UNIFORM LARGE AREA ABLATION SYSTEM AND METHOD

摘要

Methods and devices for performing corrective eye surgery generally direct a laser beam at a target region of a patient's eye (118) with the laser beam (114) having a non-uniform energy distribution profile. As ablation rates vary locally across the beam cross-section (34), the energy distribution profile is tailored to effect a uniform ablation depth (20) with each laser pulse of an excimer laser system.
