Cutting-edge wave front aberrometry can be used to help refractive surgeons predict the biomechanical stability of the cornea after LASIK surgery. "We all want to identify corneas that are weaker, even if they don't have any topographic abnormalities," Marcony Santhiago, MD, from the Federal University of Rio de Janeiro, Brazil, told Medscape Medical News. In their study, Dr. Santhiago and colleagues identified 8 mathematical variables that correlate with easily measured structural parameters of the pre- and postoperative cornea.
