Here are some relevant quotes from the FDA study for you.
In each of the PROWL studies, less than 1 percent of patients experienced difficulty performing their usual activities following LASIK surgery due to any one symptom.
...
* Up to 46 percent of participants, who had no visual symptoms before surgery, reported at least one visual symptom at three months after surgery.
* Participants who developed new visual symptoms after surgery, most often developed halos. Up to 40 percent of participants with no halos before LASIK had halos three months following surgery.
* Up to 28 percent of participants with no symptoms of dry eyes before LASIK, reported dry eye symptoms at three months after their surgery. This is consistent with previous studies.
* Less than 1 percent of study participants experienced "a lot of difficulty" with or inability to do usual activities without corrective lenses because of any one visual symptom (starbursts, ghosting, halos, glare) after LASIK surgery.
* More than 95% of participants were satisfied with their vision following LASIK surgery.
Participants were more than twice as likely to report their visual symptoms on a questionnaire than to tell them to their health care provider
