摘要： The invention provides an improved process in which minimal force is required to separate mold halves so as to minimize lens damages resulted from the forced separation of mold halves. The process of the invention comprises: providing a mold including a first mold half having a first molding surface and a second mold half having a second molding surface, wherein the first and second mold halves are configured to receive each other such that a mold cavity is formed between the first and second molding surfaces, wherein one of the first and second mold halves has a collar that encircles the other mold half to provide a seal between the two mold halves when the mold is closed; dispensing a specific amount of a polymerizable lens-forming material into one of the mold halves; mating the mold halves to close the mold; polymerizing said polymerizable material located between the two mold halves, thereby forming a molded contact lens; applying a small force to the collar to distort the collar, thereby breaking the seal between the two mold halves; and opening the mold.

摘要： The invention provides a method for washing, with a water-based system, reusable molds for making silicone hydrogel contact lenses. The water-based washing system comprises an ethoxylated silicone polyether surfactant. The water-based system of the invention can effectively wash away silicone-containing components and other components of a lens formulation left behind on the molding surfaces of a reusable mold, after removing a silicone hydrogel contact lens cast molded in the reusable mold.

摘要： A contact lens and a method for manufacturing thereof are provided. The contact lens has a silicone contact lens base material and an amorphous carbon film formed in the silicone contact lens base material. The amorphous carbon film of the contact lens is formed by subjecting the silicone contact lens base material to a plasma polymerization under an atmosphere of a mixed gas comprising a hydrocarbon gas and an oxygen-containing gas. The contact lens has excellent oxygen permeability and a high refractive index.
