Abstract
An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens, responsive to forces applied to a haptic portion to the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. Displacement of fluid to the actuator may either increase or reduce the degree of deflection imposed on the lens element by the actuator.
