corneal refractive therapy

You just woke up from a restful night's sleep. But as you start your day, you notice something different. You can see without your glasses or contacts. And you haven't had surgery. Well, you're not dreaming. You're just experiencing Corneal Refractive Therapy with new Paragon CRT—nighttime vision correction that gives you freedom from glasses and contacts all day without refractive surgery.

Proven Result

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 been 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.

crt questions

What is Paragon CRT?

Paragon CRT is an oxygen permeable contact lens used therapeutically for vision correction in Corneal Refractive Therapy (CRT).

What is CRT?
Corneal Refractive Therapy is a technologically advanced, non-invasive, non-surgical process, which reshapes the cornea while you sleep. You remove the Paragon CRT contact lenses when you awake and are able to see throughout the day without any other correction.

Is CRT Permanent?
No. The effects of CRT are temporary. Your vision will return to its previous level in as little as three days if you discontinue wearing the lenses.

Is Paragon CRT new?
While reshaping the cornea by means of a contact lens is not new, corneal reshaping with Paragon CRT has a proven record of safety and effectiveness, and it is the first corneal reshaping method to gain FDA approval for overnight Corneal Refractive Therapy.

Can everyone wear Paragon CRT?
No, Paragon CRT is not designed for everyone. The lens is indicated for people with low to moderate degrees of myopia (nearsightedness of –6.00 diopters or less), with or without astigmatism (maximum –1.75 diopters). There are no age restrictions for Paragon CRT, which makes it a great option for everyone in the family. However, each patient’s physiology and visual needs are different, so before making the decision to use CRT, a complete eye exam and consultation with an eye care professional is necessary.

Are there any risks involved with wearing Paragon CRT?
Wearing any type of contact lens involves some minimal risks. In the clinical study conducted by the FDA on the Paragon CRT lens, however, no serious adverse events were recorded.

Can I see with my Paragon CRT lenses in?
Yes. That’s one of the advantages of the Paragon CRT lens. You will be able to see clearly with your lenses on and off!

How do I care for my Paragon CRT lenses?
You will need to disinfect your lens following each use. Your eye care professional will advise you on the lens care system best suited to you.
