Patent ID: 6878314

Claim:
A method for cast molding a plurality of toric contact lenses having a desired astigmatism-correcting characteristic, the process comprising: (a) providing a pair of casting cup halves having the astigmatism-correcting characteristic defined by an assembled relative rotational alignment of one casting cup half with respect to the other casting cup half; (b) filling one of said casting cup halves with liquid monomer material; (c) reassembling the casting cup halves under a precisely controlled motion while maintaining the rotational alignment between the casting cup halves; (d) curing said liquid monomer material thereby molding the material into a toric contact lens having the desired astigmatism-correcting characteristic; (e) separating said casting cup halves such that the toric contact lens remains with one of the casting cup halves; (f) holding the casting cup half having the toric contact lens; (g) applying an iris print to the toric contact lens; (h) locating the casting cup half with the toric contact lens; (i) passing the toric contact lens to a video inspection station; and (j) verifying the iris print applied to the toric contact lens by video inspection.
