WASHINGTON (October 15, 2009)—The U.S. Food and Drug Administration says it is beginning a study of problems resulting from laser eye-correcting surgery, which include blurred vision and dry eyes.

The FDA said it will work with the National Eye Institute and the Department of Defense to determine the percentage of patients who experience negative side effects following surgery.

The project includes a clinical trial, tracking patients who undergo the procedure, which is expected to conclude by 2012.

“This study will enhance our understanding of the risks of Lasik and could lead to a reduction in patients who experience adverse effects," said Dr. Jeffrey Shuren, FDA's acting medical device chief.
