Abstract
An ophthalmic surgical laser system and method for forming a lenticule in a subject's eye using 'fast-scan-slow-sweep' scanning scheme. A high frequency scanner forms a fast scanline, which is placed tangential to a parallel of latitude of the surface of the lenticule and then moved in a slow sweep trajectory along a meridian of longitude of the surface of the lenticule in one sweep. Multiple sweeps are performed along different meridians to form the entire lenticule surface, with the orientation of the scanline rotated between successive sweeps. To reduce acceleration and jerk in the XY stage motion, especially during transition from one sweep to the next, the sweeping speed profile is a sigmoid function.
