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: Intraocular lenses include a lens body sized and adapted for placement in a mammalian eye and having a plurality of different optical powers, and a movement assembly joined to the lens body and adapted to cooperate with the mammalian eye to effect accommodating movement of the lens body in the eye. Such intraocular lenses provide enhanced accommodation relative to the accommodation attainable using a single optical power IOL adapted for accommodating movement.

Abstract: An intraocular lens for use in a mammalian eye includes an optic adapted to focus light toward a retina of the mammalian eye and, in cooperation with the mammalian eye, to provide accommodation, the optic being adapted to have a first configuration to provide substantially a single optical power and a second configuration to provide a plurality of different optical powers.

Abstract: An aspheric soft intraocular lens, having an optical power surface, which may have multiple radii portions or aspherical portions, as well as spherical portions, intended to replace the crystalline lens of a patient's eye, in particular after a cataract extraction. Such an aspheric soft lens is molded in a coined mold. A pair of core pins, positioned within the mold cavity during the lens forming process, will produce a pair of haptic-mounting holes within the lens. As the lenses are subsequently tumbled to remove flash, indentations will form adjacent to the haptic-mounting holes. These indentations allow for tangential attachment of the haptic to the lens which, in turn, enables maximum flexibility without exceeding the width of the optic.

Abstract: Multifocal lens provided with a reading part disposed near the bottom part and another lens, such as a distance lens, near the top part. According to the invention, the outer limit of the reading part lies on or within the (outer) radius RV of the remaining part of the lens. This means that no thickening is needed for the reading part, and a particularly gradual transition between reading and distance part can be provided.

Abstract: An intraocular multifocal lens has no definite line between near, far, and/or intermediate power lens areas, and substantially no distortion. A human or animal can use the lens with no need for it to translate. The lens preferably has substantially circular, substantially concentric, lens areas in order from the center, far, intermediate, and near. The multifocal zone preferably is about 2.5-3.5 mm in diameter for all adults. The lens can be made by mechanically acting on a single vision lens (having a predetermined near prescription) using a spinner shaft mounting the lens, and a rotating dish covered by a taut fabric.

Abstract: A multifocal ophthalmic lens, having outer annular zones with vision correction powers less than a far vision correction power of the patient, is disclosed. These additional annular zones come into play, when the pupil size increases under dim lighting conditions, to thereby compensate for the near-vision powered annular zones. The net effect of the additional near vision annular zones and the additional annular zones having power less than the far vision correction power is to shift the best quality image from in front of the retina to an area on the retina of the eye, to thereby reduce halo effects and improve image contrast.
