One year after Bausch & Lomb’s Renu contact lens solution was pulled from the market because of an ineffective disinfectant alexidine, another company has withdrawn its products. Adavanced Medical Optics of Santa Ana California has pulled its AMO Complete Moisture Plus Multi-Purpose Solution from the market after the product was linked with a rare but very dangerous infection causing amoeba known as acanthamoeba keratitis. Advanced Medical Optics withdrew its contact lens solution after the Centers for Disease Control and Prevention in Atlanta identified 138 laboratory confirmed cases of the infection Acanthamoeba keratitis that have occurred throughout the country since January 2005. The CDC had not determined how the infection occurred but they did say that the risk of developing infection was at least 7 times greater for those people who used the AMO product thant for those who did not.
