Abstract
A single-optic accommodative lens system includes two intraocular elements designed to be located within the capsular bag to extend depth of focus and/or restore accommodation following cataract extraction of a natural lens. A first intraocular element comprises a circumferential capsular ring having interlock features to couple to and control the dynamic vault response of a second intraocular element. This second intraocular element comprises an intraocular lens (IOL) having an optic and a plurality of haptics and is designed to move axially in response to changes in the geometry of the eye capsule and thus provide a range of accommodative power. The IOL further comprises interlock features complementary to the interlock features of the first intraocular element for coupling the IOL to the capsular ring in a manner that provides for controlled movement of the IOL in response to capsular forces.
