An intraocular lens (30) having focusing capabilities permitting focusing movement of the lens (30) in response to normal ciliary body (24) movement incident to changes in the distance between the eye and an object under observation is provided. The lens (30) is designed for surgical implantation within the capsule (20) of an eye (10) and includes an optic (32) and an optic positioning element (33) which cooperate to form the lens (30). Accommodation is achieved by relying upon the thickening and thinning of the optic (32) as a result of the normal retracting and contracting of the ciliary body (24) in response to the distance of an object from the viewer.

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.

An intraocular implant including a lens and a shell component. The shell component includes a shell peripheral wall encompassing a shell inner volume for protectively enclosing the lens and allowing the latter to move therein between lens accommodating positions. The lens is pivotable within the shell inner volume between a lens first position wherein the lens is in a substantially proximal relationship relative to a shell wall first segment and a lens second position wherein the lens is in a substantially proximal relationship relative to a shell wall second segment. In one embodiment of the invention, the lens peripheral edge defines a lens edge pivot portion and the shell segment joining edge defines a corresponding shell edge pivot portion, the lens and shell edge pivot portion being complementarily configured and sized so that when the lens abuttingly rests against the peripheral wall inner surface, the lens and shell edge pivot portions interact with each other for allowing the lens to pivot between the lens first and second positions.In another embodiment of the invention, the lens is pivotally suspended within the shell component for pivotal movement between the lens first and second position. In both embodiments, the lens may also pivot to a lens intermediate position in a spaced relationship relative to both the the shell wall first and second segments.

A method of manufacturing an intraocular lens inside a capsular bag after the natural lens has been removed employs a sealing device comprising a plug part adapted to seal a rhexis in a capsular bag, thus preventing displacement through the rhexis of a lens-forming liquid material injected through the rhexis and adapted to replace the natural lens and form an intraocular lens implant. The plug part has a slightly larger area than the capsulorhexis and is made of a deformable polymer. The sealing device further comprises an adjusting means connected to the plug part and adapted to position the plug part to a desired location.

An intraocular implant for implantation into the interior of an eye is disclosed.

Intraocular lens implant that includes a lens optic and lens haptics configured to maintain a preoperative position of the posterior lens capsule after cataract removal and insertion of a lens implant. The lens haptics have proximal and distal portions, with the distal portions lying in a common plane and the lens optic extending in a lens optic plane. The distance between the planes may be at least substantially the same dimension as or larger than a shift distance that the posterior lens capsule would otherwise traverse between its normal anatomical location and its shifted anatomical location where it not constrained. The shifted anatomical location arises naturally after both removal of cataract lens material and removal of a portion of an anterior capsule.

An intraocular lens implant includes a lens having an anterior portion, a posterior portion, and a circumferential edge located therebetween. An annular notch is formed in the anterior portion and oriented in an anteriorly-directed orientation.

The present invention provides a hydrogel-based intraocular lens (IOL) implant that can covalently attach to a lens capsule on implantation into an eye. The inventive IOL has a high refractive index, high elasticity, and is of a similar size to a naturally occurring lens. In addition, the IOL can be implanted in a smaller, dehydrated state, allowing the IOL to be placed in the lens capsule with a small incision (up to about 1 / 10 the volume of the IOL). Exposure to fluid can then initiate rapid swelling of the dried polymer to the shape and dimensions of a natural lens, with full occupation of the lens capsule. Upon equilibrium swelling, the IOL can then make contact with the inner aspect of the lens capsule and covalently bind to it. By this attachment process, the IOL may accommodate in a manner identical to that of the natural lens.
