Abstract: Embodiments of the present invention generally describe systems, devices, and methods for directly measuring pulse profiles during pulse delivery. In some embodiment, the pulse profiles may be measured while the pulse is delivered to ablate a material. Embodiments, may calculate ablation spot parameters based on the pulse profiles and may refine one or more subsequent laser pulses based on deviations from the calculated ablation spot parameters from desired ablation spot parameters. In some embodiments, a fluence profiler is provided. The fluence profiler may measure a pulse profile of a laser pulse from a portion of the laser pulse. The fluence profiler may utilize a UV radiation energy sensor device and a camera-based imager. The measurements from the UV radiation energy sensor device and the camera-based imager may be combined and scaled to provide a measured pulse profile that corresponds to the delivered pulse.

Abstract: Systems and methods to treat a region of a cornea of an eye having an epithelial layer disposed over a stromal layer. Exemplary techniques include the administration of epithelial sequence ablation laser pulses and stromal sequence ablation laser pulses to the eye. A treatment laser generates a laser beam for ablation of eye tissue, and a movable scan component scans the laser beam over the region. A processor system is coupled to the laser and the movable scan component, and the processor system is configured to arrange pulses of laser beam to treat the epithelial and stromal layers of the region.

Abstract: Systems, methods, and computer program products are provided for the administration of ablation profiles during refractive surgery treatments. Basis data framework techniques enable the implementation of ablation profiles having various shapes, resulting in increased ablation efficiency when treating certain vision conditions. Exemplary basis data architecture approaches are configured to efficiently operate with annular, elliptical, and slit laser beam shapes, for example, and to account for position-dependent ablation features.
