US 6,554,860 B2 · Foldable iris fixated intraocular lenses

Abstract

A refractive anterior chamber iris fixated intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably two, three or four balanced haptic elements. Each haptic element is of a relatively narrow arch-like form. Each haptic element is also manufactured to have an inner portion and an outer portion for supporting the optic portion in a patient's eye. The inner portion of each haptic element is permanently connected to the outer peripheral edge of the optic portion. Each haptic element also includes a fixation clamp on the outer portion thereof and a central portion located between the outer portion and the inner portion.

Dependent claims

An anterior chamber iris fixated intraocular lens to be implanted within an eye generally perpendicular to the eye's optical axis comprising:

an outer peripheral edge defining an optic portion,
two or more arch-like haptic elements permanently connected to the outer peripheral edge, each continuously decreasing in thickness in a plane parallel to the eye's optical axis moving in a direction away from the outer peripheral edge to an outermost peak thereof, and
an iris fixation clamp formed in said outermost peak of each arch-like haptic element, capable of separating upon folding of said intraocular lens, to allow for folded implantation of said intraocular lens through a relatively small incision.

Dependencies are inferred from the claim text.
