1. A system for providing a course of refractive treatment for correcting a refractive error comprising:
- a computer system adapted to receive refractive eye data indicative of a refractive error of the eye, calculates at least a first treatment profile, which based upon the refractive eye data provides an overcorrection and calculates at least a second treatment profile suitable to correct said overcorrection, wherein the refractive error is S/C/A, wherein S denotes sphere, C denotes cylinder and A denotes astigmatism, the first treatment profile provides a correction of S+F1*S/C/A, and the second treatment profile provides a correction of −
FTS/0/0, wherein F1 is in the range of 0.05 to 0.3, wherein F1 is in the range of 0.05 to 0.15.

Abstract
The present invention relates to a system and a method for calculating a course of refractive treatment for correcting a refractive error of a patient'"'"'s eye. It is based on the concept to combine at least a first treatment which provides an overcorrection of the intended correction with at least a second treatment which corrects said overcorrection.
