Abstract
An accommodating IOL includes a flexible optic membrane, a flexible skirt extending from an outer periphery of the flexible optic membrane and defining an outer periphery of the accommodating IOL, and a capsular contact ring configured to be positioned anterior to the flexible optic membrane and having a diameter less than a diameter at the outer periphery of the accommodating IOL. The accommodating IOL further includes a plurality of strut assemblies connecting the capsular contact ring and flexible skirt. When the capsular bag transitions from an accommodative state to a disaccomadative state, the capsular bag exerts a force on the capsular contact ring, at least a portion of that force being transferred to the flexible skirt by the plurality of strut assemblies. The transferred force causes a flattening of the flexible optic membrane in a manner that reduces the optical power of the accommodating IOL.
