Performance assessment system for refractive lasers and associated methods
First Claim
1. A system for assessing a performance of a laser system for use in corneal ablation, the system comprising:
- a support adapted to hold an ablation substrate;
an optical system for directing a laser beam onto the ablation substrate in a plane of a cornea of an eye desired to be treated to ablate the ablation substrate in a predetermined pattern;
an optical scanner for directing a beam of light across the ablated substrate and for receiving light reflected therefrom to detect an actual ablated pattern;
an analyzer for comparing the detected ablated pattern with the predetermined ablation pattern; and
a display in signal communication with the analyzer for displaying to a user a comparison of the detected ablated pattern and the predetermined ablation pattern.

Abstract
A method for assessing a performance of an ablation laser system includes ablating a substrate surface to achieve a predetermined ablation pattern. A beam of light is directed across the ablated substrate, and reflected light is received to detect an actual ablated pattern, which is compared with the predetermined ablated pattern. The resulting comparison is displayed to a user so that the performance of the laser system can be assessed. A system includes a support that is adapted to hold an ablation substrate at a treatment plane. An optical scanner directs a beam of light across the ablated substrate and receives light reflected therefrom to detect an ablated pattern. An analyzer compares the detected with a predetermined ablated pattern. A display in signal communication with the analyzer displays a comparison of the detected and the predetermined ablated pattern.
