Patent number: 8663235Abstract: This invention describes a simple intraocular lens (IOL) design with a removable optic, which can be inserted in and removed from a haptic device. In this haptic the anterior and posterior capsules are sealed in order to have a perfect control over the lens epithelial cell proliferation which is thereby restricted to the peripheral part of the capsular bag. Additionally, a ring caliper is described as new surgical device to allow a precise sizing and centration of the anterior capsulorhexis. The removable optic allows repeatable correction of the eye focusing over time in case the optical parameters of the eye have changed due to a variety of factors. By separating the optic part from the haptic part, the optic part can easily be manufactured in any shape matching the optical errors of the eye, including the ocular aberrations. The optic part can be manufactured out of any biomaterial restoring ocular accommodation.Type: GrantFiled: April 20, 2005Date of Patent: March 4, 2014Inventor: Marie-José B. Tassignon

Patent number: 8657876Abstract: Apparatus and methodology for inserting an intraocular lens (IOL) into an eye. The apparatus includes a cartridge for holding an IOL and a handpiece with a body member for receiving the cartridge, an injector rod that is receivable by the body member, and a drive mechanism that longitudinally oscillates the injector rod in the body member when a rotational force is applied about a longitudinal axis in a single direction.

Patent number: 8623037Abstract: A system and method is disclosed for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The system and method comprises a surgical tool comprising a surgical blade for making incisions in the sclera of an eye. When a surgeon places the surgical blade on the sclera of the eye a pressure sensor in the surgical tool determines whether there is sufficient pressure between the surgical tool and the sclera of the eye for the surgical tool to operate properly. The surgeon activates the surgical tool to cause the surgical blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the surgical blade is rotated back out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.Type: GrantFiled: November 30, 2006Date of Patent: January 7, 2014Assignee: Refocus Ocular, Inc.Inventors: Ronald A. Schachar, Donald P. Cudmore

Publication number: 20130345713Abstract: A system for easily transferring an intraocular lens (IOL) from a lens case to an inserter, and then into a patient's eye. The lens case has a transfer mechanism therein which retains the IOL until engagement with the inserter. The transfer mechanism may include jaws having a closed configuration for retaining the IOL and an open configuration for releasing the IOL. Engagement of the inserter with the lens case automatically opens the jaws and transfers the IOL to the inserter. The IOL is transferred into a load chamber of a nosepiece rotatably coupled to a handpiece. After transfer of the IOL, the nosepiece is rotated from a load position to a delivery position. The IOL may have an optic and a haptic coupled to the optic, and the lens case may be capable of configuring the haptic as desired to facilitate its transfer into an inserter and/or into the eye. For instance, the lens case may fold one or both of the haptics over the optic.Type: ApplicationFiled: May 6, 2013Publication date: December 26, 2013Inventors: Mark Cole, Rod Peterson, Nick Martin, Steven Anderson

Publication number: 20130338676Abstract: Provided is technology which can prevent plunger deformation and further stabilize an intraocular lens insertion operation, even when an insertion tube section of an intraocular lens insertion apparatus has been further reduced in terms of the diameter thereof and has been made flatter. The intraocular lens insertion apparatus includes: a tip end region where a plunger comes into contact with an intraocular lens main body and an intraocular lens holding section; and a bar-shaped section extending from the rear end of this tip end region to the rear of the plunger. The bar-shaped section has a fixed thickness in the direction of the optical axis of the intraocular lens, and has an increasing thickness in a portion where the distance from the tip end of the tip end region is equal to or greater than a predetermined distance in a direction perpendicular to the optical axis direction and perpendicular to the plunger advancement direction.Type: ApplicationFiled: December 1, 2011Publication date: December 19, 2013Applicant: KOWA COMPANY, LTD.Inventors: Akinori Marunaka, Toshihide Tanaka, Yuji Nagura, Shuji Abe

Patent number: 8608753Abstract: A probe for a vitrectomy tool is provided having a vitreous cutter tube having a blunt tip at a distal end and adapted to be coupled at a proximal end to a handpiece of a vitrectomy tool; a retractable outer trocar tube surrounding the vitreous cutter tube having an open distal end with a sharpened edge; and a retraction mechanism coupled to a proximal end of the outer trocar for selectively extending and retracting the outer trocar tube between a first extended position wherein the sharpened edge of the outer trocar is extended beyond the blunt tip of the vitreous cutter tube to facilitate insertion into the eye and a second retracted position wherein the sharpened edge of the outer trocar is retracted behind the blunt tip of the vitreous cutter tube to facilitate safe operation of the probe.Type: GrantFiled: July 6, 2012Date of Patent: December 17, 2013Assignee: Insight Instruments, Inc.Inventors: K. Peter Luloh, Tarek Shawky Hassan, Michael Annen

Patent number: 8603103Abstract: There is provided an intraocular lens insertion device capable of appropriately regulating the motion of a rear supporting portion during a process of moving an intraocular lens, and reducing the possibility of reoperation being required after the intraocular lens is inserted into an eye. An intraocular lens insertion device 1 comprises a main body 2, and a slider 3 and a plunger 4 that are attached to the main body 2. Further, the intraocular lens insertion device 1 is of a preset type in which an intraocular lens 5 is placed inside the main body 2 in advance. The slider 3 includes a first abutting portion 21 for pushing up a supporting portion 7 (rear supporting portion 7a) arranged on a rear side of an optical part 6 with respect to a lens advancement axis A, and second abutting portions 22a, 22b abutting against an outer edge of a rear portion of the optical part 6.Type: GrantFiled: January 5, 2010Date of Patent: December 10, 2013Assignee: Hoya CorporationInventors: Kazunori Kudo, Masahiro Noda

Patent number: 8597283Abstract: An ophthalmologic laser system and an operating method. The laser system includes a laser, a scanner unit, a focusing lens and a beam splitter that directs radiation that reaches the beam splitter from the direction of the area of examination through a confocal aperture orifice onto a detector. The invention also includes a control unit with which a cornea arranged in the examination area can be irradiated by the laser at illumination laser power and detection light can be registered by the detector. The cornea is scanned in three dimensions, in that the cornea is irradiated at multiple points and detection light is registered from there. Based on the detection light, a laser cut in the cornea is identified and the form and/or position of the laser cut calculated. The invention further relates to refractive laser surgery.Type: GrantFiled: November 4, 2009Date of Patent: December 3, 2013Assignee: Carl Zeiss Meditec AGInventors: Mark Bischoff, Manfred Dick, Juergen Ledermann
