New research from the Centers for Disease Contol has found that a large number of contact lens solutions do not protect against Acanthamoeba keratitis or A. Keratitis. Only two contact lens solutions out of a dozen tested proved to be effective against A. Keratitis organisms. Those two solutions contained hydrogen peroxide. Sanitation habits have also been implicated in the development of A. Keratitis.
Some wearers of contact lenses may be tempted to save money by taking hygienic shortcuts when it comes to keeping their contacts clean. Instead of buying cleansing solution for their lenses, they may decide to rinse them with plain water or even attempt to use a homemade solution which is not properly preserved nor sterilized.. While money may be saved by taking this laid back approach to cleaning the contacts lenses, the possible harmful consequences of vision loss far outweigh the financial benefits of adopting a do-it-yourself mentality. The problem with homemade solutions is that these will lack anti-bacterial efficacy – harmful bacteria will continue run rampant on contact lenses and can cause serious medical complications if the eyes become infected.
A corneal ulcer is an open sore or non-penetrating erosion in the transparent area at the front of the eyeball – the cornea – and is associated with infections caused by bacteria. This is exactly the kind of bacteria that freely grows on contact lenses when homemade solutions are substituted for commercial cleansing solutions. Corneal ulcers can also be precipitated by wearing soft contact lenses overnight.
Those who attempt to use their own homemade cleaning solutions also run the risk of contracting Acanthamoeba keratitis, Acanthamoeba is a water-borne, microscopic parasite that can wreck havoc in the form of an infection when it invades the cornea. While using homemade solutions are often the cause, swimming in lakes and swimming pools while wearing contacts can also trigger the condition.
The symptoms that accompany this infection are intense pain and redness, and those afflicted with the infection are often hospitalized. If corneal scarring results, a cornea transplant may be necessary. Treatment and therapy may last a year or more, and sometimes severe vision lost can be the outcome of a bout with Acanthamoeba keratitis.
Here are a few tips to help prevent complications from A. Keratitis:
- Choose a contact lens solution that contains hydrogen peroxide.
- Avoid the use of homemade cleansing solutions
- Make sure you use commercial cleansing solutions
- Make sure you clean the cases for your contacts; discard and replace the cases every three or four months
- Be aware that sometimes wearing soft contact lenses overnight can cause infections for some people
- Be aware of all factors that may cause infections and medical complications, such as wearing contacts while swimming in lakes, pools or the ocean
Don’t allow destructive bacterial to build up on your contact lenses and in your cases. Eye-damaging conditions like A keratitis can be held at bay by following a simple set of hygeinic procedures that will help to ensure that your eyes stay healhly and infection free.
