    摘要: 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 accuracy when treating certain vision conditions. Exemplary basis data architecture approaches are configured to efficiently operate with annular, elliptical, and slit laser beam shapes.

    摘要: A laser system calibration method and system are provided. In some methods, a calibration plate may be used to calibrate a video camera of the laser system. The video camera pixel locations may be mapped to the physical space. A xy-scan device of the laser system may be calibrated by defining control parameters for actuating components of the xy-scan device to scan a beam to a series of locations. Optionally, the beam may be scanned to a series of locations on a fluorescent plate. The video camera may be used to capture reflected light from the fluorescent plate. The xy-scan device may then be calibrated by mapping the xy-scan device control parameters to physical locations. A desired z-depth focus may be determined by defining control parameters for focusing a beam to different depths. The video camera or a confocal detector may be used to detect the scanned depths.
