1. A laser system to treat an eye with a laser beam, comprising:

  • a laser to generate the laser beam;

    a tomography system to generate a measurement beam and measure at least one surface of the structure of the eye;

    an optical delivery system coupled to the laser and the tomography system to deliver the laser beam and the measurement beam to the eye;

    a memory storing therein a look-up table, the look-table including first data which maps locations within the eye to one or more control parameters for the laser, and further including second data which maps the locations within the eye to one or more control parameters for the tomography system; and

    a processor coupled to the laser, the tomography system, and the optical delivery system, the processor comprising a tangible medium embodying instructions to;

    in response to the first data in the look-up table, mark the eye at one or more mark locations corresponding to each of one or more target locations, the one or more target locations being disposed at of one or more of a cornea, an aqueous humor, an iris, an anterior lens capsule, an anterior lens capsule, a posterior lens capsule, a cortex, or a nucleus,in response to the second data in the look-up table, measure with the measurement beam a measured location for each of the one or more marks, andcompare the corresponding target location with the measured location for each of the one or more marks in order to determine one or more of calibration of the laser system or eye position.
