Patent number: 9919081Abstract: Embodiments relate to an ophthalmology microscopy-system and a method of operating an ophthalmology microscopy-system which allow for an at least partial or full removal of liquids and gels used in ophthalmology for application in an eye of a patient in an particularly efficient way. Further embodiments relate to a product such as a liquid or a gel usable for an application in an eye of a patient, wherein the product has a high transmittance and, nevertheless, may be made visible particularly well.Type: GrantFiled: October 27, 2014Date of Patent: March 20, 2018Assignee: CARL ZEISS MEDITEC AGInventors: Anja Seiwert, Christoph Hauger, Roland Guckler, Claude Moissonnier

Patent number: 9538914Abstract: An ophthalmology microscopy system for observing fluorescence comprises an imaging system and an illumination system. The imaging system provides at least one optical imaging path producing a magnified multi-dimensional image of an object disposable in a focal plane of the imaging system, and comprises at least one optical observation filter. The illumination system provides an illumination beam path intersecting the focal plane of the imaging system at a variable angle of less than 90°. The microscopy system comprises first and second operating states. In the first operating state, radiation passing through the illumination beam path has at least in a section along the illumination beam path a spectrum free of a pass band of the observation filter. In the second operating state, radiation passing through the illumination beam path has a spectrum having a bandwidth of at least 200 nm in a range from 380 nm to 780 nm.Type: GrantFiled: June 9, 2014Date of Patent: January 10, 2017Assignee: CARL ZEISS MEDITEC AGInventors: Christoph Hauger, Holger Matz, Anja Seiwert

Patent number: 9462944Abstract: A surgical microscopy system comprises microscopy optics for generating an image of an eye under surgery. A pattern generator generates a pattern to be superimposed with the image. An eye-tracker is provided for tracking a position of the superimposed pattern with respect to the image in case of a movement of the eye. The superimposed pattern comprises pattern elements that are equally distributed on first and second circles of different sizes, in order to give assistance when placing a suture during a corneal transplant. The superimposed pattern may also provide an assistance for orientating a toric intra-ocular lens.Type: GrantFiled: March 4, 2011Date of Patent: October 11, 2016Assignee: CARL ZEISS MEDITEC AGInventors: Gerhard Moeller, Anja Seiwert, Michel Perez, Peter Amend

Patent number: 8708488Abstract: A method for carrying out eye surgery comprises a comparison of images recorded before surgery with images recorded during surgery in order to generate a marker which represents a target orientation of an intraocular lens or a difference between a current orientation and the target orientation of the intraocular lens. An eye surgery system respectively comprises an imaging system which is used during a surgery and has a camera, and a diagnostic system which is used before surgery and which also has a camera. The imaging system used during surgery comprises an image processing device in order to perform a computation based on the recorded images, and in order to determine a respective orientation value, from which a representation of a marker representing the target orientation of the intraocular lens is obtained.Type: GrantFiled: July 24, 2009Date of Patent: April 29, 2014Assignee: Carl Zeiss Meditec AGInventors: Martin Kraus, Christoph Kuebler, Delbert Peter Andrews, Mark Lansu, Thomas Schuhrke, Anja Seiwert
