Patent number: 7276544Abstract: A process for producing intraocular lenses (IOLs) capable of absorbing blue light and ultraviolet light using photo curing. Intraocular lenses so produced block blue light and ultraviolet light from reaching the retina of an eye implanted with the IOL. By blocking blue light and ultraviolet light from reaching the retina, the IOL thereby prevents potential damage to the retina.Type: GrantFiled: September 8, 2003Date of Patent: October 2, 2007Assignee: Bausch & Lomb IncorporatedInventors: Yu-Chin Lai, Dominic V. Ruscio, George F. Green

Patent number: 6908363Abstract: A method for polishing targeted areas of an IOL while leaving other areas unpolished such as sharp posterior edges designed to inhibit PCO. In the preferred embodiment, the polishing method utilizes a stream of polishing agent directed at the IOL which is mounted to a holder during the polishing operation. In this manner, only the targeted areas of the IOL polished while the other areas remain unpolished and sharp as intended. The method is suitable for in-line automated IOL manufacturing.Type: GrantFiled: June 27, 2002Date of Patent: June 21, 2005Assignee: Bausch & Lomb IncorporatedInventor: George F. Green

Publication number: 20040230300Abstract: An accommodating intraocular lens system including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more haptic elements. The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more haptic elements. Each haptic element is formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The accommodating intraocular lens system is so designed with specific flexibility characteristics to facilitate axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force.Type: ApplicationFiled: June 18, 2004Publication date: November 18, 2004Inventors: Mark H. Bandhauer, George F. Green, Donald Carrol Stenger, Michael T. Landreville

Publication number: 20040059414Abstract: An intraocular lens for inhibiting PCO and glare includes an optic having a periphery provided with a sharp edge which presses against the posterior capsule wall thereby creating a barrier to LEC migration. While the sharp edge forms a 90° angle, the anterior peripheral surface portion extends along an arc which directs incident light striking the edge of the lens away from the retina.Type: ApplicationFiled: September 25, 2002Publication date: March 25, 2004Inventor: George F. Green

Patent number: 6558420Abstract: An accommodating intraocular lens including a higher diopter positive intraocular lens and a lower diopter negative intraocular lens. The positive intraocular lens includes a positive optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components. The negative intraocular lens includes a negative optic portion having an outer peripheral edge and two or more polyurethane elastomer flexible attachment components. Each flexible attachement component is durable and formed to have specific flexibility characteristics so as to be less resistant to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The subject durable accommodating intraocular lens enables axial displacement of the positive optic portion with respect to the negative optic portion along the eye's optical axis under a compression force.Type: GrantFiled: December 12, 2000Date of Patent: May 6, 2003Assignee: Bausch & Lomb IncorporatedInventor: George F.

Patent number: 6471708Abstract: A packaging system for an intraocular lens and optionally an additive material that can be used to insert a packaged intraocular lens into an eye through a relatively small incision. Methods for inserting an intraocular lens into an eye using such packaging system are within the scope of the present invention.Type: GrantFiled: December 21, 2000Date of Patent: October 29, 2002Assignee: Bausch & Lomb IncorporatedInventor: George F.

Patent number: 6454802Abstract: A surface treated intraocular lens implant for use in the replacement of a cataractous natural lens to prevent posteriror capsular opacification. The surface treated intraocular lens includes one or more proteins, polypeptides, polyamino acids or polyamines bound to the surface of the intraocular lens implant covalently, non-covalently or a combination thereof. The one or more proteins, polypeptides, polyamino acids or polyamines present on the surface of the intraocular lens implant serves to reduce or eliminate residual lens epithelial cell migration within the lens capsule. By preventing residual lens epithelial cell migration, posterior capsular opacification of the intraocular lens implant is thus reduced or eliminated.Type: GrantFiled: August 21, 2000Date of Patent: September 24, 2002Assignee: Bausch & Lomb IncorporatedInventors: Randolph H. Bretton, David P. Vanderbilt, George F. Green

Patent number: 4552816Abstract: The invention discloses a novel process for producing covalently bonded laminated structures composed of polyurethane elastomer and vulcanized rubber layers. As the joining means for covalently bonding the polyurethane elastomer and vulcanizable rubber laminates the process utilizes novel grafted polyurethane joining compositions comprised of polyurethane elastomer, a polyisocyanate, and a hydroxyl containing polybutadiene difunctional linker molecule. In practicing the process of the invention, the grafted polyurethane joining composition is first prepared by means that create covalent chemical bonds between the polyurethane elastomer and a first functional (NCO) group on the polyisocyanate, as well as between a hydroxyl on the polybutadiene difunctional linker molecule and a second functional (NCO) group on the polyisocyanate. This novel grafted polyurethane composition is then used to bond layers of polyurethane elastomer to layers of vulcanizable rubber.Type: GrantFiled: October 30, 1984Date of Patent: November 12, 1985Assignee: Novacor Medical CorporationInventors: Bojana K.
