US 2004/0111153 A1 · Capsular intraocular lens implant having a refractive liquid therein

Abstract

An intraocular lens having a light-transmitting optic (32, 94a, 94b, 142, 148, 216) comprised of a synthetic light-refractive material (40, 102) operably coupled with a flexible optic positioning member (34, 62, 74, 84, 100, 150, 210) to refract light onto the retina in order to correct refractive errors in the eye (10). The refractive material has an index of refraction of from about 1.36 to 1.5 or higher. The optic positioning member (34, 62, 74, 84, 100, 150, 210) is constructed of a flexible synthetic resin material such as polymethylmethacrylate and permits focusing upon objects located near to and far from the viewer. The optic (32, 94a, 94b, 142, 148, 216) of the present invention possess greater refractive capability than optics conventionally used in IOL construction, and permits retinal receipt of the image being viewed in order to correct refractive errors.

Dependent claims

An implantable intraocular lens adapted for positioning within the capsule of a human eye as a replacement for the natural lens, said intraocular lens comprising:

an optic comprising a resilient, shape-retaining synthetic material;
an optic positioning member operably coupled with said optic and responsive to ciliary body movement in order to change the shape of said optic between a first optic shape and a second optic shape, where said second optic shape has a thickness that is greater than said first optic shape,
said positioning member comprising a main body including anterior and posterior segments, said optic being connected to said positioning member in a location central to said anterior and posterior segments.
