Patent number: 11759105Abstract: An illumination system for producing a spatially distributed illumination pattern for measuring the cornea of an eye and, in particular, for determining the topography of the eye. In so doing, the system facilitates distance-independent measurements. The illumination system includes an illumination unit, an optical element for collimating the illumination light and a unit for producing a spatially distributed illumination pattern in the form of a fraxicon. In particular, the illumination unit includes a plurality of illumination modules which are arranged such that each illumination module illuminates part of the fraxicon, and consequently a full-area illumination is facilitated. The system for producing a spatially distributed illumination pattern serves to determine the topography of the cornea of an eye. Here, the system is designed as a compact module, and so it can be easily combined with other measurement systems, without interfering with the beam paths thereof.Type: GrantFiled: August 31, 2017Date of Patent: September 19, 2023Assignee: Carl Zeiss Meditec AGInventors: Beate Böhme, Rico Fuchs, Günter Rudolph, Michael Güntzschel, Jörg Meissner, Thomas Mohr, Daniel Bublitz

Publication number: 20220035116Abstract: A device and method of compensating for the temperature dependence of a facet lens used for determining the topography of an eye. According to the invention, temperature sensors are present for determining the temperature of the facet lens. In addition, the temperature dependence of the beam angles of the beam bundles is stored in a control and evaluation unit, which, in addition to the temperature of the facet lens transmitted by the temperature sensors, are taken into account by the control and evaluation unit when evaluating the recordings of the image recording unit. The device and method are described in the context of facet lenses that are used to determine the topography of an eye. However, in principle, they are usable wherever an existing temperature dependence, in particular of optical components, should be compensated for.Type: ApplicationFiled: November 20, 2019Publication date: February 3, 2022Applicant: Carl Zeiss Meditec AGInventors: Ferid BAJRAMOVIC, Rico FUCHS

Patent number: 10213103Abstract: A module for ophthalmological devices which enables ophthalmological devices to carry out keratometry and topography measurements of the eye. The proposed topography module is provided for ophthalmological devices with a distance-independent keratometer. The topography module, which is used to generate the luminous pattern, is arranged in a fixed or moveable manner in the beam path between the ophthalmological device and the eye. A control unit is provided to control the topography module for generating luminous patterns. The provided evaluation unit is also suitable to carry out keratometric as well as topographic evaluations of the reflection images of an eye, captured and transmitted by the detection unit. The invention enables ophthalmological devices, which are equipped with a distance-independent keratometer, to carry out additional topographical measurements on the eye.Type: GrantFiled: June 4, 2015Date of Patent: February 26, 2019Assignee: Carl Zeiss Meditec AGInventors: Matthias Reich, Rico Fuchs

Patent number: 9560958Abstract: Selection of an appropriate intraocular lens (IOL) and/or the applicable surgical parameters for optimizing the results of refractive procedures on the eye. Features of the IOL are crucial for the selection and/or adjustment of the optimal IOL, but so is the IOL selection method (and parameters) from a surgical perspective. For the method, corresponding output parameters are determined from predetermined, estimated, or measured input parameters and/or their mean values, wherein at least two input parameters are varied with one another and which have at least one input parameter as a distribution function. The resulting function is optimized by means of corresponding target values and the determined distribution function of one or more output parameters is used as a decision aid. The present solution is used for selecting an appropriate IOL and/or the applicable surgical parameters and is applicable in the field of eye surgery for implanting IOLs.Type: GrantFiled: September 12, 2014Date of Patent: February 7, 2017Assignee: Carl Zeiss Meditec AGInventors: Martin Hacker, Martin Kuehner, Rico Fuchs, Matthias Reich

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
