Abstract

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.

Dependent claims

An accommodating intraocular lens, comprising:

an optic portion including an anterior lens element and a posterior surface,
a peripheral portion extending radially outward from the optic portion;
and
wherein the optic portion is adapted to deform to change the power of the lens after being implanted in an eye;
wherein the peripheral portion has a proximal portion secured to the optic portion and then extends away from the proximal portion and follows a radially outer periphery of the optic portion;
wherein the peripheral portion includes a radially inner backstop region that has a height dimension, measured in an anterior-to-posterior direction, that is less than a greatest height dimension of the peripheral portion, the backstop region having a radially inner surface that protrudes radially inward relative to a surface of a second peripheral portion region that is directly adjacent to and anterior to the radially inner backstop region, the radially inner backstop region extending to the radially outer periphery of the optic portion at a location that is spaced from where the proximal portion of the peripheral portion is secured to the optic portion, and wherein the backstop provides radially inner support for the peripheral portion.
