Abstract
This invention relates to a method for correcting visual refractive errors of the human eye. In this method, a contact lens is fitted to the patient's eye, the lens being oxygen permeable, wettable, and having an oxygen permeable crosslinking agent.
Claims3
A method of correcting refractive errors of the eye by the steps of copolymerizing 1,1,1tris(trimethylsiloxy)methacryloxypropylsilane and methylmethacrylate monomer with the oxygen permeable crosslinker Bis(methacryloxypropyl)tetramethyldisiloxane to form an oxygen permeable transparent solid copolymer, cutting and polishing the surfaces of the transparent permeable crosslinked copolymer to form a correcting lens to be worn on the cornea of the eye.
A method of correcting refractive errors of the eye by the steps of copolymerizing 1,1,1tris(trimethylsiloxy)methacryloxypropylsilane and methylmethacrylate monomer with the oxygen permeable crosslinker Bis(3-glycidoxypropyl)tetramethyldisiloxane to form an oxygen permeable transparent solid copolymer, cutting and polishing the surfaces of the transparent permeable crosslinked copolymer to form a correcting lens to be worn on the cornea of the eye.
A method of correcting refractive errors of the eye by the steps of copolymerizing methylmethacrylate monomer with the oxygen permeable crosslinker Bis(3-glycidoxypropyl) tetramethyldisiloxane to form an oxygen permeable transparent solid copolymer, shaping the transparent permeable crosslinked copolymer to form a correcting lens to be worn on the cornea of the eye.
