Publication number: 20220409429Abstract: An ophthalmological laser therapy system including an apparatus main body and a laser device which is arranged in the apparatus main body and in a laser arm. The laser arm is arranged on the apparatus main body and includes a lighting arrangement. The invention furthermore relates to a planning device and a planning method for planning a laser therapy on an ophthalmological laser therapy system. It seeks to provide an ophthalmological laser therapy system and a method, by which an optimal psychological (calming) effect can be facilitated for every patient. This calming effect is achieved by an ophthalmological laser therapy system whose laser arm has a lighting arrangement the color of which is variable on an individual basis, and by a corresponding planning device and a corresponding planning method.Type: ApplicationFiled: September 8, 2020Publication date: December 29, 2022Applicant: Carl Zeiss Meditec AGInventors: Frank BRÜCKNER, Burkhard WAGNER, Gregor STOBRAWA

Patent number: 9599971Abstract: A method operates an onboard power supply system in a motor vehicle. The onboard power supply system has a master controller and a slave controller, in which the master controller communicates with the slave controller via a subsidiary bus system and a further onboard power supply system component via a main bus system. Present requests are received in the slave controller and in response to the present requests, performing one of: putting the slave controller into an operating mode and switching the master controller to a transmission mode, in which the master controller coordinates communication between the slave controller and the onboard power supply system component; or putting the slave controller into a sleep mode and switching the master controller to an undertaking mode, in which the master controller responds to queries from the onboard power supply system component to the slave controller.Type: GrantFiled: June 10, 2013Date of Patent: March 21, 2017Assignee: Brose Fahrzeugteile GmbH & Co.

Patent number: 9462938Abstract: For the pre-operative calculation of the power of an intraocular lens, three input parameters are needed: the axial length of the eye (AL), the refractive power of the cornea, and the distance between the front of the cornea and the back focal plane of the intraocular lens, the so-called effective lens position (ELP). The invention shows a novel approach to the determination of the ELP.Type: GrantFiled: August 25, 2015Date of Patent: October 11, 2016Assignee: Carl Zeiss Meditec AGInventors: Rudolf Murai Von Bünau, Burkhard Wagner, Scott A.

Patent number: 9351634Abstract: A method for calculating the values of an intraocular lens to be implanted, wherein the results of numerous cataract operations are taken into account in the calculation for intraocular lenses to be implanted in the future. At least the corneal topography, the length of the eye and the depth of the anterior chamber are determined pre-operatively, the values of the IOL to be implanted are calculated by means of ray-tracing, and at least the corneal topography, the length of the eye, the depth of the anterior chamber and the objective, wavefront-based residual refraction are determined post-operatively. The measurement values determined pre-operatively and post-operatively are used to optimize the surgically-induced astigmatism and the post-operative anatomical lens position for calculating the values of IOLs to be implanted in the future.Type: GrantFiled: September 14, 2012Date of Patent: May 31, 2016Assignee: Carl Zeiss Meditec AGInventors: Tobias Bühren, Michael Trost, Burkhard Wagner

Patent number: 9084564Abstract: A system for determining the surface shape of the cornea of an eye by analyzing the reflection of a spatially distributed ring pattern. The system includes an element for generating a ring pattern, an illuminating unit, an image capturing unit, and a control and analyzing unit. The element for generating rings is a fresneled axicon with annular structures of different radii. Furthermore, an optical element for illuminating the entire surface of the fresneled axicon with plane waves and an optical element for separating the illuminating and detecting beam path are arranged between the illuminating unit and the fresneled axicon. Furthermore, the image capturing unit consisting of an imaging system and an image sensor is designed for a telecentric distance-independent image detection.Type: GrantFiled: May 22, 2012Date of Patent: July 21, 2015Assignee: Carl Zeiss Meditec AGInventors: Daniel Bublitz, Günter Rudolph, Martin Hacker, Tobias Bühren, Roland Bergner, Burkhard Wagner, Rico Fuchs

Patent number: 8801184Abstract: A system for the improved imaging of eye structures based on optical coherence tomography. The system includes an interferometric measuring arrangement, which has an optical element arranged in the measurement arm or reference arm for influencing the polarization state of the light before the light is interferometrically superimposed, a scanning unit arranged in the measurement arm for implementing OCT scans, a detector for recording the produced interference pattern, and an evaluating and documenting unit. At least two different polarization states of the light are produced. The interference patterns produced in the interferometric measuring arrangement are recorded and forwarded to the evaluating and documenting unit which reconstructs OCT scans from the transmitted interference patterns, combines the OCT scans, and presents and/or stores the resulting OCT signals. The system can be used for pachymetry in addition to the pre- and post-operative imaging for analysis and measurement.Type: GrantFiled: April 23, 2011Date of Patent: August 12, 2014Assignee: Carl Zeiss Meditec AGInventors: Martin Hacker, Rudolf Murai von Bünau, Burkhard Wagner
