Abstract

Prosthetic implants designed to be implanted in the cornea for modifying the cornea curvature and altering the corneal refractive power for correcting myopia, and myopia with astigmatism, such as implants formed of a micro-porous hydrogel material. The lenses (166, 168) include rib sections (166a, 168a), respectively, which extend across the center of each lense and define voids between the ribs and the outer periphery of the lense.
