We collected data on anterior corneal astigmatism (ACA) and root mean square (RMS) values for anterior corneal lower\u2010 (LoA) and higher\u2010order aberrations (HoA) as corneal optical properties using AS SS\u2010OCT. Using preoperative ACA and four pterygial morphological profiles (horizontal invasion length [HIL], height, thickness and the ratio of residual corneal thickness [RCT] to central corneal thickness [CCT]) measured in AS SS\u2010OCT, we plotted receiver operating characteristic (ROC) curves. These curves aimed to determine cut\u2010off values predicting a perioperative decrease exceeding 50% in ACA, RMS LoA and RMS HoA, as well as postoperative residual ACA higher than 1.25D.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Preoperative ACA\u2009&gt;\u20091.42D (AUC\u2009=\u20090.934) and\u2009&gt;3.60D (AUC\u2009=\u20090.946) proved most effective in identifying subjects with perioperative decrease exceeding in ACA and RMS LoA, respectively.
