Patent ID: 7776086

Claim:
A corneal implant, comprising: a lens body formed of an optically clear, bio-compatible material, the lens body having an anterior surface and a posterior surface, and an outer diameter edge; the bio-compatible material having a refractive index ranging from 1.36-1.39; and the anterior surface being convex in shape and being formed with a continuous aspheric surface, wherein the lens body is adapted to be disposed posterior to a first portion of the cornea and anterior to a second portion of the cornea when implanted, wherein the continuous aspheric surface is defined by the formula: X 2 +Y 2 +(1+Q)Z 2 +2ZR=0, wherein the Z axis is the optical axis of the implant, wherein the aspheric surface is a circularly symmetric surface about the Z axis with the apex of the surface at the coordinates X=0, Y=0, Z=0, wherein Z is the coordinate of the surface along the Z axis, wherein X and Y are the coordinates of the surface in the plane perpendicular to the Z axis, wherein R is the radius of curvature at the apex of the implant, and wherein Q is the surface asphericity of the aspheric surface and Q<0.
