Abstract:
1. An intraocular lens comprising: an optic portion including a lens element configured to be deflected between an accommodated configuration and an unaccommodated configuration, wherein the optic portion includes an optical axis extending in an anterior to posterior direction; and a haptic having an interior volume filled with a fluid, wherein the haptic is in fluid communication with the optic portion, wherein the haptic is configured such that movement of the capsular sac changes the interior volume of the haptic and wherein a first portion of the haptic is adapted to engage the capsular sac, wherein the haptic, at a location in the first portion, has a cross-sectional configuration in a non-stressed configuration in a plane extending in the anterior to posterior direction in which a maximum linear anterior-to-posterior dimension between any two points on an outer surface of the haptic is greater than a maximum linear radial dimension between any two points on an outer surface of the haptic, and wherein the lens element is configured to change curvature in response to changes in the interior volume of the haptic such that it transitions between the accommodated state and the unaccommodated state.
