We calculate whether deviations of Lambert–Beer’s law, which regulates depth ablation during corneal ablation, significantly influences visual performance after corneal refractive surgery.
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.
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.
These results show that corneal–ablation algorithms should include information on deviations from Lambert–Beer’s law for achieving an accurate eye correction.
