摘要： A device and method for the pre-display of a spot pattern to be applied for a laser treatment of the eye. The spot patterns to be applied are displayed to the operator in advance with the aid of a target beam. The device for the pre-display of a spot pattern to be applied for a laser treatment of the eye includes a laser system and a scanning system for generating a target beam. Here, the laser system and the scanning system for generating the target beam are formed to generate one or more lines which overlie all the spots of the spot pattern of a planned laser treatment. The device and method are suitable for laser treatment of the retina, the trabecular meshwork as well as other regions. Here, it is irrelevant whether what the laser treatment to be applied is.

摘要： A method for determining the topography of the cornea of an eye on the basis of an optical, contactless data capture. In the method for determining the topography of the cornea of an eye, which is based on a deflectometric method, the deflectometric measurements are carried out with the aid of a keratometric method by virtue of additional OCT-based scans being made at the keratometric measurement points, wherein the two measurement systems are registered to one another and both the keratometric and the OCT-based measurement values are recorded and used for mutual calibration to determine and output the topographic data. The proposed method serves to determine the topography of the cornea of an eye. It is helpful to ascertain the topography in order to be able to draw conclusions about possible pathological changes. Moreover, the exact measurement of the corneal topography is of great importance for correcting refractive errors.

摘要： An arrangement for OCT-based laser treatment of vitreous floaters. The arrangement for OCT-based laser vitreolysis includes an OCT system, a laser system having a deflection unit, optical elements that couple the OCT system and the laser system, a display unit and a central control and operating unit. The OCT system is configured to localize the floaters, the laser system is configured to destroy the floaters by application of laser pulses and the central control and operating unit is configured to determine apart from the coordinates of the localized floaters also their distance to structures of the eye, to derive exclusion criteria for the treatment, to align the deflection unit of the laser system to these coordinates and to focus and activate the laser system. The present invention relates to an arrangement for the gentle, low risk and painless laser treatment of vitreous floaters, which enables partially or fully automated therapy.

摘要： 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 μs are provided for selective therapies and pulse lengths ranging from 50 μs 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.

摘要： The invention relates to a device for measuring an optical penetration that is triggered in a tissue underneath the tissue surface by means of therapeutic laser radiation which a laser-surgical device concentrates in a treatment focus located in said tissue. The inventive device is provided with a detection beam path comprising a lens system which couples radiation emanating from the tissue underneath the tissue surface into the detection beam path. A detector device generating a detection signal which indicates the spatial dimension and/or position of the optical penetration in the tissue is arranged downstream of the detection beam path.

摘要： A method for collecting biometric measurement data of an eye on the basis of different measurement modalities, allowing for physiologically correct, representative, and robust biometric measurement data. In the method, the measurement data for individual measurement variables and the dynamic behavior of the eye are recorded continuously at the highest possible repetition rate over the measurement time. The individual phases of the dynamics of the eye which define the limits of the phase for stable vision are analyzed on the basis of the measurement values, and only the measurement data for the individual measurement variables are output which have been detected during the phase for stable vision. Although the proposed method is provided for collecting biometric measurement data in preparation for a cataract operation, the method can also be applied to other areas of ophthalmology to generate error-free measurement data or recordings of the eye.

摘要： 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.
