Patent ID: 7753953

Claim:
An accommodating intraocular lens system for implantation in a capsular bag of an eye, the system comprising: an optic component comprising a first light-transmitting lens element and a second light-transmitting lens element defining a fluid-filled deformation chamber located between the first and second lens elements, at least one of the first and second lens elements comprising an elastic membrane adapted to deform in response to a change in pressure, the elastic membrane including a first portion having a first deformation response and including a second portion having a second deformation response, wherein the first deformation response differs from the second deformation response, and comprising a peripheral rim sealing a periphery of the first lens element to a periphery of the second lens element; a refractive fluid filling the deformation chamber; and at least one haptic member coupled to the optic component and configured for changing a hydrostatic pressure in the deformation chamber in response to muscle movement in the eye in order to deform the elastic membrane of at least one of the first and second lens elements, thereby changing the shape and the refractive characteristics of the optic component, wherein the peripheral rim including an attachment component for coupling the at least one haptic member to the optic component and a slot extending into the deformation chamber for allowing a portion of the at least one haptic member to move into and out of the deformation chamber in response to a contraction and a relaxation of the eye during accommodation, wherein the at least one haptic member comprises an accommodation arm adapted to engage an inner surface of the capsular bag and a displacement arm, the accommodation arm rigidly connected to the displacement arm at an elbow and forming an acute angle with the displacement arm, and wherein the attachment component comprises a hinge portion that pivotally couples the at least one haptic member at the elbow and positions the displacement arm at the slot such that when the capsular bag contracts and relaxes during accommodation, the displacement arm rotates into and out of the deformation chamber via the slot, thereby changing the hydrostatic pressure therein.
