According to CDC scientists, ReNu with MoistureLoc contact lens solution was linked to an outbreak of Fusarium Keratitis – a fungal eye infection – as a result of a chemical reaction within the solution. Scientists also say the chemical reaction did not take place during storage or manufacturing, but most likely happened at users’ homes.

The researchers added that poor contact lens wearer hygiene and compliance was also a factor. Their study showed that users of ReNu with MoistureLoc solution were 20 times more likely to develop the infection than users of other solutions.

Bausch & Lomb’s ReNu with MoistureLoc solution was withdrawn from the market in May this year.

The scientists think there is something about the chemical make-up of the solution that allows the fungus to grow and cause infection. Even though they do not yet know how this happens, it is important that people who wear contact lenses do not use MoistureLoc.

Earlier on this year several patients with eye infection were reported in Hong Kong and Singapore, many of whom had been using Bausch & Lomb ReNu brands for cleaning their contact lenses. Then similar reports started coming in among contact lens users in the USA.

Scientists are trying to find out what the exact mechanism of the infection is. So far, all they have found out is that there may be several different sources.

What is Fusarium Keratitis?

It is a severe infection of the cornea. Fusarium is a rapidly growing fungus, some of which can cause eye infections, leading to damage of the cornea. Keratitis is inflammation of the cornea. The cornea is the clear membrane that covers the iris and pupil.

Fusarium Keratitis Symptoms May Include

— Eye discharge
— Pain in the eye
— Sensitivity to light
— Tearing
— Unusual eye redness

If treated early, fungal keratitis is almost always completely curable. However, a serious infection can cause glaucoma, permanent scarring, cornea ulceration and blindness.

Fusarium keratitis is not human transmissible – one human cannot catch it from another human.
