Patent number: 10238544Abstract: In certain embodiments, marking a lenticule includes controlling a focus of pulsed laser radiation having ultrashort pulses. A lenticule marking is created in a cornea of an eye with the pulsed laser radiation to mark the lenticule. The lenticule is then created in the cornea with the pulsed laser radiation.Type: GrantFiled: June 7, 2012Date of Patent: March 26, 2019Assignee: Wavelight GmbHInventors: Jörg Klenke, Katrin Skerl, Theo Seiler

Patent number: 10195084Abstract: According to certain embodiments, a method for laser cutting treatment of a human eye comprises: determining position information of a pupil center of the eye in relation to a point of minimal corneal thickness in an undeformed state of the eye; locating the point of minimal corneal thickness in a flattened state of the eye, in which the eye is deformed by contact with a patient adapter of a laser device; and aligning a pulse firing pattern for laser radiation pulses of the laser device, based on a position of the located point of minimal corneal thickness and the determined position information. In embodiments, the pulse firing pattern represents, for example, a lenticular or doughnut-shaped intracorneal tissue volume which is to be removed from the cornea of the eye.Type: GrantFiled: June 3, 2016Date of Patent: February 5, 2019Assignee: Novartis AGInventors: Theo Seiler, Christof Donitzky, Peter Riedel, Jörg Klenke

Patent number: 10058453Abstract: In certain embodiments, refractive correction includes controlling a focus of pulsed laser radiation having ultrashort pulses. A channel is created with the pulsed laser radiation to facilitate separation of the lenticule from the eye. A posterior incision is created with the pulsed laser radiation to form a posterior side of the lenticule. An anterior incision is created with the pulsed laser radiation to form an anterior side of the lenticule.Type: GrantFiled: April 24, 2012Date of Patent: August 28, 2018Assignee: Wavelight GmbHInventors: Theo Seiler, Katrin Skerl, Jörg Klenke

Patent number: 9660412Abstract: A method and system for generating femtosecond (fs) ultraviolet (UV) laser pulses enables stabile, robust, and optically efficient generation of third harmonic fs laser pulses using periodically-poled quasi-phase-matched crystals. The crystals have different numbers of periodically poled crystalline layers that enable a long conversion length without back-conversion and without a special phase-matching direction. The fs UV laser may have a high conversion efficiency and may be suitable for high power operation.Type: GrantFiled: January 27, 2016Date of Patent: May 23, 2017Assignee: Novartis AGInventors: Klaus Vogler, Joerg Klenke, Johannes Loerner

Publication number: 20140236135Abstract: In certain embodiments, a device configured to perform epithelial removal comprises a laser device and a control computer. The laser device can separate the epithelium from the Bowman's layer of an eye using pulsed laser radiation having ultrashort pulses. The laser device includes controllable components that control a focus of the pulsed laser radiation. The control computer controls the controllable components to focus the pulsed laser radiation at one or more epithelial cell layers of the epithelium to photodisrupt at least a portion of the epithelial cell layers.Type: ApplicationFiled: November 10, 2011Publication date: August 21, 2014Applicant: WAVELIGHT GMBHInventors: Christof Donitzky, Joerg Klenke

Patent number: 8715272Abstract: A device for machining the human cornea with focused laser radiation includes controllable components for setting the location of the radiation focus, a control computer for controlling these components, and also a control program for the control computer. The control program contains instructions that have been designed to bring about, upon execution by the control computer, the generation of incisions in the cornea in accordance with a predetermined incision figure, the incision figure defining a corneal bed, a flap situated on the bed and also at least one tissue strip situated in the region of the peripheral edge of the flap between the bed and the flap and extending along the edge of the flap. After the flap has been folded away, the tissue strip has to be removed and enables a creaseless post-ablative close fitting of the folded-back flap against the surface of the bed. In this manner, microstriae which may impair the visual capacity can be avoided.Type: GrantFiled: April 18, 2013Date of Patent: May 6, 2014Inventors: Christof Donitzky, Jörg Klenke, Christian Wüllner
