Abstract
The invention relates to an apparatus and a method for providing data for vision correction utilizing a volumetric ablation and an intrastromal manipulation. The provided data may be used by a laser ablating the surface of the cornea in combination with a laser which operates intrastromal to optimize a corneal re-shaping procedure. One aspects of the invention relates to the minimization of the amount of corneal tissue to be removed.
