Abstract: A method for tracking multiple SKUs of contact lenses in a manufacturing line comprising the steps of: a) molding a plurality of contact lenses, b) providing a plurality of carriers each having a carrier indicator, c) inspecting each contact lens to determine information relating to its prescription, d) transferring each lens to a carrier, e) reading the carrier indicator of the carrier of step d) and f) storing in machine-accessible memory the information associated with the carrier indicator of the carrier of step (e) and the information relating to the lens for step (c).

Abstract: A mold is disclosed for making rotationally asymmetric contact lenses. The mold comprises a first concave or convex surface that is rotationally asymmetric for forming the surface of the contact lens thereagainst, a second concave or convex surface opposed to the first surface that is also rotationally asymmetric, and a segment of the mold between the first and second surfaces having a substantially uniform thickness.

Abstract: A method of injection molding contact lens molds for cast molding contact lenses having a rotationally asymmetric lens surface, and apparatus for carrying out the method, are disclosed.
