Patent number: 9833136Abstract: The present application discloses methods and systems to track the anterior segment while establishing a position of the delay which will permit good control of the placement of anterior segment structures. This allows accurate dewarping by maximizing the amount of corneal surface that is imaged as well as reducing or eliminating overlap between real and complex conjugate images present in frequency-domain optical coherence tomography. A method to dewarp surfaces given partial corneal surface information is also disclosed.Type: GrantFiled: December 18, 2014Date of Patent: December 5, 2017Assignee: Carl Zeiss Meditec, Inc.Inventor: Homayoun Bagherinia

Patent number: 9820883Abstract: A method and delivery system are disclosed for creating an aqueous flow pathway in the trabecular meshwork, juxtacanalicular trabecular meshwork and Schlemm's canal of an eye for reducing elevated intraocular pressure. Pulsed laser radiation is delivered from the distal end of a fiber-optic probe sufficient to cause photoablation of selected portions of the trabecular meshwork, the juxtacanalicular trabecular meshwork and an inner wall of Schlemm's canal in the target site. The fiber-optic probe may be advanced so as to create an aperture in the inner wall of Schlemm's canal in which fluid from the anterior chamber of the eye flows. The method and delivery system may further be used on any tissue types in the body.Type: GrantFiled: May 21, 2001Date of Patent: November 21, 2017Inventor: Michael S. Berlin

Patent number: 9795452Abstract: A treatment apparatus for a subretinal injection into an eye includes a 3D imaging device configured to generate a 3D image of a retina and a choroid of the eye. The apparatus has a planning device for inputting at least one set position for an injection instrument to be used for the injection. The set position is a location indication in the 3D image. The apparatus includes a 2D imaging device to generate a surface image of the retina and supplement the image to form a supplemented image, via the 2D imaging device ascertaining in the surface image at least one location which, in the surface image, corresponds to the at least one set position indicated in the 3D image, and inserting into the surface image at least one mark that corresponds to the ascertained at least one location. A display device displays the supplemented image.Type: GrantFiled: November 17, 2016Date of Patent: October 24, 2017Assignee: Carl Zeiss Meditec AGInventors: Thomas Hartkens, Abouzar Eslami

Patent number: 9782253Abstract: A method of treating a cataractous lens of a patient's eye includes generating a light beam, deflecting the light beam using a scanner to form a treatment pattern, delivering the treatment pattern to the lens of the patient's eye to create a plurality of cuts in the form two or more different incisions patterns within the lens to segment the lens tissue into a plurality of patterned pieces, and mechanically breaking the lens into a plurality of pieces along the cuts. A first incision pattern includes two or more crossing cut incision planes. A second incision pattern includes a plurality of laser incision each extending along a first length between a posterior and an anterior surface of the lens capsule.Type: GrantFiled: December 19, 2014Date of Patent: October 10, 2017Assignee: Optimedica CorporationInventors: William Culbertson, Barry Seibel, Neil Friedman, Georg Schuele, Phillip Gooding

Patent number: 9700461Abstract: Systems, devices, and methods for treating a glaucomatous eye are provided. Embodiments may provide a treatment probe for treating an eye of a patient. The treatment probe may have an elongate body with a contact surface at a distal end of the elongate body. A treatment fiber or light source may be housed in the treatment probe and may be configured to direct treatment energy from the contact surface. The contact surface may be configured to couple to a surface of the eye to deliver the energy into the target area. In many embodiments the contact surface may have a convex configuration with a rounded outer shape and edge that facilitates the sweeping of the probe surface across the eye during treatment delivery. In some embodiments the probe may be swept in arc motions while delivering treatment energy to the eye.Type: GrantFiled: June 25, 2015Date of Patent: July 11, 2017Assignees: IRIDEX Corporation, National University Hospital (Singapore) PTE Ltd, National University of SingaporeInventors: David Buzawa, Paul T.
