Abstract:
A method of forming a one-piece intraocular lens, comprising:(a) polymerizing a mixture comprising a hydrophilic monomer, an alkoxyalkyl methacrylate monomer, and a crosslinking monomer to form a copolymer comprising an incorporated hydrophilic monomer, an incorporated alkoxyalkyl methacrylate monomer, and at least 0.25 percent up to about 10 percent by weight of an incorporated crosslinking monomer based on the total weight of the dry copolymer; (b) forming the copolymer into the one-piece intraocular lens, wherein the one-piece intraocular lens comprises a haptic portion and an optic portion formed from the copolymer and the hydrated copolymer has an equilibrium water content of from 38 percent to about 10 percent by weight based on the total weight of the hydrated copolymer.
