Abstract
Fabrication of contact lenses whereby the yield of lenses removed from plastic casting molds is significantly increased. In fabricating contact lenses where a lens is initially formed in a plastic casting mold, the mold is compressed to a degree sufficient to initiate permanent deformation of the mold material, in progressive steps, incrementally decreasing in diameter from a starting diameter substantially larger than the diameter of the molded lens, until the lens self-detaches from the mold.
