Patent number: 11951042Abstract: A device and method for the pre-display of a spot pattern to be applied for a laser treatment of the eye. The spot patterns to be applied are displayed to the operator in advance with the aid of a target beam. The device for the pre-display of a spot pattern to be applied for a laser treatment of the eye includes a laser system and a scanning system for generating a target beam. Here, the laser system and the scanning system for generating the target beam are formed to generate one or more lines which overlie all the spots of the spot pattern of a planned laser treatment. The device and method are suitable for laser treatment of the retina, the trabecular meshwork as well as other regions. Here, it is irrelevant whether what the laser treatment to be applied is.Type: GrantFiled: April 4, 2019Date of Patent: April 9, 2024Assignee: Carl Zeiss Meditec AGInventors: Manfred Dick, Gerald Kunath-Fandrei, René Denner, Thomas Wurlitzer

Patent number: 11766357Abstract: A device for superimposing parameters and/or image data in the stereoscopic observation path of ophthalmological devices relates to an apparatus for reflecting relevant parameters and/or image data into the stereoscopic observation beam path of ophthalmic devices, for example for therapeutic laser treatments of an eye. The device includes an additional micro-display, which is connected to the control unit, and a beam deflection element for reflecting the parameters and/or image data shown on the micro-display into the stereoscopic observation beam path, which are for example arranged in the parallel beam path. Even though the apparatus is intended for ophthalmic devices for therapeutic laser treatment in the eye, it can also be used, in principle, for ophthalmic devices for examination, diagnosis and surgical interventions.Type: GrantFiled: September 28, 2018Date of Patent: September 26, 2023Assignee: Carl Zeiss Meditec AGInventors: Manfred Dick, Gerald Kunath-Fandrei, René Denner, Thomas Wurlitzer, Rolf Teuscher

Patent number: 11660231Abstract: A method for a minimally invasive, cell-selective laser therapy on the eye. The method, based on a short-pulse laser system, allows for different selective types of therapy on the eye. The method is based on a frequency-doubled, continuously working solid-state laser including a pump source and a control unit. The control unit regulates the pump source such that the solid-state laser emits individual pulses with pulse lengths ranging from 50 ns to continuous, wherein pulse lengths ranging from 50 ns to 50 ?s are provided for selective therapies and pulse lengths ranging from 50 ?s to continuous are provided for coagulative or stimulating therapies, in particular in the range from 1 ms to 500 ms. The proposed method enables a selective treatment of melanin-containing cells in the different areas of the eye via the targeted control of the pump source.Type: GrantFiled: March 16, 2021Date of Patent: May 30, 2023Assignee: Carl Zeiss Meditec AGInventors: Manfred Dick, Gerald Kunath-Fandrei, René Denner, Thomas Wurlitzer

Patent number: 8567948Abstract: A device for examining the eye fundus and photoreceptors includes an illumination beam path having optical beam forming and/or guiding components, at least one illumination unit for providing a continuous illumination and a flash illumination, and an observation and imaging beam path having optical beam forming and/or guiding components and a device for varying the magnification, including a beam splitter for splitting the observation and imaging beam path. A rotatable diffraction grating is disposed in a plane in the observation and imaging beam path that is conjugate to the object plane and the movement of the grating is synchronized with the illumination unit that serves as the flash illumination so that an image recording sensor records a rapid sequence of images of the eye fundus at different positions of the grating and said sequence is forwarded to an existing evaluation unit.Type: GrantFiled: September 16, 2008Date of Patent: October 29, 2013Assignee: Carl Zeiss Meditec AGInventor: Gerald Kunath-Fandrei

Publication number: 20130085481Abstract: A device intended to permit photocoagulation or phototherapy at low cost and in a shorter time. For this purpose, an ophthalmology appliance includes a radiation source having several discrete individual emitters. The therapy beam path leading from the radiation source to the treatment area projects an image of at least respective portions of different individual emitters simultaneously onto surfaces spaced apart from each other in the treatment area. This permits simultaneous generation of several coagulation foci and dispenses with the need for electromechanical beam-deflecting units, which permits a shorter treatment time.Type: ApplicationFiled: May 28, 2011Publication date: April 4, 2013Applicant: CARL ZEISS MEDITEC AGInventors: Manfred Dick, René Denner, Gerald Kunath-Fandrei
