Abstract
Systems and methods apply pulsed laser energy to an eye with a pulsed laser system. The laser system includes a pulsed laser, a laser beam delivery system and at least one processor. The laser makes a beam of an ablative light energy. A dimension across the laser beam varies during a treatment of the eye. A firing rate of the laser varies as the dimension across the beam varies during the treatment. The dimension across the beam and the firing rate of the laser can be arranged so as to maintain a power of the beam applied to the eye at a substantially constant level during at least a portion of the treatment. A firing rate of the laser for each pulse may be listed in a treatment table.
