The American Society of Cataract and Refractive Surgery takes the study of the risks and benefits of LASIK surgery seriously, and we are very concerned about patients who have had negative outcomes. We support additional research to determine why these occur and how best to resolve them. We know that while LASIK, like all surgeries, does have some risks, unresolved, long-term issues are extremely rare and LASIK is one of the safest most effective procedures available. Extensive research has shown that more than 95 percent of the millions of people worldwide who have had LASIK surgery are satisfied with their results. Those studies also show that even patients who experienced side effects such as dry eye and night vision issues became satisfied when their symptoms were addressed and resolved by a doctor.
