Abstract: Intraocular lens combinations are provided which include an axially movable primary intraocular lens (IOL) and a substantially fixed compensating IOL. In certain embodiments, the compensating IOL has no corrective power and serves only to inhibit or reduce the risk of posterior capsular opacification (PCO). In other embodiments, the primary IOL has higher corrective power than required by the patient's prescription in order to amplify the accommodation obtained from axial movement, and the compensating IOL has negative corrective power to compensate for the excessive diopter value of the primary IOL. In a preferred method, the primary IOL is implanted in the capsular bag of an eye, and centered about the optical axis. The compensating IOL is then implanted in the capsular bag, sulcus, or anterior chamber and axially aligned with the primary IOL.

Abstract: The present invention is to provide an intraocular lens that may accommodate automatically, including a central optic having an anterior optic connected with the stroke cylinder, a posterior optic connected with the outer core which is connected with the stroke cylinder, thereby enclosing the central optic in an inner periphery. Thus, by change of the inclined angle of the user, or by variation of the external magnetic field, the push force that is exerted on the central optic of the intraocular lens may be regulated, so as to actively control the position of the central optic of the intraocular lens, so that the user may actively control and regulate the refractive power of the eyeball that is implanted with the intraocular lens.

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: This patent represents a deformable artificial intraocular lens for implantation into the human eye. The lens is used for implantation after cataract surgery. The lens optic consists of one smooth optical surface. The second optical surface is a series of annular concentric rings. The rings allow the lens to have extremely thin edges, which reduce glare, halos, and distortion. The extremely thin lens optic along with the thin haptic can be rolled, folded, or squeezed to pass through a small incision (<1.5 millimeters) in the cornea or sclera of the human eye. This lens represents a breakthrough in removal of mass from the lens. The ultra thin lens and haptic design allows the lens to move in the eye providing accommodation for the patient. The lens and haptic design reduces the radial forces on the eye to the point where the naturally occurring pressures in the eye move the lens thus providing accommodation.

Abstract: An accommodative intraocular lens is disclosed. The lens provides multiple focuses as the result of a bi-directional shift along the eye's optical axis, and also minimizes or prevents posterior chamber opacification. The lens includes a first component which consists of an optical body and a haptic body, a second component which is structurally adapted to maintain substantial contact with the posterior surface of the capsular bag of the eye (when implanted in the eye), and a transition zone connecting the first and second components. The method of implanting the lens in the eye and the method of making the lens are also disclosed.

Abstract: An intraocular lens (38) having focusing capabilities permitting focusing movement of the lens (38) in response to normal ciliary muscle movement incident to changes in the distance between the eye and an object under observation is provided. The lens (38) is designed for surgical implantation within the capsule (22) of an eye (10) and includes an optic (40) and a resilient body (46) which cooperate to form a discoid shaped lens (38) that generally conforms to the shape of the natural capsule (22). When distant objects are viewed, the ciliary body (32) is retracted and the capsule (22) flattens, thus causing the lens (38) to likewise flatten, moving the optic (40) posteriorly, closer to the fovea (26). When viewing near objects, the ciliary body (32) contracts, causing the capsule (22) and thus the lens (38) to expand to their original shape, shifting the optic (40) anteriorly, away from the fovea (26).

Abstract: A new lens design and method of implantation uses the change in pupil diameter of the eye concurrent with the changes induced by a contraction of the ciliary muscle during the accommodative reflex, in order to assist in focusing of nearby objects. This new intraocular lens consists of two parts. The posterior part or haptic part is inserted behind the iris and in front of the natural lens or artificial implant. Its main purpose is to participate in the accommodative mechanism and to prevent excessive lateral movement and luxation of the lens. An anterior or optical part is made of flexible material and is placed before the iris. Its diameter is variable but should be large enough to cover the pupillary margins to some degree under various conditions of natural dilation. The anterior and posterior part of the lens are separated by a compressible circular groove in which the iris will settle.

Abstract: Intraocular lenses include an optic adapted to focus light toward a retina of an eye and a movement assembly coupled to the optic. The optic includes a far vision correction power for infinity reduced by a diopter power increment. The movement assembly is adapted to cooperate with the eye to move the optic bidirectionally, that is anteriorly in the eye and posteriorly in the eye, for example, from a neutral resting position in the eye, to effect positive accommodating movement of the optic and negative accommodating movement of the optic, respectively. Methods of inserting such intraocular lenses into an eye are also provided.
