Abstract
An accommodating intraocular lens device for treatment of an eye having a lens body; internal support; stabilization system; and force translation arm. The lens body includes an accommodating membrane, an annular element, a static element, and a fixed volume of optical fluid filling a sealed chamber of the lens body. The annular element coupled to the perimeter of the accommodating membrane has a shape deformation membrane configured to undergo displacement relative to the perimeter region. The sealed chamber is formed by inner surfaces of the accommodating membrane, shape deformation membrane, and static element. The force translation arm has a first end operatively coupled to the shape deformation membrane and a free end available and configured to engage a ciliary structure of the eye. The force translation arm is moveable relative to the lens body to cause inward movement of the shape deformation membrane. Related methods, devices, and systems are provided.
