Patent ID: 7111938

Claim:
A method for designing a customized ophthalmic lens, the method comprising the steps of: (1) providing a set of characteristic data of an eye of an individual, wherein said set of characteristic data comprises wavefront aberrations of the eye and corneal topography; (2) creating a computational model eye that reproduces the wavefront aberrations of the eye of the individual, wherein the computational model eye comprises a lens-supporting surface having the corneal topography of the eye of the individual and a model retina having a model fovea comprising a lattice of pixels that represent photoreceptors and can be used to perform bitmap image analysis and/or ghost image analysis of an optical model lens to be evaluated, 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; (3) designing an optical model lens which is capable of compensating for the wavefront aberrations of the eye, wherein said optical model lens has an anterior surface and an opposite posterior surface; (4) evaluating the visual performance of said optical model lens with the computational model eye; (5) obtaining visual performance information of said optical model lens; (6) modifying the design of said 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; (7) repeating steps (4) to (6), if necessary, until the visual performance of said optical model lens is optimal; and (8) transforming the optimized optical model lens into a set of mechanical parameters for making said customized ophthalmic lens.
