Anterior-posterior-capsule-actuated hydraulic accommodative intraocular lenses and lens systems

摘要

An accommodative hydraulic intraocular lens system (AHIOL) has a cylindrical actuator contained within which is a hydraulic lens assembly. The hydraulic lens assembly has a transparent elastically reconfigurable membrane coupled to a fixed focus lens by a bellows and a refractive hydraulic fluid contained in the space defined by the membrane, the bellows and the lens, and is maintained at the upper range of its diopter power by the elastic properties of the bellows, springs, or both.
