Abstract

Purpose: : We calculate whether deviations of Lambert–Beer’s law, which regulates depth ablation during corneal ablation, significantly influences visual performance after corneal refractive surgery.

Methods: : For this, we compute a point–to–point correction on the cornea while assuming a non–linear (including a quadratic term) fit for depth ablation.

Results: : Post–surgical equations for refractive parameters using a non–linear fit show significant differences with respect to parameters obtained from a linear fit (Lambert–Beer’s law). Differences were also significant for eye aberrations.

Conclusions: : These results show that corneal–ablation algorithms should include information on deviations from Lambert–Beer’s law for achieving an accurate eye correction.

Keywords: refractive surgery: LASIK • refractive surgery: comparative studies • refractive surgery: optical quality
