  • Surface design method
    Patent number: 6419359
    Abstract: A surface design method for designing refractive optical devices, and the optical devices themselves, using a wave transform analysis technique to control aberrations and produce a device with more precise refractive properties in response to topographical data derived from the corneal surface. The method can be used to produce other output surfaces.
