Abstract
A method for providing control data for an eye surgical laser of a treatment apparatus for removing tissue is disclosed. The method includes utilizing a control device for determining a corneal geometry and an ocular wavefront of a human or animal eye from predetermined examination data. A corneal wavefront is then determined from the corneal geometry using a physical model, and an internal wavefront is calculated from a difference between the ocular wavefront and the corneal wavefront. A wavefront to be achieved is calculated from a difference of a preset target wavefront and the calculated internal wavefront. A target corneal geometry is determined from the wavefront to be achieved by the physical model, and a tissue geometry to be removed is calculated from a difference of the corneal geometry and the target corneal geometry, and control data for controlling the eye surgical laser is provided.
