is Paragon CRT®?
Paragon CRT is a unique oxygen permeable therapeutic contact lens designed
to temporarily correct myopia (nearsightedness and moderate levels
of astigmatism) by gently reshaping the cornea during sleep. Patients
remove them in the morning and go throughout the day without any other
you refer to Paragon CRT as Corneal Refractive Therapy, isn’t
it just another name for Orthokeratology?
Paragon’s approval from the FDA for overnight corneal reshaping is
for Corneal Refractive Therapy. Historically, Ortho-K involved using
a series of lenses over a period of months to achieve the desired effect.
Corneal Refractive Therapy with Paragon CRT is primarily a single lens
therapy over a period of 5-14 days. Although corneal reshaping with
contact lenses is not a new concept, previous corneal reshaping designs
were only as successful as technology allowed. Paragon Vision Sciences
has taken the recent advancements in computerized corneal mapping,
computerized manufacturing and oxygen permeable contact lens materials
and produced a therapeutic lens that is unique in its design and application.
Paragon also undertook the most extensive overnight study ever attempted
in this modality to demonstrate its safety and efficacy. As a result,
Paragon CRT stands alone with supportive science and new technology.
How many diopters of myopia and astigmatism can be treated with Paragon
The FDA approved Paragon CRT for up to –6.00 diopters of myopia and
up to –1.75 diopters of astigmatism. Generally, the easiest to fit
cases are under –4.50 diopters, but myopes up to –6.00 diopters have
experienced great success.
Is there any age restriction?
No. The FDA has not put an age restriction on Corneal Refractive Therapy.
Do I need to have a topographer to fit Paragon CRT?
Although a topographer is not required to fit the lens, Paragon strongly
urges the use of the topography, which can improve patient management,
establish baseline data, and make patient follow-up and troubleshooting
easier and more efficient. In fact, Paragon exclusively recommends
the Humphreys ATLAS™ and has developed software for use with
this topographer. You may also wish to take advantage of the Platinum
Advantage Program that offers a special leasing package combining
the Atlas, software and your complete Paragon CRT system.
do I have to do to get involved with Paragon CRT?
The FDA requires that all practitioners who wish to fit and dispense
Paragon CRT be trained, tested and certified by Paragon Vision Sciences.
You may become certified by logging on to the restricted practitioner
section of the website, reviewing all training materials and, following
the instructions provided, take the Paragon CRT certification test.
You may also request a training CD-ROM from this website or by calling
Paragon at 800-528-8279 x 7610.
Once you have been certified, you can purchase the Diagnostic Dispensing
System that is required so that you can prescribe and dispense Paragon
CRT. If you are in a practice that already has a Diagnostic Dispensing
System, you need not purchase a second system. With the Diagnostic
Dispensing System you will also receive a complete Practice Management
Kit that contains all the tools needed to smoothly transition and market
Paragon CRT within your practice.
Do I need a fitting set to fit Paragon CRT?
Yes, but the Paragon CRT Diagnostic Dispensing System is more than
a fitting set. This 100 lens set allows you to dispense an estimated
four out of five qualified patients on their first visit. If the
first lens needs adjustments during the fitting process, the next
lens is normally right in your dispensing system. This saves you
chair time and patient visits, provides more immediate patient satisfaction
and helps control your cost of goods. However, in order to receive
the Diagnostic Dispensing System you need to be trained, tested and
certified to fit Paragon CRT by Paragon Vision Sciences, Inc.
What do the Diagnostic Dispensing System and lenses cost?
