ABSTRACT:
An artificial intraocular lens for surgical implantation to replace a damaged natural lens in an otherwise functional eye of a patient is disclosed as having a dome-shaped central disc portion, haptic loops formed on said central portion, for centering said central portion after implantation, wherein the central portion is composed of a dry, solid hydrophilic material capable of hydration by the natural fluid present in the eye to expand after implantation to provide an optically correct lens, wherein the central portion has a cross-sectional dimension substantially less than that of the natural lens and wherein said haptic loops are configured such that said central portion is centered upon implantation and remains centered during expansion thereof, thus improving the vision of the patient.
