Patent number: 10893799Abstract: A method for determining the topography of the cornea of an eye on the basis of an optical, contactless data capture. In the method for determining the topography of the cornea of an eye, which is based on a deflectometric method, the deflectometric measurements are carried out with the aid of a keratometric method by virtue of additional OCT-based scans being made at the keratometric measurement points, wherein the two measurement systems are registered to one another and both the keratometric and the OCT-based measurement values are recorded and used for mutual calibration to determine and output the topographic data. The proposed method serves to determine the topography of the cornea of an eye. It is helpful to ascertain the topography in order to be able to draw conclusions about possible pathological changes. Moreover, the exact measurement of the corneal topography is of great importance for correcting refractive errors.Type: GrantFiled: September 5, 2019Date of Patent: January 19, 2021Assignee: Carl Zeiss Meditec AGInventors: Manfred Dick, Ferid Bajramovic, Wei-Jun Chen, Tobias Bühren, Matthias Reich, Jörg Meissner, Martin Kühner

Patent number: 10517761Abstract: Systems and methods for localizing intraocular lens and/or existing refractive index patterns, to laser write-patterns, and to refractive index patterns in order to modify the refractive index by application of femtosecond laser pulses. OCT-based confocal detection and sectional image systems are provided for localization purposes, the systems being particularly suitable for the detection of phase patterns in addition to the localization of the IOL. With respect to laser write-patterns, the modification of existing refractive index patterns in the IOL is carried out by destroying existing structures or supplementing existing refractive index patterns.Type: GrantFiled: July 6, 2016Date of Patent: December 31, 2019Assignee: Carl Zeiss Meditec AGInventors: Gerhard Krampert, Johannes Kindt, Daniel Bublitz, Robert Pomraenke, Martin Kühner

Patent number: 9872617Abstract: A fundus camera with an OCT measurement module, in which, after the focusing objective, a mirror switches the light to be detected either to the OCT measurement module or an image detector. This design also renders it possible to carry out a method for improved focusing in order to improve the recording quality of the individual modalities. Furthermore, the multimodal measuring instrument distinguishes itself by an operating concept according to the invention. Such combination instruments are advantageous in that, as a result of the reduction from two instruments to one, less space is required than in the case of two separate instruments. Furthermore, reseating of the patient is avoided if recordings or measurements of different modalities should be made for one and the same patient, as a result of which the procedures in the medical practices and clinics can be influenced positively.Type: GrantFiled: December 12, 2016Date of Patent: January 23, 2018Assignee: Carl Zeiss Meditec AGInventors: Detlef Biernat, Markus Strehle, Axel Waldheim, Dietrich Martin, Martin Hacker, Eberhard Hagen, Martin Kühner, André Meyer

Patent number: 9364144Abstract: The eye is illuminated by a variable laser light source with a measurement range corresponding to the eye length, wherein the focus of the laser beam in the eye can be shifted laterally and/or axially by an adjustment mechanism, and the light fractions back-scattered from the sample are captured via an interferometer by a data acquisition unit and forwarded to a data processing unit. In the data processing unit, an OCT whole-eye scan is combined with at least one or several further overlapping tomographic part-eye or whole-eye scans. Reference information is used to register the first whole-eye scan with the further part-eye or whole-eye scans, and the combined whole-eye scan is evaluated and/or displayed on a user surface.Type: GrantFiled: August 18, 2011Date of Patent: June 14, 2016Assignee: Carl Zeiss Meditec AGInventors: Martin Hacker, Ferid Bajramovic, Rico Fuchs, Martin Kühner

Patent number: 9179839Abstract: A method for Determining at Least One Parameter for Diagnosis or Risk Assessment of a Disease, including AMD. The distribution of the macular pigment MP of an eye and at least one area A whose bordering line corresponds to a constant optical density MPD and/or concentration MPC of MP is determined by an analysis unit. The bordering line is subjected to a quantitative shape description. At least one parameter DP, suitable for diagnosing a disease and/or the risk of a disease is derived from the quantitative shape description of the bordering line of the areas A. The method is provided for diagnosis or risk assessment but may also be used in the context of treatment of macular pigment deficiency phenomena to select the required supplements. This method, based on the determination of the fractal dimension, is also suitable for diagnosing other diseases such as edemas, actinomycoses, atrophies or lesions.Type: GrantFiled: May 10, 2013Date of Patent: November 10, 2015Assignee: Carl Zeiss Meditec AGInventors: Thomas Mohr, Elke Machalett, Martin Hacker, Martin Kühner
