Claim 0:
1. An apparatus for performing an ocular laser surgical procedure, comprising:
a laser configured to emit a pulsed laser beam;
optical elements configured to focus the pulsed laser beam emitted by the laser at a desired position on an eye of a patient; and
a controller configured to control the laser and the optical elements to:
establish a cutting pattern comprising a plurality of photodisruption points, including a first 2D raster scan pattern, a second 2D raster scan pattern, and a 3D scan pattern, wherein the first 2D raster scan pattern is formed by a set of first photodisruption points, a set of second photodisruption points and a plurality of additional photodisruption points between the set of first photodisruption points and the set of second photodisruption points, the second 2D raster scan pattern is formed by a set of third photodisruption points, a set of fourth photodisruption points and another plurality of additional photodisruption points between the set of third photodisruption points and the set of fourth photodisruption points, the first and second 2D raster scan patterns extend in a common plane parallel to a first direction and are displaced relative to each other along the first direction, the 3D scan pattern is a volume formed by photodisruption points and extends both in the plane and in a second direction perpendicular to the plane, and the 3D scan pattern overlaps with the set of second photodisruption points and the set of third photodisruption points; and
direct the pulsed laser beam to make a raster lamellar cut according to the cutting pattern, wherein the raster lamellar cut includes two 2D raster regions corresponding to the first and second 2D raster scan patterns and a 3D laser pattern corresponding to the 3D scan pattern, and wherein the 3D laser pattern is located between the two 2D raster regions and connects the two 2D raster regions to form the raster lamellar cut.
