Publication number: 20210311324Abstract: A device for correcting or mitigating refractive errors in the eye presents a solution in which desired improvements in eyesight are achieved as far as possible without limiting everyday activities and where performing the treatment itself involves minimum risk. The device creates an aperture diaphragm in an eye, and has a control unit for a laser unit, the control unit being designed to control the laser unit to create the aperture diaphragm in a lens of the eye, wherein the aperture diaphragm is used to increase the depth of focus of the eye and is formed by laser-induced lesions which reduce light transmission through a lens aperture region surrounding an aperture opening.Type: ApplicationFiled: July 30, 2019Publication date: October 7, 2021Applicant: ROWIAK GMBHInventors: Holger Lubatschowski, Georg Gerten

Patent number: 10912675Abstract: A glaucoma drainage implant comprising a pressure relief valve via which aqueous humor can be drained. The pressure relief valve has a pressure relief flap which is movably connected with a base plate of the implant, which is to be embedded in a sclera, wherein the pressure relief flap has an actuation area by means of which the pressure relief flap can be mobilized non-invasively during a post-operative healing phase or thereafter. The actuation area is preferably designed as a thermomechanically active area.Type: GrantFiled: February 27, 2018Date of Patent: February 9, 2021Assignee: ROWIAK GmbHInventor: Holger Lubatschowski

Patent number: 10799392Abstract: The invention relates to a controller for a surgical laser. According to the invention, the controller is adapted to control a laser in order to produce two or more three-dimensional compression zones, each comprising a plurality of lesions, inside a lens cortex of a crystalline lens of the eye using a laser pulse or multiple laser pulses, wherein the controller is adapted such that a laser can be calibrated with respect to a reference point within the lens, and each of the compression zones produced has a length in a radial direction, a depth in a direction parallel to the optical or visual axis and an average width in a direction parallel to a tangent of the lens cortex, wherein the sum of the average widths of all compression zones is 0.1 to 2 millimeter for every 1 diopter of desired gain in accommodation amplitude of the lens.Type: GrantFiled: December 23, 2011Date of Patent: October 13, 2020Assignee: ROWIAK GMBHInventors: Holger Lubatschowski, Omid Kermani, Georg Gerten, Uwe Oberheide

Patent number: 9603743Abstract: A device for processing material of a workpiece, the device including a pulsed processing laser, a focusing lens, a beam-deflection unit, a control unit and a confocal detector unit. The intensity of the laser radiation is variable. An imaging unit is provided to detect structures within the workpiece using electromagnetic radiation, wherein the electromagnetic radiation of the imaging unit is radiated via the beam-deflection unit and the focusing lens into the workpiece, and evaluating device is provided and compares the position of the focus of the laser radiation determined by the detector unit with the expected position of the focus in the image of the workpiece obtained by the imaging unit.Type: GrantFiled: December 22, 2011Date of Patent: March 28, 2017Assignee: ROWIAK GMBHInventors: Christian Rathjen, Holger Lubatschowski, Tammo Ripken

Patent number: 9162319Abstract: The invention relates to a method for removing material by means of a laser, wherein a sequence of laser pulses is generated and an area of material to be machined is irradiated with the sequence of laser pulses. Methods of this kind are used to cut a number of different materials. One problem with this method is that thermal or mechanical damage occurs in the surroundings of the area being machined and causes impairment of areas of material that are not being machined. The invention solves this problem by the pulse energy of a single pulse in the sequence of laser pulses being lower than the laser pulse energy required to produce material removal using an isolated laser pulse in the region irradiated with the single laser pulse of the sequence of laser pulses.Type: GrantFiled: August 21, 2006Date of Patent: October 20, 2015Assignee: ROWIAK GMBHInventors: Holger Lubatschowski, Tammo Ripken, Christian Rathjen
