Abstract: An arrangement including an air conveying device and a suction device guiding an air flow across a site for a duration of a process. The direction of air flowing towards the surface and a tangent to the surface at the ablation site intersect at an angle. A flow velocity of the air flow is controlled. A direction of air flowing away from the surface and the tangent at the site intersect. The flow velocity is selectable, within a specified range. A flow velocity is variable.

Abstract: A method for controlling a device for the treatment or refractive correction of the human eye using an electronic data processing system provides a simple overview of the influence of all of the parameters. To this end, once the operating parameters have been determined, a graphical simulation of the operating procedure is carried out in the form of a graphical visualization.

Abstract: A device for correcting visual defects of an eye comprises a coherent light source, a beam modification device for shaping and deflecting a beam of the coherent light source, and a wavefront analyzer device for analyzing a wavefront of an optical path in the eye.

Abstract: A method for changing a property of an eye uses a continuously multifocal profile that includes a component for increasing a focal depth. The method includes calculating the component for increasing the focal depth to be rotation-symmetrical. Alternatively, or in addition, the calculating is carried out so as to optimize an encircled energy criterion over an extended range of depth.

Abstract: A method for measuring the dynamic behavior of an optical system is aimed at rendering the dynamic behavior of the optical system objectively detectable. To this end, the optical system to be measured is stimulated by stimuli whereby causing it to react, and the reaction is detected by means of a wave front analysis.

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.

Abstract: A method and a corresponding system for removing material using laser radiation. The aim of the invention is to keep the laser beam cross-section free from contamination and to maintain constant ambient conditions at the site of removal during the removal process. Temperature and/or the humidity at the site of removal is maintained substantially constant a gas that is allowed to flow across the site of removal in a predetermined direction. The gas may have constant or varying temperatures, humidities and flow speeds during the removal process. The system may include a tubular channel through whose end a laser beam is incident on the surface of an object and removes material. A warm air current having a defined humidity is emitted from outlet openings of a flow channel that is linked with a conveyor via a connecting sleeve and is directed onto the site of removal.
