Abstract

Disclosed is an accommodating intraocular lens device for treatment of an eye including a stabilization haptic (120) configured to be positioned within a region of an eye and a lens body having a sealed chamber containing a fixed volume of optical fluid. The lens body includes a shape changing membrane (145) configured to outwardly bow in a region surrounding the optical axis of the eye; a shape deformation membrane configured to undergo displacement relative to the first shape changing membrane; and a static element (150). An inner surface of the shape changing membrane, an inner surface of the shape deformation membrane and an inner surface of the static element collectively form the sealed chamber. The lens device also includes a force translation arm (115) having a first end configured to contact an outer surface of the shape deformation membrane of the lens body and a second end configured to engage a ciliary structure of the eye. The force translation arm is configured to move relative to the lens body upon movement of the ciliary structure.
