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.

Abstract: In laser-assisted corneal lenticule extraction procedures, the lenticule incision profile includes anterior and posterior lenticule incisions, with one or more of the following features: plano transition zone outside the optical zone, to improve mating of anterior and posterior incision surfaces after lenticule extraction; shallow arcuate incisions above the anterior incision and near the lenticule edge, to improve surface mating; separate ring cut intersecting the anterior and posterior incisions in the transition zone, to reduce tissue bridges and minimize tear at the lenticule edges and facilitate easy lenticule extraction; larger posterior incision, which includes a pocket zone outside the lenticule edge, for better surface mating and bubble management during cutting; and a separate ring shaped pocket cut intersecting the pocket zone of the posterior incision, for bubble management. An entry cut can intersect either the pocket zone of the posterior incision or an entry extension zone of the anterior incision.
