Abstract: The invention relates to a method for controlling a device for the treatment or refractive correction of the human eye by means of an electronic computer. The aim of the invention is to create a method for controlling a device for treating the human eye, which 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: There is now provided a method for determining vision defects and for collecting data for correcting vision defects of the eye. The method comprises projecting an image into the eye of the patient with an adaptive optical system having adaptive optical elements. The optical characteristics of the optical elements can be individually changed by an electrical signal. The presence of distortions of the image as perceived by the patient is determined by interaction of the patient with the examiner. By way of an electronic control system the optical characteristics of the adaptive optical elements are changed through outputting of an electrical signal to obtain a modified image with minimized distortions in the eye of the patient. The optical characteristics of the adaptive optical elements, as modified, are determined and vision correcting data for the eye being examined are computed from the optical characteristics of the adaptive optical elements, as modified.

Abstract: The invention relates to a method for measuring the dynamic behavior of an optical system. The aim of the invention is to render the dynamic behavior of an 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: The invention relates to a method for identifying the site of an operation (1) during an operation, in particular using a laser system (20), with the help of unique data (10) about the operation site (1). A first copy (11) of the unique data (10) is stored in a laser system (20), the unique data (10) being located in the vicinity of the operation site (1) and/or directly at said operation site (1). Before the start of the operation, the first copy (11) and the unique data (10) are compared to verify if they are identical and the result of said verification is forwarded to the laser system (20). The invention also relates to a device that carries out said method.

Abstract: The invention relates to a method and to a device for completely correcting visual defects of the human eye. The invention mentions combinations of measuring and treatment methods that allow the complete correction of defects of the human eye if applied according to the invention. Measuring methods are used that precisely detect the surface of the cornea and that also register the aberrations that occur in the beam path up to the retina. The computer-assisted evaluation of these measurement results combined with the calculation of optimally corrected lenses (for example after a cataract operation) or of optimally correcting cornea surfaces makes it possible to produce a patient-specific lens and/or to shape the retina so that it optimally corrects the aberration. To this end, the invention preferably uses a spot scanning excimer laser system and makes use of the topography of the eye.

Abstract: A process and device for shaping surfaces by laser machining and which are used for photorefractive keratectomy and shaping contact lenses. The shaping is performed in stages so that after any interruption in the process, a complete partial correction of the entire surface is obtained. A computing unit receives data from input units and directs data to a block generator which associates laser machining coordinates to enable the removal of individual surface layers. A sequence generator gathers the data generated by the block generator into blocks which correspond to an individual ablation areas, and orders the blocks into sequences. A block sequence transmitted by the sequence generator acts upon a laser beam deflector and beam shaping unit such that the complete partial correction of the surface is obtained for each block sequence. A central processor coordinates control of the laser, the beam shaping unit and the laser beam deflector.
