  • Patent number: 8025823
    Abstract: There is disclosed an accommodating intraocular lens for implantation in an eye having an optical axis. The lens comprises an anterior portion which in turn comprises an anterior viewing element and an anterior biasing element. The lens further comprises a posterior portion which in turn comprises a posterior viewing element in spaced relationship to the anterior viewing element and a posterior biasing element. The anterior portion and posterior portion meet at first and second apices of the intraocular lens. The anterior portion and the posterior portion and/or the apices are responsive to force thereon to cause the separation between the viewing elements to change. Additional embodiments and methods are also disclosed.

  • Patent number: 6818158
    Abstract: There is disclosed a method of making an intraocular lens having first and second viewing elements. The viewing elements are interconnected by a plurality of translation members extending from a periphery of the first viewing element. At least one of the translation members comprises a plurality of arms, and at least one of the viewing elements includes an optic having refractive power. The method comprises providing a first outer mold and a second outer mold, and an inner mold therebetween. The first outer mold and the inner mold define a first mold space, and the second outer mold and the inner mold define a second mold space. The method further comprises molding the viewing elements, the plurality of arms and the optic as a single piece by filling the first and second mold spaces with a material, such that the first viewing element and the plurality of arms are formed in the first mold space and the second viewing element is formed in the second mold space.
