DEAR DR. ROACH: I was considering LASIK surgery for my eyes, but I recently saw some concerning information on the news that makes me doubt the safety of the procedure. Is it safe? - L.B.
ANSWER: With 20 million or so procedures done in the U.S., LASIK is a commonly performed surgery. It corrects refractive error so that a person can see clearly without glasses. A laser is used to cut a flap of cornea, and the cornea is reshaped to allow for correct vision, then the flap is replaced. For most patients, it is a painless procedure with almost immediate visual recovery. In a review of large studies, more than 95% of people who have undergone LASIK reported being satisfied with their outcomes.
