摘要

We have tested whether a recent model [Appl. Phys. Lett. 95, 174105 (2009)] that considers the angular dependencenof laser-ablation rates, including reflection losses and geometrical dependence of incident fluence, and the effect ofnplume absorption can have significant effects for refractive surgery patients. We have developed a mathematicalnprocedure and deduced equations that show that this model can significantly influence postsurgical corneal para-nmeters (radius and asphericity) and, thus, should be considered in ablation algorithms in order to achieve a betternemmetropization and an effective correction of eye aberrations. © 2010 Optical Society of America
