What is Paragon CRT®?
Paragon CRT is a specially designed oxygen permeable therapeutic
contact lens used in Corneal Refractive Therapy. Corneal Refractive
Therapy is a sophisticated, non-surgical 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 Corneal Refractive Therapy Permanent?
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. [ TOP ]
Can everyone wear Paragon CRT®?
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. [ TOP

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. [ TOP

How long does it take to reach good vision?
Most patients have rapid improvement in the first few days of
treatment and achieve nearly their optimum vision in 10 to 14 days.

Are there any risks involved with wearing Paragon
CRT?
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. [ TOP ]
Can I see with my Paragon CRT lenses in?
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. [ TOP ]
How often will I have to replace my Paragon CRT
lenses?
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. [ TOP ]
What is the cost for Paragon CRT lenses?
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. [ TOP ]
Is Corneal Refractive Therapy FDA approved?
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. [

Will I still need a "Visual
Restriction" on my driver’s license?
We will supply you with a document that states you are participating
in a visual therapy program that eliminates the need for corrective
lenses during working hours. The document should have an expiration
date and you should have your driver’s license updated with a new
vision screening through your local DMV office to reflect this
change, before the expiration date. [ TOP ]
I suffer from “Dry Eyes", Can I have CRT?
Probably, but we can only determine this through a thorough eye
examination. Many patients with dry eyes do well with CRT. Since you
are wearing the lenses only while sleeping, the closed eye state
minimizes evaporative loss of tears and can give dry-eye patients
suitable vision without compromising the ocular surface. [
