    Abstract: A vision correction arrangement is described in which a lens system having variable optical power varies in dependence on the orientation of the user's eye. The vision correction arrangement may be embodied as an intraocular lens implant, or an extraocular device such as spectacles. The intraocular lens implant comprises a fixed lens element (11) and a movable lens (12) element sensitive to the orientation of the eye, so that the optical power of the intraocular lens implant is increased when the user looks downward, and returns to a reduced optical power condition when the user's eye returns to a horizontal gaze. The fixed lens element may have a convex rear surface and a concave front surface, and the second lens element may be pivotally mounted in front of the first lens element, so that downward inclination of the eye causes the second lens element to swing away from the fixed lens element.

    Abstract: An accommodating (re-focusable) intraocular lens (IOL) a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis and respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. Change in accommodation of the IOL is achieved by changing an applanated area of contact between the lenslets in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to the optical portions through the interlocked haptics. When installed in a natural lens capsule after the cataract extraction, the optical power of the IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle.

  • Patent number: 8603166
    Abstract: Disclosed is an intraocular lens assembly provided inside a capsular sac. The intraocular lens assembly according to one embodiment of the present invention includes an intraocular lens and an intraocular lens supporter, and therefore the intraocular lens assembly may be useful to transfer a force to the intraocular lens, inserted inwardly into the capsular sac, to allow the intraocular lens to move like a natural eye lens, the force being generated from the ciliaris muscle and transferred through the zonule of Zinn and the capsular sac.

  • Publication number: 20130317608
    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. The connecting element is configured to convert a first displacement between the frame elements in a direction that is substantially parallel to the optical axis into a second displacement between the optical elements that is substantially perpendicular to the optical axis. The second displacement may be translational and/or rotation. In some embodiments, the optical elements are two varifocal lenses.

  • Publication number: 20130310931
    Abstract: A modular IOL system including intraocular primary and secondary components, which, when combined, form an intraocular optical correction device, wherein the secondary component is placed on the primary component within the perimeter of the capsulorhexis, thus avoiding the need to touch or otherwise manipulate the capsular bag. The secondary component may be manipulated, removed, and/or exchanged for a different secondary component for correction or modification of the optical result, on an intra-operative or post-operative basis, without the need to remove the primary component and without the need to manipulate the capsular bag. The primary component may have haptics extending therefrom for centration in the capsular bag, and the secondary component may exclude haptics, relying instead on attachment to the primary lens for stability. Such attachment may reside radially inside the perimeter of the capsulorhexis and radially outside the field of view to avoid interference with light transmission.

  • Patent number: 8579972
    Abstract: This invention concerns an intraocular artificial lens with variable optical power which lens is comprised of two optical elements which can be shifted relatively to each other in a direction perpendicular to the optical axis wherein the optical elements have such a shape that they exhibit, in combination, different optical powers at different relative positions and positioning means for positioning the optical elements in the eye and driving means for at least one of the optical elements to execute a movement relative to the other optical element and whereby the positioning means provide for forcing the optical elements to a resting position.

  • Patent number: 8579970
    Abstract: A telescopic intraocular lens system comprises a telescopic optical system comprising an anterior optic interconnected with a posterior optic. The optics are substantially aligned on an optical axis of the optical system. The optics are formed from a soft material and the optics are substantially immovable relative to each other along the optical axis in response to accommodative forces of the type observed in the capsular bag of the human eye.

  • Publication number: 20130204364
    Abstract: A vision correction system comprising an intraocular lens having a lens body and one or more haptics is provided. The lens body may be configured to be positioned posteriorly to an iris of an eye and may have a convex anterior surface, a concave posterior surface, and a circumferential edge having a rounded anterior portion and a rounded posterior portion. Haptics may extend at an anterior angle from the lens body and be configured to contact the ciliary sulcus of an eye. The haptics and/or hydrophobic forces between this lens body and a second intraocular lens may secure the lens body in the eye in a relatively fixed position and prevent rotation of the lens over time.

  • Patent number: 8500806
    Abstract: An intraocular lens has a polymeric optic defined by a harder posterior layer and a softer anterior layer. Haptics having a fulcrum attached to the posterior layer and a resistance arm attached to the anterior layer are provided. A bias is provided to the haptic to rotate the haptics about the fulcrum and cause the resistance arm to deform the softer anterior layer about the harder posterior layer to increase the optical power of the lens. As the haptic rotates, it axially displaces the optic anteriorly to additionally increase the optical power. The optical power is adjustable in response to stresses induced by the eye. The haptics are subject to a pre-bias that urges the haptics to rotate or bend about the fulcrum. Temporary restraints are provided to the haptics to retain a stressed shape of the lens against the bias during a post-implantation healing period.
