Patent ID: 8491575

Claim:
An apparatus for generating a correcting cut surface in the cornea of an eye so as to correct ametropia, said apparatus comprising: a laser unit, that focuses and moves pulsed laser radiation in the cornea to generate a cut surface; a first contact element with a standard curvature; a control unit, which controls the laser unit to generate such a cut surface and which has a standard setting which, when the standard curvature is imposed upon the anterior corneal surface by the first contact element, leads to a standard cut surface in the cornea, said standard cut surface having a known curvature with respect to a reference surface, wherein the curvature of the correcting cut surface to be generated, with respect to the reference surface, deviates from the known curvature of the standard cut surface and a second contact element adapted to generate the correcting cut surface; which second contact element, when in contact with the anterior corneal surface, imposes upon the corneal surface an imposed actual curvature deviating from the standard curvature, and thus has the effect that generating a cut surface using the standard setting of the control unit results in the correcting cut surface to be generated.
