The invention relates to a method for providing control data of an ophthalmic surgical laser of a treatment device for removing tissue from a human or animal cornea. The method comprises: determining an expected temperature distribution of each laser pulse in the cornea; a laser pulse sequence of a predetermined laser pulse distribution for removing the tissue is determined from a temperature model of the cornea, the respective laser pulse position in the cornea being predetermined by the laser pulse distribution and the respective laser pulse position in the cornea being predetermined by a laser predetermined pulse sequence, a predetermined laser pulse position is irradiated with a corresponding laser pulse in this order, a temperature curve of the cornea is calculated from the cumulative temperature distribution of the laser pulses in the temperature model, and a difference curve to a predetermined limit temperature curve is determined, and wherein the order of the laser pulses is determined from a differen
