Abstract:
1. A method of laser corneal ablation comprising: generating a laser-beam profile having one or more elementary laser beams; projecting the laser-beam profile onto a cornea and thereby ablating a predetermined ablation profile from the cornea; and adjusting the laser-beam profile according to an effect of an angle between the one or more elementary beams of the laser-beam profile and a surface of the cornea on an energy density of the laser-beam profile on the surface of the cornea; wherein adjusting the laser-beam profile further comprises increasing a time interval that at least one elementary beam is incident on the corneal surface at an incident point of the corneal surface as a function of the distance of the incident point of the elementary beam center on the cornea from an axis running parallel to the elementary beam direction, which axis meets the corneal surface at a substantially right angle.
