Are contact lens solutions the cause of the infections?
No one is sure yet, but the investigation is looking into possible links between solutions and the infections. Consumers are being told not to use Bausch & Lomb ReNu with MoistureLoc, which the CDC says was used by people in a majority of the confirmed cases of fungal keratitis. Other cases, in smaller but still significant numbers, involved Bausch & Lomb ReNu MultiPlus solution. Contact lens solutions manufactured by Alcon and AMO were also mentioned, but in just a handful of the cases. There is no recommendation at this time to stop using any specific products, other than ReNu with MoistureLoc. There is no confirmed increased risk of infection by using contact lens solution or wearing contact lenses.
