IOL of the type which include a lens, haptics and a curving ring wherein there are soft haptics and rigid haptics, both being associated through a lever and wherein a softer outer ring houses in its inner geometry an inner curving ring, the latter being rigid and incomplete, with curving flaps in whose geometry the assembly consisting of lens and haptics is housed.

A suspension system for suspending an intra-ocular lens in the lens capsule of an eye has one or more collapsible cavities formed in the suspension system, each having at least one opening communicating the interior of the cavity with fluid from the interior of the eye, wherein the walls of the cavity exhibit sufficient structural elasticity that they return to their habitual shapes after being compressed by external force.

Eye surgery methods which isolate segments of the eye capsule to which the relevant zonules are attached via a specially contoured capsulorhexis, and shrink-wrap these segments to the haptics of an AIOL to disaccommodatively actuate the latter, accommodative actuation of the AIOL being effected by an accommodative bias built into the AIOL, a tensioning ring, or both.

A two-piece intraocular lens (IOL) with an anterior shape-changing optic is provided. The shape-changing interchangeable optic includes an elastic anterior face located anterior to the equator and comprising anterior arms releasably connected to actuating haptics of a base.

Accommodating intraocular lenses containing a flowable media and their methods of accommodation.

Embodiments of the invention relate to an intraocular lens system having a plurality of haptics for use with an optic. In general, the haptics are adapted to move independently in response to forces associated with a ciliary muscle and/or zonules of an eye when implanted. The optic may be releasably secured to the system using, for example, a plurality of optic securing arms. Alternatively, the optic may be fused to the haptics, which may project radially outward from the optic. A restraining arm may be included to limit movement of the haptics during accommodation and/or disaccommodation. Clamping members may be included for securing the system to a capsular bag of the eye. Methods of implanting the intraocular lens system into the eye are also described.

An accommodating intraocular lens (IOL) is provided. The IOL includes an optic having an anterior face and a posterior face. One or more centration lips are disposed directly on the posterior and/or anterior face of the optic or directly on the posterior and/or anterior face of a carrier that holds the optic. Anterior centration lips are configured to center the optic in a lens capsulotomy opening. Posterior centration lips are configured to fixate the optic in a lens capsule and also center the optic in a lens capsulotomy opening.

Eye surgery methods which isolate segments of the eye capsule to which the relevant zonules are attached via a specially contoured capsulorhexis, and shrink-wrap these segments to the haptics of an AIOL to disaccommodatively actuate the latter, accommodative actuation of the AIOL being effected by an accommodative bias built into the AIOL, a tensioning ring, or both.

An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.

An intraocular lens (IOL) device comprising a first lens, a second lens and a circumferential haptic. The first lens comprises a pair of opposing and deformable surfaces and a cavity defined therebetween. The first lens has a first lens diameter. The second lens has a second lens diameter. The circumferential haptic has an outer peripheral edge and couples the first lens and the second lens. A main IOL cavity is defined by the circumferential haptic, the first lens and the second lens. The IOL device is resiliently biased to an unaccommodated state, characterized by the IOL device having a first diameter d.sub.1 in the absence of radial compressive forces exerted on the outer peripheral edge. The IOL device actuates to an accommodated state being characterized by a second diameter d.sub.2 in response to radial compressive forces exerted on the outer peripheral edge, wherein d.sub.1>d.sub.2.
