  • Publication number: 20110264081
    Abstract: A polarization beam splitter selectively decouples detection light onto a detector such that it has a polarization direction that differs from the emitted illumination light. This enables the detection of the light scattered back in the eye lens at a high level of accuracy, since stray light from reflections at optical components of the light path is suppressed. In the generating of photo disruptions or other incisions, the ray exposure of the retina may be reduced in that the incisions being furthest away from the laser are induced first such that laminar gas inclusions with an existence duration time of at least 5 seconds result. In this manner the laser radiation propagated in the direction of the retina in further incisions are scattered and partially reflected such that the influence impinging upon the retina is reduced.

  • Publication number: 20110224658
    Abstract: An ophthalmologic laser system and an operating method. The laser system includes a laser, a scanner unit, a focusing lens and a beam splitter that directs radiation that reaches the beam splitter from the direction of the area of examination through a confocal aperture orifice onto a detector. The invention also includes a control unit with which a cornea arranged in the examination area can be irradiated by the laser at illumination laser power and detection light can be registered by the detector. The cornea is scanned in three dimensions, in that the cornea is irradiated at multiple points and detection light is registered from there. Based on the detection light, a laser cut in the cornea is identified and the form and/or position of the laser cut calculated. The invention further relates to refractive laser surgery.

  • Patent number: 7926945
    Abstract: The present invention is directed to a device and a method for the observation, documentation and/or diagnosis of the fundus in which the diagnosis is carried out by evaluating the documented images of the fundus. The device according to the invention comprises an ophthalmological examination device, a multi-spectral sequential illumination module, an image recording module, a control and safety module, and an evaluating unit. The illumination module which is connected to the ophthalmologic examination device has at least two individual light sources and which can be regulated individually with respect to intensity and duration and which emit monochromatic light of different wavelengths. The light coming from the illumination module is imaged on the image recording module from the ophthalmologic examination device by the eye being examined. The control and safety module controls the chronological sequence, duration and intensity of the individual light sources and monitors the light stress.

  • Patent number: 7699467
    Abstract: This invention relates to a method and a device for the complete correction of sight defects in the human eye. Combinations of measuring, and processing methods are described which when applied as disclosed in the invention, make it possible to fully correct sight defects in the human eye. Measuring methods are used which can precisely scan the surface of the cornea and also register other imaging defects in the light path up to the retina. Computer-aided of said measuring results determined when combined with calculation of ideally corrected ocular lenses (for example after cataract operations) or ideally corrected surfaces of the cornea opens up the possibility of manufacturing a patient-specific lens and/or achieving ideal correction of the cornea using preferably a topography-supported spot-scanning-excimer laser system.
