Abstract
Hydrophilic coatings for implantable ophthalmic lenses are disclosed. The coatings, which are applied to the edge surface of the ophthalmic lens, comprise a hydrophobic (meth)acrylic polymer and a hydrophilic polymer. When hydrated, the coatings reduce or eliminate edge glare.
Claims1
A hydrophilic coating material for a surgical implant wherein the coating material has a Tg less than 37° C. when hydrated and comprises an ophthalmically acceptable hydrophobic (meth)acrylic polymer and an ophthalmically acceptable hydrophilic polymer, and wherein the hydrophobic (meth)acrylic polymer comprises a monomer selected from the group consisting of 2-phenylethyl acrylate and 2-phenylethyl methacrylate.
