Accommodating intraocular lens
First Claim
1. An accommodating intraocular lens device for treatment of an eye, the device comprising:
- an optical, lens body having a sealed chamber containing a fixed volume of optical fluid, the lens body comprising;
an anterior lens element comprising a perimeter region and a central surface surrounded by the perimeter region, the central surface configured to outwardly bow;
an annular support coupled to the perimeter region of the anterior lens element, the annular support having a shape deformation membrane extending along an arc of the annular support, the shape deformation membrane configured to undergo displacement relative to the perimeter region of the anterior lens element;
a static, posterior lens element positioned opposite the anterior lens element;
an immovable, internal support encircling the central surface of the anterior lens element, wherein the immovable, internal support has an anterior-facing surface coupled to the perimeter region of the anterior lens element and has an anterior-to-posterior thickness; and
the fixed volume of optical fluid,wherein an inner surface of the anterior lens element, an inner surface of the shape deformation membrane and an inner surface of the static, posterior lens element collectively form the sealed chamber of the lens body containing the fixed volume of optical fluid;
a force translation arm having a first end configured to contact an outer surface of the shape deformation membrane of the lens body and a free end available and configured to engage a ciliary structure of the eye outside the capsular bag when the lens device is implanted in the eye such that an optical axis of the lens body is substantially aligned with a visual axis of the eye,wherein the force translation arm is movable relative to the lens body and the immovable, internal support to cause inward movement of the shape deformation membrane; and
a stabilization haptic coupled to the lens body.

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.
