1. A system to ablate an eye to remove an epithelial layer of the eye, the system comprising:

  • a laser to generate a beam or an ablative radiation;

    a movable scan component configured to scan the laser beam over a region of the eye to ablate the epithelial layer;

    a sensor to measure fluorescent light and generate a signal when the beam of ablative radiation irradiates the eye;

    a processor system comprising a tangible medium and a memory, the processor system coupled to the laser, the movable scan component and the sensor, the processor system configured to scan the beam of ablative radiation in response to the signal and within the region in accordance with a pulse sequence, and wherein the processor system is configured to sort the pulse sequence to enhance the signal based on a tissue fluorescence of the epithelial layer in response to the ablative radiation.
