Patent number: 11950846Abstract: A device for determining biometric variables of the eye, as are incorporated in the calculation of intraocular lenses including a multi-point keratometer and an OCT arrangement. The keratometer measurement points are illuminated telecentrically and detected telecentrically and the OCT arrangement is designed as a laterally scanning swept-source system with a detection region detecting the whole eye over the whole axial length thereof. Illumination points are arranged in three rings concentrically around an instrument axis; and the three rings include a first ring, a second ring and a third ring and the illumination points on the first ring and the third ring are rotated in relation to the illumination points on the second ring such that each of the illumination points on the first ring is on a common radial with one of the illumination points on the third ring and each of the illumination points on the second ring is not on the common radial.Type: GrantFiled: June 29, 2022Date of Patent: April 9, 2024Assignee: Carl Zeiss Meditec AGInventors: Ralf Ebersbach, Martin Hacker, Gerard Antkowiak, Peter Klopfleisch, Ferid Bajramovic, Tobias Bühren, Matthias Reich

Publication number: 20220400947Abstract: A device for determining biometric variables of the eye, as are incorporated in the calculation of intraocular lenses including a multi-point keratometer and an OCT arrangement. The keratometer measurement points are illuminated telecentrically and detected telecentrically and the OCT arrangement is designed as a laterally scanning swept-source system with a detection region detecting the whole eye over the whole axial length thereof. The multi-point keratometer ensures that a sufficient number of keratometer points are available for measuring the corneal surface. By contrast, telecentricity ensures that the positioning inadequacies of the measuring instrument in relation to the eye to be measured do not lead to a local mismatch of the reflection points. The swept-source OCT scan detects the whole eye over the length thereof so that both anterior chamber structures and retina structures can be detected and a consistent whole eye image can be realized.Type: ApplicationFiled: June 29, 2022Publication date: December 22, 2022Inventors: Ralf EBERSBACH, Martin HACKER, Gerard ANTKOWIAK, Peter KLOPFLEISCH, Ferid BAJRAMOVIC, Tobias BÜHREN, Matthias REICH

Publication number: 20220313422Abstract: An intraocular lens system for implantation in an eye is provided. The intraocular lens system includes a ciliary body implant having a passive ciliary signal element, the ciliary body implant being implantable in the eye such that the ciliary signal element provides a ciliary signal in response to a movement of the ciliary muscle of the eye. The intraocular lens system also includes an intraocular lens having a sensor element for receiving the ciliary signal. The ciliary body implant and the intraocular lens are formed separately from each other and the intraocular system is configured to control a refractive effect of the intraocular lens that is dependent on the ciliary signal received from the sensor element.Type: ApplicationFiled: June 16, 2022Publication date: October 6, 2022Inventors: Jan Buchheister, Peter Klopfleisch, Lothar Müller, Ralph Semmler, Enrico Geißler

Publication number: 20220299732Abstract: An optical system includes at least one optical element which has an optically effective surface and which is designed for an operating wavelength of less than 30 nm. The optical system also includes a heating arrangement for heating this optical element and comprising a plurality of IR emitters for irradiating the optically effective surface with IR radiation. The IR emitters are activatable and deactivatable independently of each other to variably set different heating profiles in the optical element. The optical system further includes at least one beam shaping unit for shaping the beam of the IR radiation steered onto the optically effective surface by the IR emitters. The optical system also includes a multi-fiber head comprising a multi-fiber connector for connecting optical fibers. IR radiation from a respective one of the IR emitters is suppliable by way of each of these optical fibers.Type: ApplicationFiled: June 7, 2022Publication date: September 22, 2022Inventors: Andrea Berner, Susanne Beder, André Dirauf, Hans-Michael Stiepan, Peter Klopfleisch

Patent number: 11129525Abstract: The invention relates to a method for examining an eye of a patient by the patient themselves by means of an ophthalmological apparatus, said apparatus having front optics and an apparatus pupil. According to said method, the patient positions the ophthalmological apparatus relative to the eye, a measure of the deviation of the pupil of the eye from the apparatus pupil is determined, and a pupil correction signal is produced depending on the measure of the deviation, said pupil correction signal specifying a direction and/or a degree of the deviation and being output to the patient. The patient can use the pupil correction signal for repositioning in relation to the ophthalmological apparatus with a smaller deviation.Type: GrantFiled: November 7, 2017Date of Patent: September 28, 2021Assignee: Carl Zeiss Meditec AGInventors: Peter Westphal, Tobias Schmitt-Manderbach, Daniel Bublitz, Peter Klopfleisch
