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 haptics. The haptics project posteriorly from the optic. A plurality of holes or slots are formed along the edge of the optic and along the length of the haptics. A soft, highly biocompatible material may be placed into the holes or slots by a friction fit or a primary/secondary molding process. Such a construction helps to avoid pupillary blockage, allows for improved aqueous flow around the natural lens and provides a spacer to hold the lens away from the anterior capsular and the iris.
