Early Report Of Serious Eye Infections Associated With Soft Contact Lens Solution
Centers for Disease Control and Prevention has identified an outbreak of a serious but rare eye infection called Acanthamoeba keratitis.
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 contact 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.
CDC has received reports of 138 cases of culture-confirmed AK in 35 states and Puerto Rico, with complete patient data available for 46 case-patients.
