Patent ID: 7762667

Claim:
A system for designing a customized ophthalmic lens or an ophthalmic lens capable of correcting high order aberrations, the system including a computer system that comprises: (a) a model eye design module for creating a computational model eye that reproduces aberrations of an eye of an individual, wherein the computational model eye comprises a lens-supporting surface having a corneal topography of the eye of the individual and a model retina having a curvature of the human retina and a model fovea comprising a lattice of pixels that represent photoreceptors, wherein the distance between the model fovea and the center of the lens-supporting surface is equal to a visual axial length of the human eye; (b) an optical design module for designing an optical model lens to compensate for the wavefront aberrations of the eye of the individual and to accommodate the corneal topography of the eye of the individual or an averaged corneal topography derived from population studies; (c) a lens-designing optimization module for performing an iterative optimization process comprising (1) determining visual performance information of the optical model lens with the computational model eye, (2) modifying the design of the optical model lens on the basis of said visual performance information to improve corrections of the aberrations of the eye, if the visual performance of said optical model lens is not optimal, and repeating steps (1) and (2), if necessary, until visual performance of a modified design of the optical model lens is optimized; and (d) a mechanical design module for generating a CAD output file containing parameters for making said customized ophthalmic lens or said ophthalmic lens capable of correcting high order aberrations, based on the optimized optical model lens.
