Claim 13:
14. A method comprising:
directing, by a scanner system, a pulsed laser beam along a scanning treatment line in eye tissue at a treatment speed;
deflecting the pulsed laser beam, using a first scanning apparatus connected upstream of the scanner system to produce a first scanning movement component in a first scanning direction at a first scanning speed, wherein the first scanning speed is higher as compared to the treatment speed, wherein the first scanning movement component is superposed on the scanning treatment line;
deflecting the pulsed laser beam, using a second scanning apparatus connected upstream of the scanner system to produce a second scanning movement component, in a second scanning direction, which is at an angle to the first scanning direction of the first scanning movement component, at a second scanning speed, wherein the second scanning speed is higher as compared to the treatment speed, wherein the second scanning movement component is superposed on the first scanning movement component and a scanning region is treated by the deflection of the pulsed laser beam with the first scanning movement component in the first scanning direction and the superposed, second scanning movement component in the second scanning direction; and
moving, by the scanner system, the scanning region along the scanning treatment line, wherein the scanner system is controlled using a circuit in synchronized fashion with the first scanning apparatus and the second scanning apparatus,
wherein treatment of a lenticular tissue volume in the eye is effected by the deflection of the pulsed laser beam with the first scanning movement component in the first scanning direction, the deflection of the pulsed laser beam with the superposed, second scanning movement component in the second scanning direction, and direction of the pulsed laser beam along the scanning treatment line, wherein the lenticular tissue volume is greater than a width of the pulsed laser beam.
