No. It’s temporary. If you stop wearing the lenses regularly while you sleep, your vision will return to its original state in as little as 72 hours.

Not everyone can wear Paragon CRT. This lens is designed for individuals with low to moderate myopia (nearsightedness) with or without astigmatism (up to –1.75 diopters). Paragon CRT therapeutic lenses are not yet available in bifocal prescriptions for presbyopia (which requires reading glasses or bifocals). Depending on your needs, you may be fitted in a monovision mode (one eye corrected for near vision and one corrected for distance vision). You might still need reading glasses. 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 eye exam. At this time, hyperopia (farsightedness) is not correctable with CRT.

The FDA placed no age restrictions on candidates for Corneal Refractive Therapy with Paragon CRT. CRT is being successfully performed on children 12 years old and younger. It can be a great option for children and teens that are active in sports activities or any other extra curricular activities.

Most patients have rapid improvement in the first few days of treatment and achieve nearly their optimum vision in 10 to 14 days.

There is a small risk involved when any contact lens is worn. It is not expected that the Paragon CRT lenses for contact lens Corneal Refractive Therapy will provide a risk that is greater than other contact lenses. There were no serious adverse events reported in the Paragon CRT FDA clinical study.

Yes. One of the great features of the Paragon CRT lens is that if you have to get up in the middle of the night, you will be able to see where you are going. Or, if during the initial treatment phase, you find you need some form of vision correction, you can put in your Paragon CRT lenses and see clearly.

Generally speaking the Paragon CRT lenses will have to be replaced once a year. However, depending on factors such as protein build-up, how well the lenses are taken care of, etc., the lenses may have to be replaced more frequently.

The cost of CRT lenses are less than any surgical procedure and a little more than the average person spends on yearly expenses related to contact lenses or glasses.

Paragon CRT is the first therapeutic lens design approved by the FDA for overnight contact lens Corneal Refractive Therapy for the temporary reduction of myopia. Paragon Vision Sciences, the manufacturer of Paragon CRT, received the final written approval on June 13, 2002. The issuance of this approval is the culmination of the most extensive clinical study to date to establish the safety and efficacy of contact lens corneal reshaping in overnight use.
