ABSTRACT:
A contact lens for use with an asymmetric aspherical cornea. The lens includes an anterior surface, a posterior surface and a base. The posterior and anterior surfaces each include a center optical portion and an outer peripheral corneal portion. The posterior surface is divided into a plurality of local surface segments by a plurality of radially extending boundaries that originate from a common center point on the posterior surface of the lens. Each of the local surface segments conforms to the shape of a corresponding local surface portion of the cornea that lies under the respective lens local surface segment when the lens is worn on the eye.
