Abstract:
PROBLEM TO BE SOLVED: To provide hydrophilic coating compositions for surgical implants, particularly ophthalmic implants comprising silicone, hydrophobic acrylic or hydrogel materials.SOLUTION: There are provided covalently-bound, hydrophilic copolymer coatings for implants. The copolymer coatings comprise 2-phenylethyl (meth)acrylate, a hydrophilic monomer that is selected from the group consisting of hydroxyalkyl (meth)acrylates; polyethylene glycol(200-500) mono(meth)acrylates; polyethylene glycol(200-500) monomethylether mono(meth)acrylates; and acrylamides, and a cross-linking agent.
Abstract:
Disclosed are soft, high refractive index, acrylic device materials having improved strength. The materials contain cross-linked acrylate or methacrylate microspheres.
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.
