Abstract: An intraocular implant for placement in the eye, e.g. as part of a cataract operation or crystalline lens extraction refractive operation, has at a peripheral portion of the implant a groove which engages with the lip of a single capsulotomy only formed in the lens capsule of the eye. The implant will normally be a lens, but may instead be a bung or plug for occluding an opening made in the capsule. The groove may be a continuous groove around the periphery of the implant, or there may be a series of individual spaced-apart grooves formed as projections protruding from the periphery. Instead of a single groove, a pair of axially spaced-apart grooves may be provided, which engage with respective capsulotomies formed in an anterior and a posterior part of the capsule.

Abstract: An intraocular lens for insertion into the capsular bag of an eye contains an optic, an outer periphery, and an outer support structure. The optic has a periphery and centered about an optical axis. The outer periphery is disposed about the optic and configured to engage an equatorial region of the capsular bag of an eye. The outer support structure is disposed along the periphery and spaced from the optic with voids outer support structure and the optic. The intraocular lens further comprises a first intermediate member and a weakened region disposed along the outer periphery between the outer support structure and the first intermediate member. The first intermediate member operably couples the optic and the outer support structure. The weakened region is attached to, and configured to provide relative motion between, the outer support structure and the first intermediate member in response to the ciliary muscle of the eye.

Abstract: An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The region of contact between the optic and the haptic extends into the edge of the optic, similar to the interface between a bicycle tire and the rim that holds it in place. The haptic may be stiffer than the optic. The haptic may have the same refractive index as the optic. The haptic may include a saddle-shaped portion in contact with the adjustable optic, with a convex profile along an optical axis; and a concave profile in a plane perpendicular to the optical axis.

Abstract: A multi-component accommodating intraocular lens (A-IOL) for implantation in a capsular bag of an eye having an optical axis, includes an anterior optical element and a posterior component that are connected by at least one compressible haptic. The compressible haptic, by definition, has a deformation feature that is resiliently deformable. The deformation feature allows the nominal overall diameter of the A-IOL to dynamically vary over a selected range in response to a capsular bag dimension that is different than that of an average population value, or in response to a change in the size and/or shape of the capsular bag due to post-operative capsular bag shrinkage, without substantially changing the separation distance between the anterior and posterior components of the A-IOL absent an intended accommodating force. Methods are also disclosed.

The haptic is a high modulus skeletal frame, and may be assembled with lower modulus material. An eyelet may be provided on the lens allowing a cleat on the haptic to firmly attach to the optic.

Abstract: An intraocular lens (IOL) includes an optic for focusing light, an outer ring for supporting the optic in a capsular bag of an eye and a plurality of radially spaced apart, elongated intermediate members connecting the optic to the outer ring. The intermediate members are configured to convert radial forces exerted by the capsular bag on the support ring into axial movement of the optic, allowing a presbyopic patient to more effectively focus on near objects. The outer ring is preferably contoured to conform to the portion of the capsular bag between the anterior and posterior zonules, and has sufficient axial thickness to contact both sets of zonules. In addition, the edge of the ring includes at least one sharp edge corner to prevent epithelial cell growth toward the optic. In addition, the outer ring may include weakened areas configured to allow consistent and repeatable deformation in response to compressive forces.

In one embodiment, the side region has a first location disposed closer to the optic than the pincer gap and a second side region disposed further from the optic than the pincer gap. The distance of both side regions to the central-most portion of the pincer gap is substantially identical.

Abstract: A phakic refractive lens which conforms to the structure of the eye, particularly to the ciliary sulcus, is disclosed. This lens minimizes stresses of the lens on the interior structure of the eye and eliminates excessive vaulting of the lens which tends to deform the shape of the eye and/or structures in the eye. The lenses comprise an optical body and at least one haptic body. The haptic body(ies) is made up of a first portion adjacent to the optical body, a second portion which extends outwardly from the first haptic portion, and a transition zone between the first and second haptic portions (for example, a groove or score line in the lens surface) which permits the second haptic portion to conform to the shape of the ciliary sulcus of the eye.

Abstract: A film frame for an IOL has been developed which has the advantages of being lightweight, non-irritating, easily surgically implanted, aesthetically pleasing, and containing plate haptics. This IOL works in the anterior or posterior chamber of the eye for phakic or aphakic lenses and especially in the anterior chamber for phakic refractive lenses where thinner is better and long-term stability is required. This deformable IOL frame is a haptic system based on a high modulus harder material shaped skeletal frame or plate haptic assembled with low modulus softer elastomeric hinged zones. The rigid frame or haptic in combination with the soft hinges will ensure that the lens is ideally situated in the anterior chamber angle of the eye. Additionally, the soft elastomer can be extended to provide for a softer atraumatic contact point or ‘toe’ in the eye tissue.

Abstract: An accommodating intraocular lens to be implanted within the natural capsular bag of a human eye from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant. During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis about haptics on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule of the bag in which the posterior capsule is stretched rearwardly.
