Abstract: Techniques, systems are described for performing laser eye surgery. In one aspect, a method for improving an optical function of an eye includes preparing the eye for surgery by determining an optical characteristic of the eye. Laser marking pulses are applied to generate a laser mark in a region of the eye in relation to the determined optical characteristic. Also, a surgical procedure is performed in a surgical region selected in relation to the generated laser mark.
