Abstract
An intraocular accommodating lens comprising a resilient polymer monolith with a peripheral component that has a Young's modulus and an equilibrium memory shape that imparts to the capsular sac's periphery the natural shape of the capsule in an accommodated state. The intraocular lens includes a central deformable optic that provides accommodated and disaccommodated shapes. The peripheral component is deformable to a disequilibrium, stressed shape in responsive to equatorial tensioning—and is capable of applying restorative forces to move the lens toward the accommodated shape from a disequilibrium disaccommodated shape. In one embodiment, the central optic portion includes a displaceable media than can be displaced by very low forces of zonular excursion, wherein the displaceable media can comprise a very low modulus polymer or an index-matched fluid.
