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.

Method for controlling a device for treating the human eye

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.

Method and device for performing online aberrometry in refractive eye correction

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.

Method and device for increasing an optical system focal depth

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.

Method, device and arrangement for measuring the dynamic behavior of an optical system

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.

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.

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.

A device for the subjective determination of aberrations of higher orders Xi in an optical system, in particular in an eye includes at least one observation channel into which defined plates can be introduced, the individual plates having optically active structures which correspond to a defined Zernike polynomial and to a defined amplitude, at least one order Xi of the Zernike polynomial being greater than two.

Method and device for the subjective determination of aberrations of higher order

The present invention relates to a method and a device for treating opacities and/or hardenings of an unopened eye. It is a specific advantage of the solution according to the invention that the treamtment of the inner region of the eye is possible without the need to introduce a surgical instrument into the eye.

Method and device for treating opaqueness and/or hardening of a closed eye

A device for the subjective determination of aberrations of higher orders Xi in an optical system, in particular in an eye includes at least one observation channel into which defined plates can be introduced, the individual plates having optically active structures which correspond to a defined Zernike polynomial and to a defined amplitude, at least one order Xi of the Zemike polynomial being greater than two.
