Renu MoistureLoc Permanently Recalled

The American Academy of Ophthalmology reports on the permanent recall of Renu's MoistureLoc brand contact lens solution, following a study that found a positive correlation between MoistureLoc and Fusarium keratitis, a fungal infection of the cornea. No other Renu products or similar competing brands were implicated.

In a letter to the Academy, Bausch & Lomb specifically mentions alexidine, a disinfecting agent added to MoistureLoc. MultiPlus and Multi-Purpose do not include alexidine.
The letter states that alexidine is safe and effective, but under certain extreme conditions - such as the solution is allowed to evaporate, the solution is not regularly replaced in the lens case, when the bottle is kept open in between uses or when the case is not cleaned properly or changed regularly - "the concentration of polymers included in the formula to enhance comfort may make the solution more likely to be contaminated with Fusarium in the environment."
