  • Publication number: 20170049621
    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.

  • Patent number: 8307832
    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.

  • Patent number: 8201944
    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.

  • Patent number: 7950398
    Abstract: A method and device for modifying optical system properties by means of a continuously multifocal profile, wherein said profile comprises a component for increasing the optical system focal depth and is calculated according to a fourth-order Zernike polynom. The aim of said invention is to avoid the eye base refraction and, for this purpose, said focal depth increasing component is also calculated according to the second-order Zernike polynom.

  • Patent number: 7859684
    Abstract: A device for shaping objects by removal of material from the surface thereof with a pulsed laser beam and a deflecting device through which the laser bean is guided over the surface of the object. An optical device is provided for changing the distribution of the radiation intensity inside the laser beam cross section. After the passage of the laser beam through this optical device, the radiation intensity has a bell-shaped or Gaussian distribution, or a distribution similar to a bell-shaped or Gaussian distribution, in at least one cross-sectional direction through the laser beam.

  • 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.

  • Publication number: 20090227991
    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.
