Abstract:
An accommodating intraocular lens for implantation in an eye having a lens capsule and an optical axis, said lens comprising:an optical axis configured to coincide substantially with the optical axis of the eye upon implantation of said lens; an anterior portion comprised of a viewing element, said viewing element comprised of an optic having refractive power; a posterior portion comprised of a viewing element, said anterior portion and posterior portion meeting at first and second apices of said intraocular lens, said apices living substantially on a transverse axis of said lens, said viewing elements mounted to move relative to each other along the optical axis of the eye between an accommodated state and an unaccommodated state in response to force generated by the ciliary muscle of the eye; a distending portion comprised of a first distending member attached to one of the anterior portion and the posterior portion, said first distending member spaced outwardly from said optical axis of said lens, an outermost portion of said first distending member oriented to contact and distend a portion of the lens capsule such that coupling of forces between the lens capsule and the intraocular lens is modified by said distending portion; wherein said outermost portion of said first distending member is closer to said transverse axis, as measured along a direction generally parallel to the optical axis of the lens while said lens is viewed from the side, when said viewing elements are in said unaccommodated state, than when said viewing elements are in said accommodated state.
