PERFORMANCE AND ACCURACY ASSESSMENT SYSTEM FOR REFRACTIVE LASER SYSTEMS AND ASSOCIATED METHODS

摘要

A method for assessing a performance of a laser system for use in corneal ablation is provided that includes directing a beam of laser shots onto a fluorescent indicator. The indicator is adapted to emit a first wavelength of light different from a second wavelength of light impinging thereon. The directing step is performed in a plane of a cornea of an eye desired to be ablated and also onto a cornea positioned at the corneal plane. Light reflected from the indicator is detected, and a difference between a detected light pattern from the camera and a predetermined ablation pattern desired to be made on the cornea is calculated. The predetermined pattern is then corrected to compensate for the calculated difference.
