Method for providing control data for an opthalmological laser of a treatment apparatus

A method for providing control data for an ophthalmological laser of a treatment apparatus for treating a cornea, which has been treated with a cross-linking method, wherein the method comprises the following steps performed by a control device:

• setting conventional laser parameters for removing a predetermined correction volume from the cornea, wherein the laser parameters include at least a laser pulse energy and a number of laser pulses of the laser;
• providing laser parameters increased in power in areas of the correction volume, in which change to the cornea by the cross-linking method is expected, wherein the laser parameters increased in power have a higher laser pulse energy and/or a higher number of laser pulses compared to the conventional laser parameters;
• and
• providing the control data, which includes the laser parameters increased in power in the areas of the correction volume in which change to the cornea by the cross-linking method is expected and the conventional laser parameters in remaining areas of the correction volume.
