Patent number: 11278451Abstract: A computer program product for controlling a laser-assisted eye treatment, configured to encode a system controller with a routine for planning the eye treatment, invention further relates to a laser-assisted eye treatment system including a laser treatment unit and a system controller, to a method for generating control data for a laser-assisted eye treatment system, to a planning method for a laser-assisted eye treatment and to an eye treatment method using a laser beam for treating a patient's eye. The invention provides systems and methods for a fast laser-assisted eye treatment of a patient's eye which improve the security and minimize the risk of a non-optimal eye treatment and enable sale eye treatment planning and a shortening of the critical phase of the eye treatment. Encoding a system controller by a routine for planning the eye treatment is strictly based on an anatomy of a patient's eye.Type: GrantFiled: September 15, 2016Date of Patent: March 22, 2022Assignee: Carl Zeiss Meditec AGInventors: Delbert Peter Andrews, Michael Stefan Rill, Stefan Gräber, Julia Werth, Rupert Menapace

Patent number: 9883796Abstract: An ophthalmologic system comprising and eye tracker and an OCT system. A method of operating the ophthalmologic system comprises: providing data representing a placement of a first B-scan performed on an eye relative to the eye; performing a measurement on the eye using the eye tracker; determining a placement of the eye relative to the ophthalmologic system based on the measurement using the eye tracker; placing the eye relative to a reference placement of the OCT system based on the provided data and the determined placement; performing A-scans on the eye at at least three A-scan positions; determining a placement of a second B-scan relative to the OCT system based on at least one of the at least three A-scans and the provided data such that the second B-scan and the first B-scan have a substantially same placement relative to the eye; and generating a representation of the second B-scan.Type: GrantFiled: October 2, 2015Date of Patent: February 6, 2018Assignee: CARL ZEISS MEDITEC AGInventors: Günter Meckes, Konstantinos Filippatos, Thomas Schuhrke, Christoph Hauger, Abouzar Eslami, Stefan Gräber, Christine Kochwagner, Carolin Schiele, Christopher Käsbach

Patent number: 8662667Abstract: A method determines the position and/or radius of the limbus and/or the position and/or radius of the pupil of a patient eye. In the method, an image of the patient eye is obtained and a plurality of different ring-shaped comparison objects having respective radii and respective centers are provided. The image is correlated with the plurality of comparison objects to yield a local best match between the image and the comparison objects when there is a coincidence of one of the ring-shaped comparison objects and a ring-shaped jump in brightness in the image having the same radius and the same center. The comparison objects having a local best match with the image are determined. Thereafter, the position of the center of the comparison object having a local best match with the image is selected as the position of the center of the limbus and/or the position of the center of the pupil.Type: GrantFiled: June 21, 2010Date of Patent: March 4, 2014Assignee: Carl Zeiss Meditec AGInventors: Thomas Schuhrke, Günter Meckes, Stefan Gräber, Keith Thornton

Patent number: 8308298Abstract: The invention relates to an eye surgery microscopy system (1) having an imaging optic (14, 11) for the generation of the image of an object plane (15) and having an electronic image sensor (22), which detects the image of the object plane (15) and is connected to a computer unit (5) for the computation of the position of the center of a circular structure (44) of a patient eye (16). The computer unit (5) is designed for the computation of the position of a patient eye (16) outside of the center (52) of the circular structure (44) and provided with at least one marking (46, 48). The computer unit (5) determines the position of the at least one marking (46, 48) with reference to the computed center (52) by means of image processing via correlation with a comparison information, and an angular position of the at least one marking (46, 48) with reference to the computed center (52) by means of image processing.Type: GrantFiled: June 24, 2010Date of Patent: November 13, 2012Assignee: Carl Zeiss Meditec AGInventors: Thomas Schuhrke, Günter Meckes, Stefan Gräber, Keith Thornton

Patent number: 6106421Abstract: An uncoupled belt pulley having a hub ring and a flyring, the hub ring and flyring being associated together, concentrically adjacent to one another and radially spaced apart, with a first spring body that is disposed in a gap formed by the interposed space. A belt pulley is connected to the hub ring in a rotationally elastic manner via a second spring body. The belt pulley and the second spring body are axially adjacent to one another.Type: GrantFiled: November 10, 1998Date of Patent: August 22, 2000Assignee: Firma Carl FreudenbergInventors: Stefan Graber, Peter Barsch
