摘要：
An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. The 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 the haptic portion of 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. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.
