<p>An accommodating intraocular lens (32) having T-shaped haptic (36) extending from diametrically opposite edges of an optic (34) for implantation within a capsular bag (20) within an eye (10) having a posterior capsule (24) and an anterior capsule remnant (22) forming an anterior capsule opening (26) surrounded by an anterior capsular rim (22). The lens (32) is placed in the bag (20) with the outer haptic T ends (36b) between the capsular rim (22) and the posterior capsule (24) to accurately center the lens (32) in the bag (20). Fibrosis occurs about the T ends (36b) to fixate them in the bag (20) and about haptic plate portions narrower than the optic diameter between the optic (34) and the T ends (36b) and to form haptic pockets (25) containing the haptic plate portions so that natural contraction and relaxation of the ciliary muscle effects vision accommodation movement of the optic (34). One embodiment has thickened, contoured haptic (202) which slide, upon ciliary muscle contraction, relative to the posterior capsule (24) to provide enhanced anterior movement of the optic (34) for accommodation.</p> |
