Abstract:
An accommodating intraocular lens for implantation into a generally circular inner surface of an eye, comprising:(a) a lens body having an optic and having at least two optic hinge portions, (b) at least two haptics, each haptic having a haptic hinge portion pivotally connected to said optic hinge portions, said haptics spaced apart from each other generally radially away from the optic, adapted to engage the generally circular inner surface of the eye for holding the lens in the eye; (c) each of the haptics including an outer portion with a surface adapted to engage the generally circular inner surface of the eye, at least part of said outer surface extending beyond the diameter of the generally circular inner surface of the eye, when said outer portion is in its unstressed state, said outer portion being flexible and not conforming to the generally circular inner surface of the eye until subjected to compressive forces, so that the outer surface will conform generally to the shape of the inner surface of the eye when subjected to said compression forces upon implantation; and (d) the haptics being pivotally moveable through a certain angle anteriorly and posteriorly relative to the optic in response to forces imparted to the lens through contraction and expansion of the generally circular inner surface of the eye.
