US 2004/0073304 A1 · Adjustable intraocular lens

Abstract

An adjustable lens system. In a first embodiment, the lens system of the present invention is a two optic system. The optics are connected by an expandable material that allows the distance between the optics to increased in-situ. In a second embodiment of the present invention is a single optic system having a section made from an expandable material at or near the junction between the optic and the centering haptics. Expansion of these section causes the haptics to move radially away from the optic. Such movement may allow for recentering of the lens or, if the haptics are slightly vaulted, radial movement of the haptics away from the optic will cause axial movement of the lens system along the visual axis.
