Paragon CRT is a specially designed therapeutic contact lens that gently and temporarily reshapes the cornea while you sleep. Through intense research and clinical testing, Paragon CRT has proven both safe and effective for patients of all ages when worn during sleeping hours, earning this therapy FDA approval for nighttime use. The result for you is great vision 24 hours a day – without the lenses during waking hours and while they’re in at night – with correction of myopia (nearsightedness) and myopia with astigmatism.

Frequently Asked Questions:
What is Paragon CRT?
Paragon CRT is a specially designed oxygen permeable therapeutic contact lens used in Corneal Refractive Therapy (CRT).

What is CRT?
Corneal Refractive Therapy is a technologically advanced, nonsurgical process, which reshapes the cornea while you sleep. You remove the lenses when you awake and are able to go throughout the day without any other correction.

Is Paragon CRT new?
While contact lens corneal reshaping is not a new concept, Paragon CRT is the one corneal reshaping modality with proven safety and efficacy and the first to earn FDA approval for nighttime Corneal Refractive Therapy.

Is CRT permanent?
No. It’s temporary. If you stop wearing the lenses your vision will return to its original state in as little as 72 hours.

Can everyone wear Paragon CRT?
Not everyone can wear Paragon CRT. This lens is designed for individuals for low to moderate myopia (nearightedness up to -6.00diopters) with or without astigmatism (up to -1.75 diopters). There are no age restrictions for Paragon CRT, which makes it a great option for everyone in the family. However, since there are variations in patient physiology and visual needs, the decision for CRT, at any age, can only be made after a thorough exam and the recommendations of the eye care professional.

How long does it take to reach and maintain good vision throughout waking hours?
Most patients have rapid improvement in the first few days of treatment and achieve nearly their optimum vision in 7 to 14 days.

What do I do to see adequately in the period of time between when I start CRT and when I achieve full treatment?
During this transitional period, you may insert Paragon CRT lenses for part of the day or use temporary soft contact lenses. Your eye care practitioner will discuss your best option with you.

Are there any risks involved with wearing Paragon CRT?
There is a small risk involved when any contact lens is worn. There were no serious adverse events observed in the Paragon CRT FDA clinical study.

Can I see with my Paragon CRT lenses in?
Yes. One of the great features of the Paragon CRT lens is you will be able to see clearly with your lenses on and off!

How often will I have to replace my Paragon CRT lenses?
Generally speaking the Paragon CRT lenses will have to be replaced yearly.

How do I care for my Paragon CRT lenses?
