A single-optic accommodative lens
system comprising two intraocular elements. The two intraocular elements are designed to be located within the
capsular bag to extend
depth of focus and / or restore
accommodation following 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. Capsular force can be applied to the IOL from anterior, posterior and / or intermediate sections of the
capsule equator, resulting in movement of the IOL and commensurate
accommodation.
