Abstract
A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and a pair of integrally formed, plate-style haptics. The haptics project posteriorly from the optic. A plurality of openings are formed at the intersection of the optic and the haptics, the holes extending all the way through the lens. The distal tips of the haptics are split or forked so as to project anteriorly and posteriorly. The anterior arm is designed to fit against the posterior iris, and the posterior arm is design to be supported in the anterior ciliary sulcus. Such a construction provides for a stable lens once implanted in the eye, helps to avoid pupillary blockage and allows for improved aqueous flow around the natural lens.
