Advanced Medical Optics has voluntarily recalled COMPLETE MoisturePLUS Multi Purpose Solution. The action was taken as a precaution because of reports of a link between the solution and a serious eye infection, Acanthamoeba keratitis (AK). This infection is difficult to treat and can lead to vision loss in some patients, and may even necessitate a corneal transplant in certain cases. Symptoms of AK may include eye pain or redness, blurred vision, light sensitivity, the sensation of something in the eye or excessive tearing. The Center for Disease Control and Prevention (CDC) determined that the risk of developing AK was at least seven times greater than the national average for consumers who used Complete MoisturePlus Solution.
