The National Eye Institute (NEI) is the division of the National Institutes of Health (NIH) dedicated to vision research. Recently, the FDA, working in conjunction with the NEI, developed a very sophisticated method to test outcomes after contemporary LASIK laser vision correction eye surgery. This study of the results of modern LASIK is called the Patient Reported Outcomes With LASIK, or PROWL, Study. Ed Manche, M.D., the Director of Refractive Surgery at Stanford University called the study “incredibly well designed.” This study looked at the rates of glare after LASIK in both a navy population of patients and a civilian population of patients. In both arms of the study, glare was decreased at 3 month after LASIK compared to levels of glare prior to surgery with glasses or contacts. Noted refractive surgeon Eric Donnenfeld, M.D. said, “What I learned from PROWL is that LASIK actually reduces the severity and incidence of glare and halos.”
