Abstract
An apparatus and method are disclosed for providing control data for a laser of a treatment apparatus for the correction of a cornea. The method includes determining a look-up table for preset corneal parameters by a corneal deformation model, wherein the cornea can be modeled in deformed and non-deformed states by the corneal deformation model. A value of at least one preset corneal parameter in the non-deformed state of the cornea is varied and an effect of this variation on values of the corneal parameters in the deformed state of the cornea is ascertained for determining the look-up table. The method further includes ascertaining a corneal value to be achieved from predetermined examination data, determining by the look-up table a deformation-corrected corneal value to be achieved for compensating for the deformation of the cornea, and providing control data, which uses the deformation-corrected corneal value for correcting the cornea.
