CRT and Your Eyes


Meadows Eye CareDo you have poor vision and you’ve heard about corneal reshaping treatment, or CRT? Maybe you’re trying to figure out if this treatment is right for you or your children. While the treatment can have some long-term positive effects, the truth is that there are also dangers. If you need to make a decision about CRT, here’s what you need to know.

CRT is available for people who suffer from myopia, or nearsightedness. It involves sleeping overnight in a special pair of contact lenses. These work to reshape the cornea. You take the lenses out in the morning and have normal, perfect vision all day long. If you wear the lenses every night, they can even slow the progression of myopia. In general, this treatment is mostly available for children. They’re the ones whose eyes are still changing.

This treatment has been available since 2002. A pair of CRT lenses usually costs between $800 and $2,000, and many insurance plans do not cover it. If money is a concern for you, then this may not be the right treatment. However, if you can convince your insurance company to pay, or you have the ability to get the lenses, they can help you see better all day long.

One of the main dangers of CRT is getting an infection. Part of the problem is that the lenses are usually prescribed to children and teenagers, who are not always the best at cleaning the lenses and practicing proper hygiene with them.  This can allow all sorts of foreign substances to get on the lenses. These may then be introduced to the eye.

Infection is a particular problem of CRT lenses because sleeping with lenses in means that the infection has a longer unmitigated time to transfer to the eye. While infections are possible from wearing any contact lenses, it’s the wearing them overnight part that makes these particularly dangerous

More recently, CRT lenses have been made out of materials. Providers have also been required to take training classes and pass a test before prescribing the lenses. This helps ensure that patients are given the correct lenses for their eyes and that they are also given the correct instructions for using those lenses properly.

The relative danger from CRT lenses is actually pretty small. Only a few children and teenagers have suffered from eye infections. However, you will need to decide for yourself if the benefits of CRT outweigh these risks. In extreme cases, patients have required corneal transplants to recover from the infections they’ve gotten from these lenses. This can change a person’s life forever!

If you decide to go with CRT lenses, make sure you get them from a reputable doctor. Make sure you understand all of the things that you need to do to keep your lenses clean and to use them properly and hygienically. Make sure that you follow these procedures religiously, so your lenses never have a chance to transport bacteria, viruses, or fungal infections to your eye.
Used properly, CRT lenses can enhance vision and change a person’s life. As long as you take the proper precautions, they can be a great investment and a good decision for many years.
