Patent ID: 7635388

Claim:
In a system comprising an adjustable intrascleral prosthesis comprising at least two layers and useful for altering the size or shape of the sclera of an eye to improve its accommodative capability, the improvement comprising: an arcuate first layer comprising a synthetic resin, said first layer being a shrinking layer; and an arcuate second layer comprising a synthetic resin substantially coextensive with said first layer and attached to said first layer, said first layer having an ASTM melt index different from the ASTM melt index of said second layer, and said second layer being a bending layer; said prosthesis being curved such that its curvature substantially corresponds to that of a human sclera and having a convex surface and a concave surface such that said convex surface is adapted to face in the anterior direction and said concave surface is adapted to face in the posterior direction when said device is implanted in the eye; and a source of energy, selected from the group consisting of laser energy, UV sources, IR sources, radio frequency emitters, heat, and low voltage DC and low voltage high frequency sources; wherein said prosthesis is operable to assume a first radius of curvature at a selected temperature, and a second radius of curvature after application of said energy to said prosthesis, said second radius of curvature being different than said first radius of curvature.
