    摘要: An ophthalmic laser ablation system is described with various optional features, some especially suitable for non-penetrating filtration on an eye. In one example, focusing of an ablation laser uses a movable lens coupled to a pair of converging light sources, which converge at the focal distance of the lens. In another example, laser ablation settings are selected for optimal ablation and minimal amount of thermal damage of a layer of percolating scleral tissue.

    摘要: Die vorliegende Erfindung betrifft ein Strahlformungselement für optische Strahlung, insbesondere für UV-Laserstrahlung, sowie ein Verfahren zur Herstellung. Das Strahlformungselement weist ein Trägersubstrat (1) mit einer strukturierten Dünnschicht-Metallisierung zur Strahlformung der optischen Strahlung auf, wobei sich die Dünnschicht-Metallisierung aus zumindest zwei metallischen Schichten (2, 3) zusammensetzt, die beim Auftreffen der optischen Strahlung (4) ab einer bestimmten Intensität und/oder Bestrahlungsdauer der optischen Strahlung (4) unter permanenter Farbänderung miteinander reagieren. Bei dieser Ausgestaltung des Strahlformungselementes wird bei der Benutzung eine optisch sichtbare Gebrauchsspur hinterlassen, so dass eine versehentliche Mehrfachnutzung ausgeschlossen werden kann.

    摘要: The description relates to a device for shaping the cornea with a laser, the beam of which has a circular mode distribution and a beam shaping and guiding device which directs the laser beam to the cornea. In the invention, to make the energy density uniform over the radiation cross-section, the beam shaping device has a focussing lens to focus the broadened laser beam, a diffracting component which is arranged at a short distance from the focal plane of the focussing lens and the maximum diffractions of which interfere with the minima of the mode distribution, and an image field diaphragm arranged at a point optically conjugated with the cornea.

    摘要: A phantom cornea (5) for calibrating surgical lasers is formed by superimposition of thin-films (6-9) of alternating colors. After ablation by a laser beam, the resulting spherical cavity appears as a pattern (12) of nested circles whose concentricity and spacing reflect the alignment and intensity of the laser beam. These patterns can be visually or instrumentally analyzed to determine the proper setting of the laser. A monolayer or multi-layer thin film is used to determine, not only the ablative power of a laser beam, but also the variation of the ablative power over the full breadth of the beam by observing the area (29-33) impinged by the beam between successive laser pulses. The calibration cornea can be planar (5), or arcuate (18) to mimic the natural cornea. The calibration cornea may be mounted in a phantom eyeball (24) including a removable iris (26) of small diameter which constitutes a convenient target for the alignment of the laser beam.

    摘要: The description relates to a device for photoablation, especially for photorefractive surgery, with a pulsed laser system (1), the laser beam of which is directed on a region to be ablated (5). The invention is characterized in that there is a beam splitter (4) in the beam path of the laser system (1) in front of the region to be ablated and that in the path of the partial beam (6b) emitted from the beam splitter (4) which is not directed on the region to be ablated (5) there is a film-like material (7), the ablation properties of which are comparable to the material of the region to be ablated (5), and behind the film-like material (7) there is at least one photosensor (9), the output signal from which is applied to a control unit (10) which stops further laser pulses when the photosensor (9) is irradiated.

    摘要: Embodiments of the present invention generally describe systems, devices, and methods for directly measuring pulse profiles during pulse delivery. In some embodiment, the pulse profiles may be measured while the pulse is delivered to ablate a material. Embodiments, may calculate ablation spot parameters based on the pulse profiles and may refine one or more subsequent laser pulses based on deviations from the calculated ablation spot parameters from desired ablation spot parameters. In some embodiments, a fluence profiler is provided. The fluence profiler may measure a pulse profile of a laser pulse from a portion of the laser pulse. The fluence profiler may utilize a UV radiation energy sensor device and a camera-based imager. The measurements from the UV radiation energy sensor device and the camera-based imager may be combined and scaled to provide a measured pulse profile that corresponds to the delivered pulse.
