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 scan line, which is placed tangential to a parallel of latitude of the surface of the lenticule and then 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 scan line rotated between successive sweeps. To generate tissue bridge free incisions without leaving laser-induced marks in the eye, a laser pulse energy between 40 nJ to 70 nJ is used, and the sweeping speed is controlled such that the scan line step (the distance between the centers of consecutive scan lines) is between 1.7 μm and 2.3 μm.
