Patent ID: 8057035

Claim:
A method of manufacturing a contact lens for use in a corneal refractive therapy program that comprises: evaluating a cornea of a patient and generating a set of data elements related to fitting a contact lens having a central zone, a connecting zone adjacent to the central zone, and a peripheral zone adjacent to the connecting zone to a patients cornea for imparting a compression force to alter curvature of the cornea, providing a computer system, where the set of data elements are input, wherein the characteristics in each of central and peripheral zones are independent from one another, and the connecting zone is modeled to transition between said central and peripheral zones, processing the set of data elements and generating lens cutting data for a computer lathe, and controlling a computerized lathe using the lens cutting data to form a contact lens that is designed to fit the central zone and peripheral zone onto the patient's cornea in a predetermined manner, wherein the contact lens reshapes the cornea to treat visual deficiencies.
