Publication number: 20240168279Abstract: A contactless visualization system is for a surgical microscope for eye surgery. The system includes an ophthalmic loupe positionable in front of a patient's eye and for supplying a real and vertically and laterally inverted image of an eye fundus of the patient's eye in an intermediate image plane observable by the surgical microscope. The ophthalmic loupe includes a first and a second lens element. In a state positioned in front of the patient's eye, the first lens element is closer to the patient's eye than the second lens element. A wall extends from the first to the second lens element. The wall has a free end in a form of a mount in which the second lens element is held. The mount includes at least one cutout in which an edge of said second lens element is exposed in order to give a surgeon operating space.Type: ApplicationFiled: January 25, 2024Publication date: May 23, 2024Inventors: Jonathan Essig, Christian Beder

Patent number: 11974949Abstract: A laser-surgical apparatus includes a laser emitting laser light with a narrowband wavelength distribution, a digital image sensor or a plurality of digital image sensors that separately record(s) different color channels that represent mutually different spectral wavelength distributions with in each case one maximum corresponding to a specific spectral color and produce(s) separate pieces of image information for the individual color channels, and a graphics module for combining the separate pieces of image information into one color image. In addition, it includes a manipulation module for suppressing the laser light in the color image, which makes it possible to electronically manipulate the pieces of image information of the color channel the spectral wavelength distribution of which has the largest overlap with the narrowband wavelength distribution of the laser light before the separate pieces of image information are combined or during the combining of the separate pieces of image information.Type: GrantFiled: August 18, 2021Date of Patent: May 7, 2024Assignee: Carl Zeiss Meditec AGInventors: Frank Keib, Christian Beder, Peter Reimer
