Advanced Medical Optics (AMO) has issued a voluntary recall on all Complete MoisturePlus contact lens solutions after information received today from the US Centers for Disease Control and Prevention (CDC) revealed so far that 46 patients with soft contact lenses developed Acanthamoeba keratitis (AK) since January 2005. A total of 39 of those reports were from wearers of soft contact lenses, and 21 were using a Complete MoisturePlus contact lens solution.
Acanthamoeba is a micro organisms commonly found in water, sewage systems, cooling towers, soil, and air conditioning units. Acanthamoeba keratitis (AK) is a serious infection of the cornea as a result of contact to this micro organism.
Contact lens wearers should consult with their eye doctor if they have any of the following symptoms: Pain, redness, blurred vision, deteriorating vision, blindness, sensitivity to light, sensation of something in the eye, and excessive tearing. The symptoms, which can last several weeks to months, are not the same for everybody. Early in the infection, the symptoms of AK can be very similar to the symptoms of other more common eye infections.
AK may eventually cause severe pain and possible vision loss with some patients requiring a corneal transplant if left untreated.
