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: 9089397Abstract: Apparatus and methods for preventing prolapse of iris tissue through a surgical opening in the eye during an ophthalmic surgery. A flexible biocompatible polymeric shield is inserted into the anterior chamber of the eye, placed in position overlying the iris adjacent a surgical opening into the anterior chamber and is thus between the iris tissue and the surgical opening. As pressure inside the anterior chamber increases during the surgery, anterior movement of the iris toward any surgical opening in response to such pressure, also moves the shield anteriorly, such that the shield remains between the iris and the surgical opening. Thus, the shield blocks the surgical opening and prevents movement of eye material to and through the surgical opening. The surgical opening can still be accessed by surgical tools and materials from outside the eye by inserting such articles through the surgical opening and pushing such articles past the shield.Type: GrantFiled: October 1, 2012Date of Patent: July 28, 2015Inventor: Gerald Paul Clarke

Patent number: 9072601Abstract: An intraocular lens insertion device having a novel configuration, capable of more accurately arranging front and back surfaces of an intraocular lens in a proper direction. The intraocular lens insertion device is adapted in such a manner that the intraocular lens is set on a stage in a state placed flat with a pair of haptics extended facing front and back sides in a movement direction by a plunger. Also, an interfering acting part is provided to an insertion tube part, and the interfering acting part interferes with the haptic, which is extended facing the front side in the movement direction of the intraocular lens moved by the plunger, to apply on the haptic an external force toward the back side in the movement direction. Thus, the interfering acting part curves and deforms the haptic to a side approaching an optical portion.Type: GrantFiled: October 22, 2009Date of Patent: July 7, 2015Assignee: KOWA COMPANY, LTD.Inventors: Masayoshi Tanaka, Kazuharu Niwa, Yasuhiko Suzuki

Publication number: 20150141801Abstract: Specific embodiments of the invention are directed to improved surgical procedures involving the use of processed non-visual three-dimensional data (i.e. diagnostic scan data) to provide a surgeon with additional guidance (i.e. more than that generally obtained from visual observation of the working area) concerning the distance separating a working end of a surgical instrument and the posterior portion of a target tissue. Separation information may be used to aid the surgeon in minimizing the risk of unintended penetration of adjacent tissue with the working end of the instrument. Some embodiments provide for the visual and/or auditory conveyance of distance information to the surgeon. Additional embodiments provide for overlaying visual representations of selected three-dimensional structure information (e.g. depths of troughs cut into the lens) with the real surface feature images viewed by the surgeon.Type: ApplicationFiled: December 12, 2014Publication date: May 21, 2015Applicant: VANTAGE SURGICAL SYSTEMS, INC.Inventors: Hubschman P.
