Abstract:
A method and apparatus for performing ophthalmic laser surgery using a pulsed laser beam is provided. The method includes establishing an initial cutting pattern comprising a plurality of original photodisruption points, establishing an enhanced cutting pattern comprising a plurality of enhanced photodisruption points selected to decrease potential adverse effects due to patient movement and having increased density over a fixed area as compared with the plurality of original photodisruption points, and performing an ocular surgical procedure according to the enhanced cutting pattern. Enhanced cutting patterns may include circular cuts around the periphery of a capsule, vertical side cuts for lens fragmentation, raster lamellar cuts, and grid lamellar cuts. Each photodisruption point in the initial cutting pattern and the enhanced cutting pattern comprises a laser target point.
