In a method of generating a control program, according to which a laser-beam spot is guided, while being controlled with respect to position and time, over a cornea to be corrected photorefractively, so as to ablate a predetermined ablation profile therefrom, the effect of the angle between the laser beam and the corneal surface on the energy density of the laser-beam spot incident on the corneal surface and/or on the fraction of the laser-beam energy incident on the corneal surface which is reflected away, is taken into account when generating the control program.

Laser surface ablation methods and apparatus are disclosed reprofiling surfaces astigmatically. An optical system includes cylindrically-powered elements to form an elliptical laser irradiation pattern on a target surface. By successively altering the area of the elliptical irradiation, an astigmatic, bi-powered ablation profile is achieved. Preferably, the invention is used with an excimer laser for excimer laser keratoplasty, keratomileusis or other ablative eye surgeries.
