ABSTRACT:
An intraocular lens for implant in the eye, particularly in the anterior chamber, includes a lens body and a plurality of positioning members having proximal portions extending from the lens body supporting flexible, resilient curved filaments with the proximal portions having a width greater than the filaments to provide stable positioning in the eye and prevent pupillary capture of the lens body. In another embodiment, an intraocular lens has at least three flexible, resilient, fixation filaments extending from the periphery of a lens body and having continuous curving configurations, the fixation filaments being positioned to prevent pupillary capture of the lens body.
