  • Publication number: 20150134059
    Abstract: A deformable accommodating intraocular lens (IOL) is disclosed, where the IOL comprises a diffractive kinoform-like grating pattern on one or both of the anterior or posterior surfaces of the deformable IOL. The capsular bag of the eye exerts a distorting force on the IOL, changing its power and allowing for accommodation. The focal length variation obtained by the change in curvature of the refractive surface of the IOL is enhanced by the kinoform-like diffractive grating pattern in combination with the traditional refractive surface. The focal length variation obtained by stretching and shrinking of the diffractive pattern adds considerable power variation independent of the refractive index of the material used to make the IOL.

  • Patent number: 8968399
    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.

  • Publication number: 20140121768
    Abstract: An accommodative lens assembly includes a lens body defining an optic lens, a haptic system, and a wing. The lens body is formed and implanted into an eye in a disaccommodative configuration. The haptic system includes one or more haptics that support the optic lens and transmits forces from an anatomical structure such as a ciliary body of the eye, causing the optic lens to deform into an accommodative configuration. In order to stabilize the optic lens so that the optic lens is not displaced from its implantation site, the wing anchors the optic lens within an anterior capsulorhexis of the capsular bag such that the transmitted forces that deform the optic lens during accommodation do not also displace the optic lens from its implanted position. When implanted, the optic lens is anterior to the capsular bag.

  • Publication number: 20100094412
    Abstract: An improved multifocal design for an ocular implant is provided. This ocular implant can include an accommodating intraocular lens (IOL) and a number of haptics. The accommodating IOL includes a liquid suspended between two optically transparent plates or membranes to form a pressure lens that passes optical energy. The haptics mechanically couple to the IOL in order to position and secure the IOL within the eye. The IOL achieves accommodation by using the eye's ciliary muscles to vary the surface curvature of the liquid. The liquid may have a high surface tension and be surrounded by phobic liquid. Pressure from the ciliary muscles causes fluid to be added from or withdrawn to a reservoir. Increasing/decreasing the internal pressure of the liquid changes the angle (curvature) of the surface thus changing the optical properties of the lens. When the pressure is released the liquid returns to the reservoir. The whole system may be sealed off from the interior of the eye by a membrane/transparent lens.

  • Patent number: 6818017
    Abstract: A high gain lens system for implant into the capsular bag after removal of the natural crystalline lens. A preferred embodiment of the invention comprises a combination of a positive or convex lens and a negative or concave lens. These two lenses are spaced from one another and their relative spacing and respective focal lengths determine their combined focal length. When the lens system is inserted into the capsular bag, two opposed haptic flanges on each side, extend toward the inner radial edge of the bag adjacent the ciliary muscles. When the muscles contract, the bag is stretched thereby compressing the haptic flanges together or at least toward one another. This action cause the two lenses to separate further from each other and the increased spacing between the positive and negative lenses shortens the focal length to permit focusing of objects at near distances. On the other hand, when the muscles relax, the bag relaxes also, the haptic flanges separate and the lenses come closer together.
