Publication number: 20170209257Abstract: An Accommodating Intraocular Lens (AIOL) is disclosed herein, that is comprised of a flexible optic and a flexible haptic rim that conforms to the human eye capsule. The spherical or custom shape of the optic is engineered to be maintained during accommodation through the mechanical/optic design of the implant and the interaction between the implant and the naturally occurring position and actuating forces applied through ciliary muscles/zonules/and capsule as the brain senses the need to increase the diopter change or magnification when an object of fixation approaches the eye. The axial relocation or position of the AIOL may also be further adjusted anatomically to further improve the affect needed to achieve improved accommodation. Optionally, the Accommodating Intraocular Lens (AIOL) is foldable or injectable for delivery of the lens into the eye.Type: ApplicationFiled: April 7, 2017Publication date: July 27, 2017Inventor: Donald C.

Patent number: 6554860Abstract: A refractive anterior chamber iris fixated 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 a relatively narrow arch-like form. Each haptic element is also manufactured to have an inner portion and an outer portion 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 fixation clamp on the outer portion thereof and a central portion located between the outer portion and the inner portion.Type: GrantFiled: May 15, 2000Date of Patent: April 29, 2003Assignee: Bausch & Lomb IncorporatedInventors: Laurent G. Hoffmann, Charles J. Hagemeier, Wilson Hsing, Donald C. Stenger, Eric T. Wilde

Publication number: 20030055499Abstract: A refractive intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably two, three or four equally spaced haptic elements. Each haptic element is of like fluidly varying trapezoidal form to achieve a “propeller-like” appearance. Each haptic element is also manufactured to have an inner portion with a gusset and an outer portion with a contact button 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 is formed to have a relatively low profile and a 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 14, 2001Publication date: March 20, 2003Inventors: Tuan Anh Nguyen, Laurnt G. Hoffmann, Donald C. Stenger

Patent number: 5354268Abstract: A pneumatic pressure delivery system capable of delivering negative pressure (vacuum or suction) or positive pressure with a precise, continuously variable and predictable control of the pressure delivered is disclosed. The method and apparatus includes the capability of electronically adjusting the variation of pressure to follow any desirable functional mathematical relationship of a control signal. The apparatus includes an electronically controlled pressure regulator in which the pressure at the outlet of a regulator acts upon a piston or diaphragm in opposition to a force produced by an electronic controller. The piston or diaphragm is mechanically coupled to a flow control valve such that the valve alters its position to increase or decrease the flow to its outlet in response to the force exerted on the piston or diaphragm.Type: GrantFiled: November 4, 1992Date of Patent: October 11, 1994Assignee: Medical Instrument Development Laboratories, Inc.Inventors: Erik W. Peterson, Donald C. Stenger

Patent number: 4787701Abstract: An assembly for interconnecting a plurality of first contacts disposed in a ribbon array with a plurality of second contacts, also disposed in a ribbon array, includes a plurality of cylindrical radial springs which are split longitudinally along an axial direction of the contacts, each radial spring providing three common lines of contact with the mating first and second contacts so as to precisely align front ends of mating the first and second contacts. The assembly further includes dynamic seals on opposite ends of an alignment insert which contains the cylindrical, radial springs, the dynamic seals preventing foreign matter from entering an interface between front ends of the mating first and second contacts, and also functioning to dampen shock- and vibration-induced displacements of the mating first and second contacts.Type: GrantFiled: November 13, 1984Date of Patent: November 29, 1988Assignee: Raychem Corp.Inventors: Donald C. Stenger, Roger H. Ellis
