Abstract
An accommodating intraocular lens (IOL) can be implanted either alone or as part of a two-part lens assembly. The IOL comprises an optic, a flexible membrane and a peripheral edge coupling the optic and the flexible membrane. The peripheral edge comprises an external circumferential surface having a height and a force transmitting area defined along a portion of the height of the external circumferential surface. A closed volume spaces apart the optic and the flexible membrane. The optic is axially displaced and the flexible membrane changes in curvature about a central axis when a radial compressive force is applied to the force transmitting area. A volume defined by the closed volume remains fixed when the optic is axially displaced and the flexible membrane changes in curvature and/or when the radial compressive force is applied to the force transmitting area.
