20/20 Vision in the Blink of An Eye

The FDA said it could take as many as three to six months for vision to stabilize after surgery. During that time, the agency noted that people may experience glare and halos, and have a difficult time driving at night. The FDA also outlines the risks associated with Lasik on its Web site.

For good candidates, those with thick enough corneas and healthy eyes, Rubinfeld said the complications are rare. He said he rejects about 10 percent of patients for Lasik on a given day.

Still, patients like Burch said clinical trials failed to inform her that Lasik patients were losing contrast sensitivity, which enables people to distinguish an object from its background.

"I feel like someone threw sand in my eyes every day," said Burch, who now works for a branch of the National Institutes of Health. "My eyes sting and burn."

Shawna Tunnell, a 42-year-old attorney, who had worn glasses since age 4, said her experience proved otherwise. Tunnell recently had Lasik after her colleagues raved about the procedure.

Tunnell said she had "a little discomfort in the eyes" but has otherwise been happy with the results.

"It's amazing to see you without thick glasses or contacts," she said.

In the past 10 years, Rubinfeld and other doctors said Lasik technology has improved. Now surgeons are also more experienced than ever before with the procedure.

"When we look at outcomes of Lasik -- 20/20 rates -- our outcomes of Lasik today are better than they have ever been," South Carolina's Solomon said. "The technology has advanced to the point that there has never been a better time to undergo Lasik eye surgery. Our outcomes are better and these procedures are safer."
