Ray-Tracing Prediction of Intraocular Lenses Power: Effect of Corneal Aberrations


The standard estimation of the required power of intraocular lenses (IOLs) based in empirical correlations have serious limitations especially in patients with elevated corneal aberrations. This is the case in cataract patients that underwent LASIK refractive surgery. We developed an improved procedure based in customized ray-tracing to predict the optimum IOL power. It was applied to both normal and post-LASIK patients and the impact of the corneal aberrations evaluated.
