Newsclip: Dry eye after PRK and 'sub bowmans keratomileusis'

Doctors reported at ASCRS in San Diego that the incidence of dry eye after PRK is comparable to that of 'sub bowman's keratomileusis', a new 'thin-flap' procedure using Intralase.

Dr. Stahl and colleagues examined 50 non-dry eye patients who underwent SBK in one eye and PRK in the contralateral eye. SBK flaps were created with an IntraLase femtosecond laser (Advanced Medical Optics) with a target thickness of 100 µm, she said.

"We've known historically that PRK has fewer dry eye symptoms than traditional LASIK," she said. "We wanted to assess the incidence and severity of dry eye findings and symptoms between a new thin-flap IntraLase procedure, which we're calling sub-Bowman's keratomileusis, and PRK."
