ABSTRACT:
A laser beam ophthalmological surgery method includes the steps of generating a laser beam and splitting the generated laser beam into multiple laser beams which are simultaneously focused onto a plurality of scanners. Each scanner in turn produces a predetermined scanning pattern focused on the cornea of a patient's eye to ablate the cornea tissue and with at least two beams simultaneously scanning and ablating the cornea tissue. Scanning is controlled from a central processing unit to perform the surgical procedure, removing a laser thickness of the cornea tissue to provide a safer and more predictable surgical procedure in the reshaping of the cornea. A laser ophthalmological surgery apparatus is provided which includes a laser generating a laser beam, a beam splitter for splitting the laser beam into a plurality of laser beams, and a plurality of scanners, each positioned for receiving one of the laser beams from the beam splitter and producing a predetermined scanning pattern from the laser beam and impinging the scanning pattern upon the cornea of a patient's eye.
