Injured consumers worldwide reported loss of vision due to the product: one man in Brisbane, Australia claims that he lost vision in his right eye a few months after using the contact lens solution and filed a lawsuit against AMO in Orange County, California.
In July, 2006 a man in North Carolina began to suffer symptoms of pain, light sensitivity, tearing, and vision impairment in his left eye after using AMO. In August 2006, he was diagnosed with Acanthamoeba keratitis and by July 2007, all this time in severe pain, his doctor ordered an emergency corneal transplant.

In June, 2007 a Texas resident filed a lawsuit against AMO alleging that she suffered permanent vision loss due to Acanthamoeba keratitis, from use of AMO's Complete MoisturePlus Multi Purpose contact lens solution. She began to suffer symptoms of light sensitivity, tearing, and redness in 2004, but her doctors were unable to diagnose her condition. By the end of 2004, she lost the vision in her left eye and in January 2005, she was finally diagnosed with Acanthamoeba keratitis. The woman waited nine months for a corneal transplant--her vision is still impaired.
There are currently more than 48 separate lawsuits involving over 80 individual plaintiffs pending against AMO, including several class actions. Lawyers predict that more cases will be filed as medical records of potential claimants are evaluated.
AMO Recalled
The recall followed a warning from the US Centre for Disease Control and Prevention (CDC) that the risk of developing the rare eye infection was at least seven times greater for those using the product. A spokesman for CDC reportedly called the continued use of the product by those unaware of the risk "a real tragedy."
By July 31, the FDA announced on its website that the recall had been reclassified from "voluntary" to "Class 1," which FDA reserves for cases where product use is associated with the "reasonable probability" of "serious adverse health consequences or death." Although the FDA alerted health care workers and soft contact lens customers about the recall, lawsuits state that AMO failed to adequately notify consumers and retailers of the recall.
Complaints allege that AMO's contact lens solution was not effective in disinfecting contact lenses; it was inferior to other multipurpose solutions available on the market; and that AMO's own data demonstrated the product's lack of effectiveness in preventing the growth of protozoa microorganisms, including acanthamoeba.
