AS-OCT can help fine-tune surgical maneuvers, modifications for repeat keratoplasty

NEW ORLEANS — A study evaluating an optical coherence tomography-based protocol for the management of failed penetrating keratoplasty determined that imaging of the anterior segment after failure improves planning for repeat surgery, according to a poster presentation here. Fifty-five patients with a failed graft were included in the study, with their primary inclusion factor being corneal scar. In total, 440 graft-host junctions were analyzed using the Visante AS-OCT (Carl Zeiss Meditec) for anterior/posterior malapposition, according to the poster at the American Academy of Ophthalmology meeting.
