    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.

    Abstract: A system and method for performing ophthalmic surgery using an ultra-short pulsed laser is provided. The system includes a laser engine configured to provide an ultra-short pulsed laser beam, optics configured to direct the laser beam to an undocked eye of a patient, an eye tracker configured to measure five degrees of freedom of movement of the undocked eye, an optical coherence tomography module configured to measure depth of the undocked eye, and a controller configured to control laser beam position on the undocked eye toward a desired laser pattern based on depth and the five degrees of freedom of movement of the undocked eye. Adaptive optics are also provided. Also disclosed are a scleral ring including fiducial markings and a compliant contact lens and fluid tillable contact lens configured to facilitate ultra-short pulsed laser surgery while reducing or eliminating eye docking requirements.
