Patent number: 7998199Abstract: A method of anchoring an accommodating intraocular lens assembly in the posterior chamber of an eye includes the steps of, (1) introducing the first haptic portion, which includes a first anchor portion projecting therefrom, into the posterior chamber of the eye until the first anchor portion is anchored in the scleral wall at a desired location; and (2) moving the second haptic portion, which comprises a second anchor portion projecting therefrom, until the second anchor portion is anchored in the scleral wall on the opposite side of the lens from the first anchor portion and the lens structure is in contact with the collapsed natural lens, whereby the collapsed natural lens capsule will be prestressed and deform the lens body relative to and substantially independently of the haptics element in relation to the force the capsular unit applies directly or indirectly to the lens body along the optical axis.Type: GrantFiled: October 18, 2010Date of Patent: August 16, 2011Assignee: Nulens, Ltd.Inventor: Joshua Ben Nun

Patent number: 7976520Abstract: Eye wall anchored fixtures each including at least one elongated anchor member for driven lengthwise insertion into an eye's eye wall in a transverse direction to its thickness for supporting an intraocular device in the eye's vitreous cavity. Fixtures are preferably anchored in circumferential incisions in a human adult eye's pars plana preferably 3.5 mm posterior to its corneal limbus, and perpendicular to a circumferential incision. The fixtures are either generally L-shaped with a single elongated anchor member designed for withdrawal from an eye wall or self-anchoring thereinto, or generally T-shaped with a pair of oppositely directed self-anchoring elongated anchor members for sealing a throughgoing incision. Intraocular devices can be designed for intraocular drug delivery, for acquiring intraocular physiological measurements, and the like.Type: GrantFiled: July 11, 2006Date of Patent: July 12, 2011Assignee: Nulens Ltd.Inventor: Joshua Ben Nun

Patent number: 7220279Abstract: An accommodating lens assembly having an optical axis and being adapted to be implanted in a posterior chamber of an eye having a capsular unit located therein. The assembly includes a rigid haptics element adapted to secure the assembly within the posterior chamber outside said capsular unit. The element is transparent at least in a region around the axis. The assembly further includes a resilient body adapted to operate as a lens having a curved surface when pressed up against the region of the haptics element by an axial force applied thereto by the capsular unit.
