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

Patent number: 6755859Abstract: A refractive anterior chamber iris fixated intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably two haptic elements. Each haptic element is manufactured to have an inner portion and an outer free end portion for supporting the optic portion in a patient's eye. The inner portion of each haptic element is preferably permanently connected to the outer peripheral edge of the optic portion. Each haptic element also includes a tissue clasp for secure attachment of the intraocular lens to the non-mobile periphery of the iris of an eye.Type: GrantFiled: May 6, 2003Date of Patent: June 29, 2004Assignee: Bausch & Lomb IncorporatedInventors: Laurent G. Hoffmann, Donald Carrol Stenger

Patent number: 6685741Abstract: An accommodating intraocular lens including an optic portion having an outer peripheral edge and two, three or four balanced haptic elements for use to achieve multifocal refractive correction. Each haptic element is formed to have less resistance 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 intraocular lens is designed with specific flexibility characteristics so as to exhibit greater than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression of the intraocular lens.Type: GrantFiled: July 29, 1999Date of Patent: February 3, 2004Assignee: Bausch & Lomb IncorporatedInventors: Michael T. Landreville, Donald Carrol Stenger

Publication number: 20030004570Abstract: An intraocular lens including an optic portion having an outer peripheral edge and two, three or four balanced looped haptic elements for use to achieve refractive correction. Each looped haptic is formed to have greater resistance 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 intraocular lens is designed with specific flexibility characteristics so as to exhibit less than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression of the intraocular lens.Type: ApplicationFiled: August 13, 2002Publication date: January 2, 2003Inventors: Laurent Hoffmann, Mark Wesley Ross, Donald Carrol Stenger

Publication number: 20020087210Abstract: A refractive intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably two, three or four balanced haptic elements. Each haptic element is of like form to achieve a “propeller-like” appearance. Each haptic element is also manufactured to have an inner portion and an outer tip for supporting the optic portion in a patient's eye. The inner portion of each haptic element is permanently connected to the outer peripheral edge of the optic portion. Each haptic element also includes a contact plate and a central portion located between the contact plate and the inner portion. Each haptic is formed to have greater resistance 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 intraocular lens is so designed to exhibit less than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.Type: ApplicationFiled: September 2, 1999Publication date: July 4, 2002Inventors: DONALD CARROL STENGER, LAURENT HOFFMANN, MARK WESLEY ROSS
