Patent ID: 8038711

Claim:
An intraocular lens, comprising: (a) a lens body having a convex anterior body member, a convex posterior body member, a vision axis, and an outer perimeter, said anterior body member having an inner surface, and an outer surface which corresponds to a first outer surface of said lens body, both of which extend along first and second convex arcuate paths when viewed from outside said lens body, from the outer perimeter to a first apex proximate the vision axis, said posterior body member having an inner surface, and an outer surface which corresponds to a second outer surface of said lens body, both of which extend along third and fourth convex arcuate paths when viewed from outside said lens body, from the outer perimeter to a second apex proximate the vision axis, the inner surface of said anterior body member meeting the inner surface of said posterior body member at the outer perimeter, the vision axis extending from the first apex of said anterior body member through the second apex at the posterior body member; (b) a cavity in said lens body between the inner surface of said anterior body member and the inner surface of said posterior body member, said cavity being filled with a mixture of first and second liquids which have at least first and second different refractive indices of at least about 1.33, the first and second refractive indices being sufficiently different from each other to provide a distinct bifocal functionality along the vision axis at all orientations of the lens when implanted, said liquid mixture having a viscosity of about 4000 millipoise to about 7,000,000 millipoise, the cavity extending generally outwardly away from the vision axis to the outer perimeter; and (c) first and second flanges, each having a distal edge, said first and second flanges extending away from the outer perimeter of said lens body in first and second different directions, said first and second flanges being oriented approximately perpendicular to the vision axis, said first and second flanges being adapted and configured such that, when a pushing force is applied to the distal edges of said first and second flanges, said first and second flanges transmit such pushing force to said lens body at the outer perimeter and push against said lens body and cause changes in the first and second arcuate paths in the anterior body member, including at the vision axis.
