Abstract: A method of cataract surgery in an eye of a patient includes identifying a feature selected from the group consisting of an axis, a meridian, and a structure of an eye by corneal topography and forming fiducial mark incisions with a laser beam along the axis, meridian or structure in the cornea outside the optical zone of the eye. A laser cataract surgery system a laser source, a topography measurement system, an integrated optical subsystem, and a processor in operable communication with the laser source, corneal topography subsystem and the integrated optical system. The processor includes a tangible non-volatile computer readable medium comprising instructions to determine one of an axis, meridian and structure of an eye of the patient based on the measurements received from topography measurement system, and direct the treatment beam so as to incise radial fiducial mark incisions.

Abstract: A laser eye surgery system includes a laser to generate a laser beam. A spatial measurement system generates a measurement beam and measure a spatial disposition of an eye. A processor is coupled to the laser and the spatial measurement system, the processor comprising a tangible medium embodying instructions to determine a spatial model of the eye in an eye coordinate reference system based on the measurement beam. The spatial model is mapped from the eye coordinate reference system to a machine coordinate reference system. A laser fragmentation pattern is determined based on a plurality of laser fragmentation parameters. The laser fragmentation pattern and the spatial model is rotated by a first rotation angle such that the spatial model is aligned with the reference axis of the machine coordinate reference system and the rotated laser fragmentation pattern is aligned with the corneal incision.
