Hemorrhage complicating YAG laser feeder vessel coagulation of cornea vascularization.
A neodymium:yttrium-aluminum-garnet (Nd:YAG) laser was used in the thermal mode to coagulate blood vessels in a patient with a vascularized corneal leukoma in an attempt to reduce neovascularization before penetrating keratoplasty. Occlusion of the feeder artery at the periphery was followed by a large stromal hemorrhage. A successful keratoplasty was performed 2 days later.
