Abstract

Recently, two papers “Dorronsoro et al., Experiment on PMMA models to predict the impact of corneal refractive surgery on corneal shape, Opt. Express 14, 6142 (2006)” and “JR Jiménez et al., Deviations of Lambert-Beer’s law affect corneal refractive parameters after refractive surgery, Opt. Express 14, 5411 (2006)” have been published on an important question in corneal refractive surgery: to explain the differences between post-surgical corneal elevation maps and those predicted after theoretical ablation. An analysis of Dorronsoro et al. data demonstrates that the failures in Lambert-Beer’s law could be in the origin of shape discrepancies. New models and experimental data on deviations of Lambert-Beer’s law might help to minimize post-surgical corneal discrepancies and thus optimise eye emmetropization.
