Method Of Manipulating Parts Of Intraocular Lens Structure For Implantation Patents (Class 623/907)
  • Patent number: 9962255
    Abstract: The novel design of the one piece self-locking scleral buckle eliminates the need for a separate tire, band and sleeve by incorporating the band with the tire and making the device self-locking so the sleeve is no longer necessary. As one piece of silicone replaces the need for three separate pieces of silicone scleral buckling surgery is simplified thus making the procedure faster, safer and more efficient. The novel design of the scleral buckle placement instrument allows the surgeon to more firmly grasp the silicone material making the procedure faster and more efficient.

  • Patent number: 7503938
    Abstract: An intraocular lens (IOL) system includes an optic, a pair of haptics located on sides of the optic, and hinge portions at each of the optic haptic junctions. The hinge portions have stressed and non-stressed configurations. One or more restraining elements are provided to maintain the stressed state configuration of the hinge portion during implantation and during a post-operative period during which the capsular bag of the eye heals about the lens. The restraining elements are thereafter removable, preferably via a non-surgically invasive manner, e.g., via dissolution or laser light. Removal of the restraining elements allows anteriorization of the optic as the lens assumes a non-stressed configuration during accommodation. The ciliary body and lens may then interact in a manner substantially similar to the physiological interaction between the ciliary body and a healthy natural crystalline lens.

  • Publication number: 20030033013
    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.

  • Patent number: 6425917
    Abstract: A film frame for an IOL has been developed which has the advantages of being lightweight, non-irritating, easily surgically implanted, aesthetically pleasing, and containing plate haptics. This IOL works in the anterior or posterior chamber of the eye for phakic or aphakic lenses and especially in the anterior chamber for phakic refractive lenses where thinner is better and long-term stability is required. This deformable IOL frame is a haptic system based on a high modulus harder material shaped skeletal frame or plate haptic assembled with low modulus softer elastomeric hinged zones. The rigid frame or haptic in combination with the soft hinges will ensure that the lens is ideally situated in the anterior chamber angle of the eye. Additionally, the soft elastomer can be extended to provide for a softer atraumatic contact point or ‘toe’ in the eye tissue.
