Abstract:
1. An accommodating intraocular lens comprising an anterior viewing element, a posterior viewing element, first and second distending members joined to the posterior viewing element and not joined to the anterior viewing element, and a biasing structure, the anterior and posterior viewing elements having refractive power, the biasing structure defining a side opening in the accommodating intraocular lens, the opening extending by a distance greater than a diameter of at least one of the anterior and posterior viewing elements, the biasing structure being configured to move the viewing elements relative to each other along an optical axis between an accommodated state and an unaccommodated state in response to action of a ciliary muscle, the viewing elements being spaced farther apart in the accommodated state than in the unaccommodated state, the biasing structure being formed of silicone, at least one of the optics being formed of acrylic, the diameter extending transverse to and intersecting the optical axis of the lens, said distending members being substantially separate from the biasing structure, a first end of each of said distending members being fixed relative to the posterior viewing element, a second end of each of said distending members extending anteriorly of the posterior viewing element and radially outwardly away from the optical axis beyond a perimeter of the posterior viewing element.
