Preoperative corneal thickness helps predict flap thickness

San Francisco-Preoperative corneal thickness is the most important predictor of achieved flap thickness using the Hansa-tome (Bausch & Lomb) microkeratome, but preoperative spherical equivalent (SE) and microkeratome head choice also play a role, according to the results of a study presented by Jay S. Pepose, MD, PhD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
