20090018652 | ACCOMMODATING INTRAOCULAR LENSES AND ASSOCIATED SYSTEMS, FRAMES, AND METHODS - 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. | 01-15-2009 |

20100145446 | SOFT INTRAOCULAR LENS - An intraocular lens of the present invention has a substantially circular or elliptical optical lens portion made of a soft material, and an arm-shaped support arm portion attached to outer peripheral edges of this optical lens portion, and out of the peripheral edges of the optical lens portion that are contiguous to both sides in a width direction of a root of the support arm portion, at least one outer peripheral edge has a portion recessed inward from the convex curve. Thus, there is provided a soft intraocular lens that can be inserted into an eye from a further smaller incision, without damaging an optical function as much as possible. | 06-10-2010 |
20100241225 | CURABLE RESIN COMPOSITION FOR INTRAOCULAR LENS, INTRACULAR LENS MATERIAL AND INTRACULAR LENS - A curable resin composition for intraocular lens is provided, the curable resin composition including: (a) a first monomer selected from compounds represented by formula (I); (b) a polyfunctional second monomer; and (c) a radical polymerization initiator: | 09-23-2010 |
20100262234 | Posterior chamber phakic intraocular lens - A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible and permeable material. The lens has a generally circular optic and a plurality of integrally formed, filament-like haptics. The haptics project posteriorly from the optic and contain a raised feature or ridge that is sandwiched between the posterior iris and the zonules when implanted in an eye. Such a construction has a low vaulting force under compression, is size insensitive, provides for a stable lens once implanted in the eye, helps to avoid pupillary blockage and allows for improved aqueous flow around the natural lens. | 10-14-2010 |
20100324674 | Intracapsular Pseudophakic Device - Intraocular devices for use in and attached to the natural lens capsule of an eye are provided. The lens capsule may be maintained in a configuration to avoid post-operative changes that are deleterious to vision. Single or dual optic systems are provided, which may be accommodating. Combinations of devices to obtain dual optic systems are disclosed. | 12-23-2010 |
20110082543 | Methods and Devices for Preventing or Delaying Posterior Capsule Opacification - Several methods for preventing, minimizing, or delaying the incidence of posterior capsule opacification are provided. A first method involves chemically activating the surface of an implantable ocular device, such as an intraocular lens or a capsular tension ring, by grafting a chemical moiety onto the surface of the device, covalently attaching a non-cytotoxic inhibitor compound to the chemical moiety to produce an inhibitor implantable ocular device, and implanting this inhibitor implantable ocular device into the capsular bag of an eye of a patient during extracapsular cataract surgery. Appropriate inhibitor compounds include RGD mimetics, RGD peptides, and flavonoids. A second method involves surface modifying the exterior surface of a capsular tension ring by covalently attaching a mitotic inhibitor, preferably a conjugate of methotrexate and a bovine serum albumin, and implanting this inhibitor tension ring into the capsular bag of an eye of a patient during extracapsular cataract surgery. A third method involves surface modifying the exterior surface of a capsular tension ring by coating or grafting the exterior surface with a charged polyethylamine and implanting this inhibitor tension ring into the capsular bag of an eye of a patient during extracapsular cataract surgery. An implantable ocular device according to the invention, such as an intraocular lens or a capsular tension ring, contains a substrate with a chemical moiety grafted thereon and a non-cytotoxic inhibitor compound covalently bonded to the chemical moiety or contains a substrate modified with a mitotic inhibitor or charged polyethylamine. The inhibitor devices inhibits proliferation and migration of lens epithelial cells on the posterior capsule of the eye of the patient, thereby preventing, minimizing, or delaying the onset of posterior capsule opacification. | 04-07-2011 |
20110264211 | MATERIALS FOR MAKING HYDROPHOBIC INTRAOCULAR LENS - The present invention provides copolymers made up of alkoxyalkyl methacrylate and/or alkoxyalkyl acrylate monomers in combination with one or more additional hydrophobic monomers. The copolymers may be used in the manufacture of intraocular lenses, including both the optic and haptic portions of the lenses. The present invention also provide methods for making intraocular lenses from the copolymers. | 10-27-2011 |
20110270390 | METHOD FOR MANUFACTURING APHAKIC INTRAOCULAR LENS - A method of manufacturing an aphakic intraocular lens that is capable of ensuring every multi-focusing effect more securely, while reducing the impact of aperture changes and lens eccentricity. At least two reliefs whose first order diffracted lights give respective focal distances different from one another are set to overlap with each other in at least a part of an area in a radial direction of the lens, and with respect to every grating pitches of one relief having a maximum grating pitch among the reliefs set up in overlap, grating pitches of another relief are overlapped periodically in order to obtain a relief pattern, so that the resulting relief pattern is formed on a lens surface. | 11-03-2011 |

The optical center of the intraocular lens is decentered with respect to the geometric center of the intraocular lens to align the optical centre of the lens with a visual axis of a pupil of the mammalian eye to improve the visual quality and to prevent an aberration. A plane of the intraocular lens is turned and tilted through a preset angle to point an optic axis of the intraocular lens to the Fovea. | 03-21-2013 |
