Corneal Refractive Therapy: All Day Freedom from Glasses and Contacts

Correct your vision while you sleep. Wake up seeing clearly.

Good-bye dry eye!

Contact lens wearers often develop dry eye symptoms – particularly in Colorado. Corneal Refractive Therapy (CRT) lenses are worn only while sleeping, eliminating the dryness and discomfort of daytime contacts and giving you freedom and comfort all day long.

In fact, many successful CRT patients were previous soft lens wearers and, sometimes, CRT is a better solution than LASIK surgery.

CRT works while you sleep

Paragon CRT Lenses

At Highline Vision Center, we trust Paragon CRT lenses. Paragon CRT is a specially designed therapeutic contact lens that gently and temporarily reshape the cornea while you sleep. Paragon CRT has been FDA approved since 2002 and has been found both safe and effective for patients of all ages when worn during sleeping hours.

CRT Frequently Asked Questions

What is Corneal Refractive Therapy? Corneal Refractive Therapy, AKA Orthokeratology, is the design and fitting of special gas permeable contacts that gently reshape the front surface of the eye (cornea) so you can see clearly even after you remove the lenses.

What is Paragon CRT®? Paragon CRT is a specially designed, oxygen permeable, therapeutic contact lens used in Corneal Refractive Therapy (also called Corneal Reshaping Therapy).

What does current research say about CRT? Treatment results should equal the vision correction provided by traditional glasses or contacts. 1Studies suggest the possibility that wearing lenses such as CRT helps to slow or even stop the progression of nearsightedness.

How long does it take for CRT to start working? Most patients see dramatic improvement in the first few days, with complete vision correction within 1-2 weeks.

Is CRT safe? Yes. Part of the safety profile lies in the fact that, if you stop wearing CRT lenses, your vision will return to its previous levels.

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

How much does CRT cost? CRT starts around $1500 and your exact cost will be determined at your free consultation. Initially, CRT is more expensive than soft contact lenses, however, subsequent years the cost is comprable.

Ultimate Control

No more torn lenses. No more broken frames. No more discomfort from dry eyes. CRT puts an end to these hassles. You just wear the CRT lenses while you sleep and remove them when you wake up. It’s that simple. And because you can stop the therapy at any time without permanent change to your eyes, you have ultimate control and flexibility in your vision correction.

Finally! A solution that keeps up with your active lifestyle. 

Corneal Refractive Therapy (CRT) corrects your vision while you sleep using a specially designed contact lens. The lens reshapes your cornea temporarily. There is no permanent change to your eye’s physiology – which is important because the eyes of children and teens are still maturing.

At Highline, we have been using FDA-approved lenses for CRT treatment for over 10 years. Our patients wear these lenses at night and remove them in the morning. The result is clear vision all day whether it’s in the classroom or in the game!
