Federal health officials are hearing stories of pain and frustration from patients harmed by Lasik eye surgery.
At a public hearing Friday, officials heard stories of eye pain and blurred or double vision because of the procedure.
One man who had Lasik in 1998 says he has "not experienced a moment of crisp, good quality vision since."
Most Lasik recipients do walk away with crisper vision, but others suffer life-changing side effects like poor vision even with glasses or the inability to see or drive at night.
The Food and Drug Administration is taking a new look at whether warnings about its risks are appropriate, and pairing with eye surgeons for major study to better understand who has bad outcomes and why.
