(IntraOcular Lenses) treating the variation in more than one eyeball parameter of patient eyes of one group, more than one eye model able to vary over the range where the eyeball parameter is generated by a group is assured. A number of IOL designs are evaluated for visual performance of the eye of the patient group by using the eye model. An IOL design providing optimum fitness to the visual performance over at least a part of the range generated by the group is selected.
