Corneal Epithelial Defects and Intraoperative Aberrometry

In this 1-Minute Video, Dr. John Hovanesian demonstrates how corneal epithelial defects can shift a patient’s aberrometry using 2 cases. In his first example, discrepancies between preoperative and ocular response analyzer (ORA) keratometry were caused by forceps grazing the cornea. A second case involved a preoperative corneal defect that altered the cylindrical recommendation of ORA during surgery. Dr. Hovanesian cautions physicians to carefully interpret intraoperative aberrometry in the presence of corneal epithelial defects.
