Publication number: 20130268070Abstract: An accommodating intraocular lens is provided in which a deflectable lens element is anchored to a substrate along its optical axis to define a fluid filled space. Fluid-filled haptics disposed in fluid communication with the space vary the fluid volume in the space responsive to forces applied by the ciliary muscles, thereby causing the periphery of the lens element to deflect relative to the substrate and changing the optical power of the intraocular lens.Type: ApplicationFiled: June 4, 2013Publication date: October 10, 2013Inventors: Victor Esch, John Scholl, Terry Smiley, Patrick Myall, Bill Evans, Barry Cheskin, Henry Wu

Publication number: 20080015689Abstract: An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens, responsive to forces applied to a haptic portion to the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. Displacement of fluid to the actuator may either increase or reduce the degree of deflection imposed on the lens element by the actuator.Type: ApplicationFiled: July 24, 2007Publication date: January 17, 2008Inventors: Victor Esch, Barry Cheskin, John Scholl, Henry Wu, David Smith, Bill Evans, Patrick Myall, Terry Smiley

Accommodating intraocular lens system utilizing direct force transfer from zonules and method of use
Publication number: 20070088433Abstract: An accommodating intraocular lens is provided having optical parameters that are altered in-situ, wherein an optic portion of the lens includes a lens piston that alters the shape of a lens element of the lens to alter the optical power of the lens, responsive to forces applied to a haptic portion to the lens by contraction of the ciliary muscles. Forces applied to the haptic portion are transferred hydraulically to cause the lens to become more or less accommodated. The haptic portion is retained in a fixed unaccommodated state during an initial healing period following implantation to facilitate affixation of the haptic portion to the capsule.Type: ApplicationFiled: October 17, 2005Publication date: April 19, 2007Applicant: PowerVisionInventors: Victor Esch, Terry Smiley, Barry Cheskin, Patrick Myall, Bill Evans, Henry Wu, John Scholl -

Patent number: 6533764Abstract: Apparatus for instilling a medicament into an eye includes a housing having a longitudinal axis and a chamber disposed in the housing for containing a medicament. A nozzle is provided for instilling a dose of medicament into an eye and an actuator meters doses of medicament from the chamber to the nozzle and forces each metered dose through the nozzle upon axial displacement of the actuator along housing longitudinal axis. A spring causes the axial displacement of the actuator upon release of the spring from a compressed state. A collar disposed for rotation about the housing longitudinal axis is provided by compressing the spring by twisting the collar about the housing longitudinal axis and a trigger disposed in a housing is provided for releasing the compressed spring.Type: GrantFiled: November 6, 2000Date of Patent: March 18, 2003Assignee: Allergan, Inc.Inventors: David S.

Patent number: 6078269Abstract: A wireless, battery-operated detection system of a plurality of RF-interconnected detectors is operable over a CSMA-type network and intended to detect the occurrence of a local phenomena and transmit at least one signal to at least one other detector to remotely sound an alarm. Each detector includes a sensor for sensing local phenomena, a transmitter for transmitting RF messages indicative of the phenomena, a receiver for receiving the RF messages, an alarm circuit for sounding an audible alarm indicative of the phenomena and a controller operable to control the mode of operation of each detector, wherein each controller is operable to control all the detectors in the system in response to a stimulus and to control multiple and conflicting signals transmitted among the detectors. The controller includes a prioritization circuit for determining the relative priority of the received RF signals and stimuli indicative of a particular condition to enable the appropriate mode of operation.Type: GrantFiled: November 10, 1997Date of Patent: June 20, 2000Assignee: Safenight Technology Inc.Inventors: Scott Markwell, David L.
