Abstract
Laser eye surgery systems, methods, and devices makes use of a two-pivot scanning system for laterally deflecting the laser beam across the corneal surface to provide X-Y scanning. An imaging lens pivots about two eccentric axes extending along, but disposed beyond the laser beam. As the lens pivots, the beam will follow a substantially arc-shaped path. The eccentric axes are offset about the laser beam axis by about 90°, and the system controller can compensate for the arc-shaped path deflections by adjusting the angular position of the imaging lens about complementary stage.
