Beschreibung
Zusammenfassung:	An improved intraocular lens, methods of fabricating the same, and methods of implantation of the intraocular lens in a human eye. The intraocular lens implant is a hydrogel and has an index of refraction approximating the refractive index of the natural crystalline lens of the human eye. Fabrication of the intraocular lens is effected in an open concave mold which has a sharp, well-defined peripheral mold edge. The intraocular lens is implanted in the posterior chamber after the cataract operation.
