| 摘要 |
The present invention provides methods, systems, and apparatus (10) for calibrating a laser ablation system, such as an excimer laser system (11) for selectively ablating a cornea of a patient's eye. The invention also facilitates alignment of eye tracking cameras (36, 38) that measure a position of the eye during laser eye surgery. A calibration and alignment fixture (20) for a scanning laser beam delivery system (12) having eye tracking cameras (36, 38) may include a structure (20) positionable in a treatment plane. The structure (20) having a feature (28) directing laser energy incident thereon to a calibration energy sensor (22), at least one reference-edge (32, 34) to determine a characteristic of the laser beam (shape, dimensions, etc.), and an artificial pupil (40) to determine alignment of the eye tracking cameras (36, 38) with the laser system (10).
