  • Patent number: 11079614
    Abstract: The invention provides an improved rotationally stabilized contact lens design and method of designing such a lens which minimizes stabilization time of the lens while maximizing the lens on-eye comfort. The lens and the method of designing the lens further improves upon an earlier method which utilizes and combines non-circularity and thickness differential aspects which results in equivalent or minimized stabilization time, ease of insertion and manufacturability as well as maximum comfort that is improved over that of what either aspect can achieve independently. This further improvement of stiffness profile is achieved by optimizing and selectively addressing thickness differential both diametrically and circumferentially in a non-round lens design.

    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.
