Abstract: An apparatus for generating a correcting cut surface in the cornea including a laser unit, which can focus and move pulsed laser radiation; a first contact element; and a control unit, controlling the laser unit which has a standard setting which, when a standard curvature is imposed upon corneal surface by the first contact element, would lead to a standard cut surface.

The curvature, with respect to the reference surface of the correcting cut surface to be generated deviates from the known curvature of the standard cut surface. The apparatus includes a second contact element adapted to generate the correcting cut surface, which cornea imposes an actual curvature deviating from the standard curvature, thus generating a cut surface using the standard setting results in the correcting cut surface to be generated.

Abstract: The present invention makes it possible to make high-quality recordings of the anterior and/or posterior segments of the eye as an individual image or also as a sequence of images without increasing the radiation load on the eye to be examined. In the method according to the invention, at least one pre-flash is used in order to determine an optimal exposure time for the main flash based on the recording of the pre-flash which is reflected by the object to be recorded. Both the pre-flash and the main flash are controllable and the recordings of the pre-flash and main flash are recorded with the same sensor of the electronic camera and are evaluated electronically by a control unit, and the recording of the main flash and, as the case may be, of the pre-flash is analyzed and/or corrected and displayed to the user.
