Abstract

An accommodating intraocular lens implant includes an anterior floating lens unit, a posterior lens unit, an anterior lens link, a posterior lens link, and an anterior rim link, which comprises an anterior rim jointed element. An anterior rim complex is disposed such that the anterior floating lens unit is movable toward and away from the anterior rim complex, in an anterior-posterior direction. A lever is connected (a) at a first longitudinal site along the lever, to the anterior floating lens unit by the anterior lens link, (b) at a second longitudinal site along the lever, to the anterior rim complex by the anterior rim link, and (c) at a third longitudinal site along the lever, to the posterior lens unit by the posterior lens link. The second site is longitudinally between the first and the third sites along the lever, such that the second site serves as a fulcrum for the lever.
