Even in eyes with preoperative risks, penetrating keratoplasty (PKP) can achieve favorable results for the corneal complications of herpes zoster ophthalmicus (HZO), researchers say, as reported by Reuters.
“What we learned is corneal transplants can make a significant difference in visual acuity, but it’s important to control inflammation before transplant,” Dr. Christopher Hood of the University of Michigan in Ann Arbor, said in an email to Reuters Health. “We emphasize the importance of operating on a quiet eye.”
Dr. Hood and colleagues studied 53 eyes of 53 patients who underwent PKP due to corneal complications of HZO. The mean age at the time of PKP was 68; 68% were women and almost all were white. The mean quiescent period was 6.5 years from HZO to PKP.
