An accommodating intraocular lens (32) to be implanted within the natural capsular bag (20) of a human eye (10) from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant (22). During postoperative healing, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis (42) about haptics (36) on the implanted lens while the ciliary muscle (28) is maintained in its relaxed state, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant (22) to a distant vision position against the elastic posterior capsule (24) of the bag in which the posterior capsule is stretched rearwardly.

Accommodating intraocular lens

Intraocular lenses (50) for implanting within the natural capsular bag of the human eye having features on the outer ends (54, 114, 136, 128) or portions of the lenses to fixate the lens within the natural capsular bag following implantation.

Intraocular lenses with fixated haptics

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.

Accommodating intraocular lens having T-shaped haptics

A refractive intraocular lens (104) and method of locating the lens within the eye and attaching the lens to the iris. The refractive intraocular lens (104) may be attached via a staple (230), a fastener (312), anchor (412) or by the tip of the haptic (118).

Refractive intraocular implant lens and method

The invention is a phakic intraocular lens (IOL) for the correction of visual disorders such as myopia, hyperopia, astigmatism and presbyopia. The lens is made from a biocompatible, elastomeric material such as silicone. The lens further includes one or more annular surfaces that protrude from the anterior surface of the lens or surround the lens such that when placed in the eye, it makes contact with the iris. As the iris dilates and constricts, the contact with the iris places a centering force on the implanted lens. The lens is not in contact with the natural lens of the eye and floats in the posterior chamber without insult or abrasion to surrounding tissue.

Self-centering phakic intraocular lens

A posterior-chamber intraocular prosthetic lens includes an optical lens (1) and two diametrically opposite supporting elements (2), each of the supporting elements (2) being shaped as a curvilinear body one of its lateral surfaces being convex and facing with its convex portion (3) in a direction opposite to the lens principal plane, while the other lateral surface of the body is cancave and faces with its concave portion (4) toward the lens (1) principal plane; the ends of the supporting elements (2) are rounded off and face each other, while the supporting elements (2) are spatially turned away from each other with respect to the principal plane of the optical lens.

Posterior-chamber intraocular prosthetic lens

An artificial rear-chamber crystalline lens comprises a lens (1) and two diametrically-opposed supporting elements (2) each shaped as a curved body, one side surface of which is convex and faces by its convexity (3) in a direction opposite to the main plane of the lens (1), and the other side surface of which is concave and faces by its concavity (4) the main plane of the lens (1). The ends of the supporting elements (2) are rounded and face each other, whereas the supporting elements (2) are rotated in space in relation to the main plane in mutually opposite directions.
