摘要: A method for making a silicone hydrogel contact lens is provided. In one embodiment, a prepolymer mixture is polymerized in a lens mold in an atmosphere having less than about ppm oxygen to form a silicone hydrogel contact lens suitable for extended wear as characterized by producing less than 10% corneal swelling after a period of continuous wear of 7 days including normal sleep periods. In one embodiment, the prepolymer mixture comprises at least one oxyperm material containing hydrophilic groups, wherein the at least one oxyperm material is a siloxane-containing macromer or monomer, at least one ionperm material, and a cross-linking agent. In certain embodiments, the polymerization of the prepolymer mixture may be carried out in an atmosphere having less than about 1000 ppm oxygen.

摘要: An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. In one embodiment, an opthalmic lens is a copolymerization product of at least one oxyperm, at least one ionoperm, and a crosslinker. In one embodiment, a lens has a tensile modulus of less than about 3.0 MPa, yet in another embodiment, the tensile modulus is between about 0.5 to about 1.5 MPa.
