Abstract
A device for producing control data for a laser device for the surgical correction of defective vision. The device produces the control data such that the laser emits the laser radiation such that a volume in the cornea is isolated. The device calculates a radius of curvature R* to determine the control data, the cornea reduced by the volume having the radius of curvature R* and the radius of curvature being site-specific and satisfying the following equation: R*(r,φ)=1/((1/R(r,φ))+B(r,φ)/(n−1))+F, wherein R(r,φ) is the local radius of curvature of the cornea before the volume is removed, nis the refractive index of the material of the cornea, F is a coefficient, and B(r,φ) is the local change in refractive force required for the desired correction of defective vision in a plane lying in the vertex of the cornea, and at least two radii r1 and r2 satisfy the equation B(r=r1,φ)≠B(r=r2,φ).
