CDC Releases Early Report of Serious Eye Infections Associated with Soft Contact Lens Solution

Tuesday - May 29, 2007

The Centers for Disease Control and Prevention (CDC), collaborating with the Food and Drug Administration, state and other partners, has identified an outbreak of a serious but rare eye infection called Acanthamoeba keratitis (AK). This infection is caused by a free-living ameba (Acanthamoeba) a microscopic organism found everywhere in nature. Infections can result in permanent visual impairment or blindness. AK primarily affects otherwise healthy people, most of whom wear contacts lenses. In the United States, an estimated 85% of cases of this infection occur in contact lens users. The incidence of the disease in the U.S. is approximately one to two cases per million contact lens users.
