Abstract: A foldable lens comprises an outer refractive surface portion comprising a first plurality of convexly curved refractive profile regions having positive optical power to converge light energy with refraction toward a focus on the retina. The convexly curved refractive profile regions of the outer region may correspond to at least about a quarter of the refractive power of the lens, such that the lens thickness is decreased substantially and the folded lens can fit through a small incision. The outer refractive surface portion focuses light with refraction, in focus images viewed through the outer portion of the lens can appear sharp to the patient. The outer refractive surface portion also comprises a second plurality of concavely curved refractive profile regions having negative optical power disposed between the first plurality, so as to diverge the light energy substantially away from the focus on the retina, such that visual artifacts are inhibited.

Abstract: An intraocular lens includes an optic, which includes a first lens having a first optical axis for alignment with an optical axis of the human eye having a macula; and a second lens having a second optical axis. The second optical axis and the first optical axis enclose an angle between 0.5 and 10 degrees. The first and second lens are arranged next to one another in a direction transverse to the first optical axis to provide no overlap in a direction along the first optical axis such that the first lens and the second lens each, independent from one another, image onto the macula of the eye. The angle and a direction of the second optical axis are chosen such that the second lens images onto a functional part of the macula of the human eye, which functional part is not compromised by a defect, such as a scotoma.

Abstract: An intra-ocular artificial lens with variable optical strength, having at least two optical elements, at least two of which are movable relative to each other in a direction extending transversely of the optical axis, wherein the optical elements have a form such that in different positions of the movable optical elements the artificial lens has a different optical strength, wherein the artificial lens has a fixed, positive optical basic strength wherein the variable optical strength caused by the relative movement of the movable elements is added to obtain the total optical strength of the artificial lens. Providing a different form results in the possibility of incorporating the greatest optical power in one of the optical elements. This optical element can then be optimized for the desired optical properties. The remaining optical element or the remaining optical elements can then be dimensioned for variation of the optical strength.

Abstract: An intraocular lens for providing accommodative vision to a subject includes a frame disposed about an optical axis, a first optical element, a second optical element, and a connecting element operably coupling the frame to the optical elements. The frame comprises an anterior frame element and a posterior frame element.

Abstract: A supplemental intraocular lens is provided for implantation in the eye to modify the lens system of the eye comprising the cornea and the natural lens or an intraocular lens already implanted in the eye, to create a modified lens system having teledioptic or other diffractive capabilities to correct for macular degeneration. To create the teledioptic lens system, the supplemental intraocular lens has substantially no refractive power except for a high minus lens portion at its center. The supplemental intraocular lens, when implanted on the natural or previously implanted artificial lens in the eye and used without an external lens, allows light rays entering the eye onto the retina of the eye as they would without the supplemental intraocular lens, thus providing unmagnified and peripherally unrestricted vision.
