Claim Text:
1. An intraocular lens comprising at least one copolymer comprising: (a) a first monomeric subunit comprising a polymerized 2-hydroxy-3-phenoxypropyl acrylate, (b) a second monomeric subunit comprising a polymerized 2-ethoxyethyl methacrylate, (c) a third monomeric subunit comprising a polymerized-polyethylene glycol monomethyl ether methacrylate with a polyethylene glycol molecular weight of 200 to 400, and (d) a trimethacrylate crosslinker subunit, wherein the polymerized 2-hydroxy-3-phenoxypropyl acrylate is 50% to 70%, by weight of the copolymer, and the polymerized 2-ethoxyethyl methacrylate is 20% to 35%, by weight of the copolymer, and the polymerized polyethylene glycol monomethyl ether methacrylate with a polyethylene glycol molecular weight of 200 to 400 is 5% to 15%, by weight of the copolymer, and the trimethacrylate crosslinker is 0.5 to 3%, by weight of the copolymer, wherein the intraocular lens when hydrated has an SI value of less than 800.
