摘要：An artificial intraocular lens for implantation in the posterior chamber of an eyeafter intracapsular or extracapsular lens extraction comprises a transparent optical zoneportion shaped similar to the natural lens and a plurality of prongs protruding forwardlyfrom the periphery thereof, wherein after implantation of the artificial intraocular lensthe prongs extend through the iris to anchor the lens in the posterior chamber of theeye. The prongs protrude forwardly from the lens and are curved so that the outer endsof the prongs extend generally along the periphery of the lens, and the prongs arepreferably arranged in pairs with the prongs in each pair extending in opposite directionsalong the periphery of the lens. A peripheral flange may be provided surrounding theoptical zone portion for attaching the prongs to the lens, and a plurality of openings maybe provided in the flange adjacent to the optical zone portion to permit passage ofaqueous fluid from the ciliary body to the anterior chamber.
