Paragon Corneal Refractive Therapy (CRT)

Paragon corneal refractive therapy (CRT) is a specially designed therapeutic contact lens worn during sleeping hours to reshape the cornea without permanently altering its physiology - which is important, as the eyes of children and teens are still maturing. Your child simply wears the lenses at night and takes them out in the morning, the result is clear vision the whole day - in class, at practice and while doing homework.


Is CRT new?

The idea of corneal reshaping is not a new one. But, Paragon CRT is the first therapeutic contact lens proven to work and proven safe for overnight wear.

Is Paragon CRT permanent?

No. If you stop wearing the lenses, your vision will return to how it was.

How long does it take to start working?

Most patients see dramatic improvement in the first few days, with complete vision correction in one to two weeks.

Can I see while wearing my Paragon CRT?

Absolutely. You can see with the lenses on or off. So if you have to get up at night, no problem.

How often should I replace my Paragon CRT lenses?

About once a year.

How do I take care of them?

You should clean them after every use. Your eye doctor can tell you which system is best for you.
