Abstract
An accommodating intraocular lens is disclosed that provides vision accommodation in response to contraction of an eye's ciliary muscle. The intraocular lens includes a deformable elastic dynamic lens having a non-accommodating surface curvature and a lens-shaping member having flexible portions in contact with peripheral edge regions of the dynamic lens for enabling compressive deformation thereof for changing the lens surface curvature to achieve accommodation. The intraocular lens also includes an elastically flexible coil member mounted around the lens-shaping member flexible portions. A first lens-supporting member has a proximal end region that engages the flexible coil member and a second lens-supporting member has a proximal end region connected to the lens-shaping member.
