Ocular and Optical Coherence Tomography-Based Corneal Aberrometry in Keratoconic Eyes Treated by Intracorneal Ring Segments

OCT is a reproducible technique to evaluate corneal aberrations. OCT-based corneal aberrations and ocular aberrations show a high correspondence in keratoconic patients before and after ICRS implantation. ICRS produced a decrease in astigmatism, but on average did not produce a consistent decrease of HOAs.
