Abstract:
An 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, three or four looped haptic elements each of non-uniform cross-section, each of non-uniform thickness as measured between an anterior surface for facing the cornea of the eye and a posterior surface for facing the retina of the eye of said haptic element and each permanently connected to said outer peripheral edge by two or more attachment portions of greatest haptic element thickness measured from the anterior to the posterior surface and becoming increasingly thin moving outwardly in a direction away from the optic portion, and each haptic element having flexible central portions flexible in a plane perpendicular to said eye's optical axis, unitarily formed with said attachment portions opposite said outer peripheral edge and dimensioned be the same or thicker in a plane parallel to the eye's optical axis than in a plane perpendicular to the eye's optical axis such that a compressive force sufficient to effect a 1.0 mm in diameter compression of said lens results in less than approximately 1.0 mm of axial displacement of said optic portion along the eye's optical axis.
