Patent number: 9498326Abstract: Disclosed is an injector which comprises an injector housing having a longitudinal axis and an injection probe disposed along the longitudinal axis. The injector further comprises an intraocular lens disposed in the housing. The intraocular lens comprises first and second interconnected viewing elements, and the optical axes of the first and second viewing elements are substantially aligned. The optical axes are substantially orthogonal to the longitudinal axis of the housing. The injector further comprises a lens carrier which engages one of the viewing elements. The viewing elements are moveable in response to longitudinal movement of the lens carrier relative to the injector housing. The longitudinal movement causes both (i) the optical axes to be displaced relative to each other and (ii) the viewing elements to be disposed substantially on the longitudinal axis of the injector housing.Type: GrantFiled: March 6, 2012Date of Patent: November 22, 2016Assignee: Visiogen, Inc.Inventor: George Tsai

Patent number: 9421089Abstract: Disclosed are accommodating intraocular lenses for implantation in an eye having an optical axis. In certain embodiments, an intraocular lens includes an anterior optic, a posterior optic, and a support structure configured to move the optics relative to each other along an optical axis between an accommodated state and an unaccommodated state. In certain embodiments, at least a portion of the support structure can be modified in situ to alter reaction forces between the support structure and at least one structure of the eye. In certain embodiments, a refractive property of one of the anterior or posterior optics can be modified in situ while leaving the refractive properties of the remaining one of the anterior or posterior optics substantially unaffected. Additional embodiments and methods are also disclosed.Type: GrantFiled: July 1, 2011Date of Patent: August 23, 2016Assignee: VISIOGEN, INC.Inventor: Gholam-Reza Zadno-Azizi

Patent number: 9095426Abstract: Disclosed is an apparatus for compacting an intraocular lens. The apparatus comprises a lens compactor having a first configuration for retaining the intraocular lens in an unstressed condition and a second configuration in which the compactor stresses the lens into an at least partially compacted condition without advancing the lens along an injection axis of the compactor. The compactor accomplishes this by applying a compacting force in a direction generally orthogonal to the optical axis of the lens. The compactor is responsive to a compactor actuator that is movable by a user to change the compactor from the first configuration to the second configuration. Additional apparatus and methods are disclosed as well.Type: GrantFiled: August 24, 2007Date of Patent: August 4, 2015Assignee: Visiogen, Inc.Inventors: Ian Ayton, Scott Evans, Tuan Nguyen

Patent number: 8784485Abstract: An injector for inserting an intraocular lens into an eye includes a lumen. The lumen can include a terminal portion at a distal end and a proximal portion juxtaposed with the terminal portion. An injector plunger can be disposed within the lumen for generating a driving force on the intraocular lens. The injector can include a lens frictional force that has a first value when the lens is at a first location within the proximal portion and a second value when the lens is at a second location within the terminal portion. The first value can be smaller than the second value. In some embodiments, the lens frictional force increases abruptly from the first value to the second value as the lens approaches the distal end of the lumen.Type: GrantFiled: April 17, 2013Date of Patent: July 22, 2014Assignee: Visiogen, Inc.Inventors: George Tsai, Tuan Anh Nguyen, Phu Nguyen, Scott Evans
