Possible Problems With Contact Lenses: Corneal Infections

One of the most prevelant of healthcare problems experienced by people everywhere is infections.  Tens of thousands of peopel suffer serious consequences as the result of infections of different types each and every year.

The Hazards of Contact Lenses

Although contact lenses have a lot of aesthetic appeal and are sometimes more convenient for eyeglass wearers, they can also cause a number of eye health problems. Without proper fitting, care, and monitoring, they can become hazards instead of a convenience.

Though Rare, Corneal Infestions are Serious

While corneal infections are rare, they are potentially serious consequences of contact lens wear. Microbial keratitis (corneal infection) could lead to pain, discomfort, and even permanent vision loss. Some advanced cases require corneal transplants. The leading cause of corneal infections is a common fungus called fusarium.

The Outbreak of Corneal Fungus

In a recent outbreak of corneal fungus infections (June 2006), it was found that 94 percent of the patients wore soft contact lenses. While a common lens conditioning product was also considered as a contributing factor, it’s also known that soft contact lenses reduce the amount of oxygen that can reach the surface of the eye. These hypoxic conditions can contribute to corneal ulceration, which makes hygiene more important.

Avoiding Microbial Keratitis

If you are considering soft lenses, or have them already, there are things you can do to avoid microbial keratitis. First, don’t sleep in your contacts. If you have extended or continuous wear contacts for comfort, consider taking them out every night to reduce your chance of corneal infections. Also, make sure you wash your hands before placing or removing your contact lenses. Hygiene is the most important tool you have.

Check for Allergies

Make sure you aren’t allergic to your solutions or other lens products. If you suspect you may be reacting to them, call your eye care practitioner immediately. Don’t change brands without speaking to your physician-some products and lenses are incompatible, and you may be allergic to new solutions. Also, go ahead and rub your lenses, even if the solution says you don’t have to. This will loosen the bacteria and expose it to the disinfectant.

Use Your Contact Lenses as Prescribed

If you have disposable contact lenses, throw them away on schedule. Don’t keep them just because you think they are clear enough to continue wearing. If you’re in doubt as to your replacement schedule, call your eye doctor. Even if you don’t wear disposables, make sure you get your regular eye exam and new contact lenses on schedule.

When Not to Wear Your Contact Lenses

Also, if you are already having problems or your eyes are simply red and irritated from another cause, don’t wear your lenses-they will only make the scratching and irritation worse, and could cause an infection.
