Apparatus for generating a correcting cut surface in the cornea of ​​an eye to correct refractive errors and contact element for such a device.

摘要

A device is provided for generating a correction incision surface in the cornea of an eye for ametropia correction, comprising a laser unit (2) which can focus and move pulsed laser radiation (6) for cutting surface formation into the cornea (11), a first contact element and a Control unit (3), which controls the laser unit (2) for cutting surface production and has a default setting, which leads to a reference surface with a known curvature to a reference surface in a default curvature of the cornea front surface in the cornea (11) impressed by the first contact element the curvature profile of the correction cut surface to be generated differs relative to the reference surface from the known curvature profile of the producible standard cut surface and the device has a second contact element (4) adapted to produce the correction cut surface, which contacts the horn horn autvorderfläche this imposes a deviate from the standard curvature of actual curvature and thereby causes a performed with the default setting Schnittflächenerzeugung leads to be generated correction interface.
