The micro-organism causes acanthamoeba keratitis (AK), a serious corneal infection with symptoms that differ among patients. Symptoms range from redness and sensitivity to light to severe pain and possible vision loss. If left untreated, some patients may even require a corneal transplant.
The CDC interviewed 46 patients in the U.S. who had developed AK since January 2005. Thirty-nine of those patients wore soft contact lenses and 21 of them reported using Complete All-In-One MoisturePlus.
