Patent ID: 7780293

Claim:
A method for manufacturing customized contact lenses, the method comprising the steps of: (1) analyzing eyes of each of the individuals from a population to obtain a set of characteristic data comprising aberrations and corneal topography; (2) compiling population statistics of aberrations and corneal topographies; (3) creating a plurality of computational model eyes, each of which generates averaged aberrations representing statistically one of a plurality of nominal segments of the population, wherein each of plurality of computational model eyes comprises a lens-supporting surface having an averaged corneal topography for one of a plurality of nominal segments of the population and a model retina having 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; (4) designing a plurality of optical model lenses each of which accommodates the averaged corneal topography of the eyes of one of the plurality of nominal segments of the population and corrects the averaged aberrations of the eyes of one of the plurality of nominal segments of the population; (5) optimizing optical designs of the plurality of the optical model lenses with one of the plurality of the computational model eyes; (6) transforming the plurality of the optimized optical model lenses into a plurality of sets of mechanical parameters each for making one contact lens; (7) creating one stock keeping unit (SKU) for each of each of the contact lenses; and (8) manufacturing said ophthalmic lenses having a specific stock keeping unit (SKU).
