We have tested whether a recent model [Appl. Phys. Lett.95, 174105 (2009)APPLAB0003-695110.1063/1.3254236] that considers the angular dependence of laser-ablation rates, including reflection losses and geometrical dependence of incident fluence, and the effect of plume absorption can have significant effects for refractive surgery patients. We have developed a mathematical procedure and deduced equations that show that this model can significantly influence postsurgical corneal parameters (radius and asphericity) and, thus, should be considered in ablation algorithms in order to achieve a better emmetropization and an effective correction of eye aberrations.
我们已经测试了一个最近的模型[Appl. Phys. Lett.95, 174105 (2009)APPLAB0003-695110.1063/1.3254236]，该模型考虑了激光烧蚀率的角度依赖性，包括反射损失和入射通量的几何依赖性，以及羽流吸收的影响，这可能对屈光手术患者有显著影响。我们已经开发了一种数学程序，并推导出了一些方程，这些方程表明，这个模型可以显著影响术后角膜参数（曲率半径和非球面性），因此，应该在消融算法中考虑这个模型，以实现更好的屈光正常化和有效矫正眼睛像差。
