  • Patent number: 11766357
    Abstract: A device for superimposing parameters and/or image data in the stereoscopic observation path of ophthalmological devices relates to an apparatus for reflecting relevant parameters and/or image data into the stereoscopic observation beam path of ophthalmic devices, for example for therapeutic laser treatments of an eye. The device includes an additional micro-display, which is connected to the control unit, and a beam deflection element for reflecting the parameters and/or image data shown on the micro-display into the stereoscopic observation beam path, which are for example arranged in the parallel beam path. Even though the apparatus is intended for ophthalmic devices for therapeutic laser treatment in the eye, it can also be used, in principle, for ophthalmic devices for examination, diagnosis and surgical interventions.

  • Patent number: 11766171
    Abstract: A method for capturing biometric measurement data of a patient's eye, in which the fixation is monitored during the entire biometric measurement. Information in respect of the fixation is extracted, depending on the different recording modes, from already available or additionally captured recordings and/or data. Central retinal OCT scans with absolute fixation information and frontal images with relative fixation information with or without at least partial diffuse lighting are used. On the basis of this extracted fixation information, the subsequent evaluation only uses the captured biometric measurement data captured just before, at the same time as or just after frontal images with the correct fixation. The method can also be applied to different measurement tasks, in which use is made of different measurement modes and in which the alignment of the measurement object is important for the measurement results.

  • Patent number: 11766307
    Abstract: A method and device are for generating and displaying a map of a brain operating field, brain tissue areas associated with a stimulated brain function being marked in the map. In the method, during a measurement cycle a stimulation of a brain function is effected and a stimulation image of the brain operating field with the stimulated brain function is recorded, a reference image without the stimulated brain function is recorded, the stimulation image and the reference image are used to generate the map, and the map is displayed on a display. A plurality of cycles are performed. A new map is generated after each cycle following the first cycle. In order to generate the new map, the stimulation and reference images of one or more preceding cycles are used besides the images recorded in the cycle just carried out. At least the new map is displayed after each cycle.

  • Patent number: 11759105
    Abstract: 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.

  • Patent number: 11744466
    Abstract: An apparatus is for localizing brain tissue regions connected with a brain function in a brain operating field. The apparatus includes a stimulation apparatus and a localization unit with a camera. The stimulation apparatus is configured to carry out a number of stimulation cycles. Each cycle includes a stimulation phase during which the brain function is stimulated and a rest phase during which there is no stimulation of the brain function. The localization unit records at least one stimulation image with the stimulated brain function and at least one reference image without the stimulated brain function during each stimulation cycle and uses the recorded stimulation and reference images to localize the brain tissue regions connected with the stimulated brain function. The stimulation apparatus is configured to output a feedback signal to the localization unit with at least the start of a stimulation cycle being evident from the feedback signal.

  • Patent number: 11660231
    Abstract: A method for a minimally invasive, cell-selective laser therapy on the eye. The method, based on a short-pulse laser system, allows for different selective types of therapy on the eye. The method is based on a frequency-doubled, continuously working solid-state laser including a pump source and a control unit. The control unit regulates the pump source such that the solid-state laser emits individual pulses with pulse lengths ranging from 50 ns to continuous, wherein pulse lengths ranging from 50 ns to 50 ?s are provided for selective therapies and pulse lengths ranging from 50 ?s to continuous are provided for coagulative or stimulating therapies, in particular in the range from 1 ms to 500 ms. The proposed method enables a selective treatment of melanin-containing cells in the different areas of the eye via the targeted control of the pump source.
