Abstract: An accommodating IOL comprises an optic adapted to focus light toward a retina of an eye, and a movement assembly coupled to the eye to provide effective accommodating movement, preferably axial movement, of the optic. At least a portion of the movement assembly is made from a material that is less stiff and/or more resilient than the material used to make the optic. Optionally, an outer ring or support portion made at least partially from either a relatively stiff material such as the material used in the optic or a relatively resilient material such as the material used in the movement assembly is also provided.

Abstract: Ocular implant of the type comprising an optical portion to which there is connected a haptic portion arranged to position the focal axis of the optical portion off-center with respect to the geometric axis of the eye, towards the nasal side, provided for insertion into a phakic eye to correct presbyopia, its optical portion having, at least in its central region (7), a multifocal treatment constituting an addition of from +1 to +3.5 diopters, and its haptic portion (6) ensuring that the focal axis (9) of the optical portion (5) is arranged from 0 to 0.75 mm off-center when the implant is in position in the eye.

Abstract: An accommodating intraocular lens including an optic portion having an outer peripheral edge and two, three or four balanced haptic elements for use to achieve multifocal refractive correction. Each haptic element is formed to have less resistance to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The intraocular lens is designed with specific flexibility characteristics so as to exhibit greater than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression of the intraocular lens.

Abstract: An intraocular lens is provided and includes a deformable optic; a pair of support posts spaced circumferentially about the optic and extending outwardly therefrom; and a pair of retaining elements for securing the lens portion within an anterior chamber of the eye by grasping a portion of an anterior surface of iris tissue. Each retaining element has flexible first and second pincer tips that are normally in an abutting or a close abutting relationship when the retaining element is in a closed position. Each retaining element is secured to the anterior surface by opening the first and second pincer tips and pinching the anterior surface of the iris tissue. The optic is coupled to the retaining elements by disposing the support posts within openings or slots that are defined in the retaining elements. The coupling between the posts and the retaining elements is such that the optic is not only securely held within the anterior chamber but also is easily removable and adjustable.

Abstract: A thin foldable intraocular implant specifically configured for installation into the anterior chamber of a phakic or pseudophakic eye has broad positioning flaps that do not apply any substantial pressure against the wall of the eye. It can be rolled for insertion through a corneal incision as small as 2.75 millimeters. The implant is constituted by a two-layered resiliently flexible membrane having a corrective layer of about 50 to 130 microns and an overall thickness of about 150 to 530 microns, that vaults the iris without contacting it. The optic is constituted by a multi-order diffractive (MOD) structure, and is made of silicone, PMMA, hydrogel or hydrophobic acrylate.

Abstract: An anterior chamber phakic lens made from a foldable, highly biocompatible material that has a very low haptic compression force and low axial displacement, yet is stable in the anterior chamber.

Abstract: A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and a pair of integrally formed, plate-style haptics. The haptics project posteriorly from the optic. A plurality of openings are formed at the intersection of the optic and the haptics, the holes extending all the way through the lens. The distal tips of the haptics are split or forked so as to project anteriorly and posteriorly. The anterior arm is designed to fit against the posterior iris, and the posterior arm is design to be supported in the anterior ciliary sulcus. Such a construction provides for a stable lens once implanted in the eye, helps to avoid pupillary blockage and allows for improved aqueous flow around the natural lens.

Abstract: An anterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and integrally formed plate-style haptics, the haptics containing an opening into which project a pair of pincer arms. the pincer arms are sized and shaped so as to pull away from each other when the lens is folded, and are draw back toward each other when the folded lens is released and allowed to return to its unfolded state. Such movement allows the pincers to gather a small section of the iris so as to hold the lens in place.

The movement assembly is adapted to cooperate with the eye to effect accommodating movement of the optic. The movement assembly includes a plurality of movement members each with a proximal region coupled to the optic and an enlarged distal region. The enlarged distal region may be integral with the proximal region, or may be mechanically coupled thereto.

Abstract: An ophthalmic lens system for improving the vision of a patient comprising first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first ophthalmic lens is biased for distance vision and the second ophthalmic lens is biased for intermediate vision. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient without removal of the natural lens.

Abstract: An intraocular lens assembly including a lens, a haptic, and a leverage arm connecting the lens to the haptic, wherein the leverage arm is adapted to apply a lever force on the lens acting generally along a chord inwards of a perimeter of the lens.

Abstract: An intraocular lens (IOL) corrects vision disorders and prevents the formation of cataracts. The IOL can be inserted in the anterior or posterior chamber of the eye, or can be iris-fixated. The IOL can correct for myopia, hyperopia, presbyopia and/or astigmatism. Additionally, the IOL contains an ultraviolet radiation (UVR) blocker, that absorbs UVR in the 300-400 nm range. The absorption of the UVR allows the IOL to reduce or eliminate cataract formation.

Abstract: A multifocal phakic intraocular lens (10) designed to be placed in a phakic eye to correct various refractive disorders such as myopia, hyperopia, astigmatism and presbyopia. The lens (10) which can be positioned within the eye's anterior chamber (62) or posterior chamber (63), consists of a substantially circular optical section (20) having integrally attached either a circular haptic extension (36) or at least two separate haptic extensions (36). When the lens (10) is positioned in the anterior chamber (62), the haptic extensions fixate the lens (10) between the base of the iris (56) and the cornea (72). When the lens (10) is positioned in the posterior chamber (63), the haptic extensions stabilize the lens (10) between the posterior leaf of the iris (56) and the lens capsule (60). In either position, the lens (10) is continuously bathed with the aqueous humour of the eye.

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.

Abstract: An intraocular lens provides substantially increased depth of focus for accurate near and far vision with an optic much thinner than a natural lens, and the lens being rigid, vaulted posteriorly and adapted for posterior positioning in the capsular bag. The optic is positioned substantially farther from the cornea than a natural lens, so that a cone of light exiting the optic to impinge upon the retina is much smaller than a cone of light from a natural lens. Typically, the optic may be about 1.0 mm thick and its distance from the cornea 7.0-8.0 mm.

Abstract: Intraocular lenses include a reduced size optic adapted to focus light toward a retina of an eye and an at least partially opaque movement assembly coupled to the optic. In one embodiment, the optic has a far vision correction power and the movement assembly is at least partially black and adapted to cooperate with the eye to effect accommodating movement of the optic, preferably upon radial compression by a capsular bag of the eye. The optic preferably vaults anteriorly relative to the movement assembly. Enhanced amounts of accommodation preferably are achieved. Combinations of first and second optics and at least partially opaque movement assembly are also provided.

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.
