A laser beam ophthalmological surgery method for ablating a cornea of a patient\s eye includes the steps of generating a laser beam and directing the generated laser beam onto a scanner and scanning the laser beam in a random scanning pattern with a generated random scanning pattern signal on the surface of the cornea of a patient to ablate the surface of the cornea of a patient\s eye. A computer generates the random pattern laser beam control signal which controls the scanner to scan in the random scanning pattern over the cornea and includes selecting a database of non-random scanning points to scan the laser beam onto the cornea of a patient\s eye and then randomly select the non-random scanning points for the random scanning of predetermined scanning points. A laser ophthalmological surgery apparatus is provided which includes a laser for generating a laser beam along with a scanner positioned for receiving the laser beam and producing a predetermined scanning pattern onto the cornea of an eye. A computer is used to generate a random scanning pattern signal and is connected to the scanner for controlling the scanner in a random overlapping scanning beam pattern over a predetermined area.
