Patent ID: 7226478

Claim:
An accommodating intraocular lens for implantation in an eye having an optical axis, said lens comprising: an anterior portion comprised of a viewing element, said anterior viewing element comprised of an optic having a refractive portion with a refractive power of less than 55 diopters; a posterior portion comprised of a viewing element; said lens having an optical axis which is adapted to be substantially coincident with the optical axis of the eye upon implantation of said lens; said posterior viewing element comprising an optic arranged substantially coaxially with said anterior optic on said optical axis of said lens, said posterior optic having a larger diameter than said refractive portion of said anterior optic, said posterior optic comprising a peripheral portion having positive refractive power and extending radially away from said optical axis of said lens beyond the periphery of said refractive portion of said anterior optic, so that at least a portion of the light rays incident upon the posterior optic can bypass said refractive portion of said anterior optic; wherein said anterior optic and said posterior optic are configured to move relative to each other along said optical axis of said lens between an accommodated state and an imaccommodated state in response to force on said intraocular lens by the ciliary muscle of the eye, said anterior optic and said posterior optic being separated when in the accommodated state; wherein said peripheral portion of said posterior optic has a refractive power of about 20 diopters.
