Patent ID: 8303746

Claim:
A method of manufacturing an ocular prosthesis comprising a posterior sclera portion and an anterior clear portion, the method comprising: providing an impression of an eye socket or an existing ocular prosthesis; scanning the impression or the existing ocular prosthesis to obtain scan data; generating a geometrical ocular prosthesis modeling object based on the scan data; transforming the geometrical ocular prosthesis modeling object to form a posterior modeling object and an anterior modeling object; modifying the posterior modeling object to include an iris table depression for insertion of an iris piece composed of a plurality of layers, the iris table depression including a base surface and a side surface extending from an outer edge of the base surface, at an angle at least substantially perpendicular to the base surface, and continuing to an outer surface of the posterior modeling object, wherein the iris table depression has substantially a same depth as a thickness of the iris piece such that a top surface of the iris piece is formed along a same plane as an edge of the outer surface of the posterior modeling object that is adjacent the iris table depression, wherein each layer of the iris piece is provided adjacent the side surface of the iris table depression such that an entire side surface of each layer is provided substantially a same distance from the side surface of the iris table depression; modifying the anterior modeling object to include a substantially level surface; fabricating the posterior scleral portion based on the modified posterior modeling object; fabricating the anterior clear portion based on the modified anterior modeling object; and forming the ocular prosthesis after fabrication of the posterior and anterior portions by joining the fabricated posterior sclera portion to the fabricated anterior clear portion.
