Corneal Refractive Therapy (CRT)

NON-Surgical Vision Correction, WHILE YOU SLEEP!

Paragon CRTCorneal Refractive Therapy (CRT) is a non-surgical way to correct your vision while you sleep. These are special contact lenses that gently reshape the front surface of your cornea while you wear them overnight. Once the process is complete, your need for glasses or contact lenses during the day is eliminated.

This is a great option for anyone who is tired of glasses and/or daytime contact lens wear.

  • If you have ever considered Lasik surgery but have been told you are not a good candidate, are still too young, or if you are just apprehensive about spending close to $4000 and having surgery on your eyes then this may be a good choice for you.
  • Patients that can no longer stand wearing contacts during the day because they always dry out.
  • Children that are very active in sports are also great candidates.
  •  CRT is the most effective therapy, that has been proven in several studies, to slow or even stop the progression of myopia (nearsightedness) in children!
  • CRT is FDA approved for patients of all ages with low to moderate amounts of nearsightedness with or without mild corneal astigmatism.

Frequently Asked Questions about Corneal Refractive Therapy

[accordion]
[acc_item title=”What is Paragon CRT®?”]Paragon CRT is a specially designed oxygen permeable therapeutic contact lens used in Corneal Refractive Therapy.[/acc_item]
[acc_item title=”What is Corneal Refractive Therapy?”]Corneal Refractive Therapy is a sophisticated non-surgical process that temporarily re-shapes the cornea while you sleep. You remove the lenses when you awake and are able to go throughout the day without any other vision correction.[/acc_item]
[acc_item title=”How new is Paragon CRT?”]The idea of contact lens corneal reshaping 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 to produce a therapeutic contact lens design that is like no other. This has allowed Paragon CRT to become the one corneal reshaping modality that truly stands out and the first to earn FDA approval for nighttime Corneal Refractive Therapy.[/acc_item]

[acc_item title=”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.[/acc_item]

[acc_item title=”Can everyone wear Paragon CRT?”]Paragon CRT treats nearsightedness (myopia up to –4.50 diopters) with or without minor corneal astigmatism (up to –1.25 diopters). And because there are no age restrictions on Paragon CRT, it may be the perfect option for any member of the family including active adolescents. The doctor will provide more information about Paragon CRT to see if it is right for you.

Paragon CRT therapeutic contact lenses are not yet available in bifocal prescriptions for presbyopia (which requires reading glasses or bifocals). At the doctor’s discretion 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 Paragon CRT, at any age, can only be made after a thorough eye exam and the recommendations of an eye care professional. At this time, hyperopia (farsightedness) is not correctable with Paragon CRT.[/acc_item]

[acc_item title=”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.[/acc_item]
[acc_item title=”What do I do to see adequately in the period of time between when I start Corneal Refractive Therapy with Paragon CRT and when I achieve full treatment?”]It’s important to understand that for a time after you have begun treatment, but before sufficient treatment is realized, your old glasses or contacts will no longer be the appropriate prescription. It may involve re-insertion of your Paragon CRT lenses for part of the day or some use of temporary soft lenses in different prescriptions. The doctor will discuss your options for visual correction during that period of time.[/acc_item]
[acc_item title=”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.[/acc_item]
[acc_item title=”Can I see with my Paragon CRT lenses in?”]Yes. One of the great features of the Paragon CRT lens is that if you get up in the middle of the night, you will be able to see perfectly. You will enjoy great vision with your Paragon CRT lenses on or off.[/acc_item]
[acc_item title=”How often will I have to replace my Paragon CRT lenses?”]Generally speaking, the Paragon CRT lenses will have to be replaced every one to two years. However, depending on factors such as protein buildup, how well the lenses are taken care of, etc., the lenses may have to be replaced more or less frequently.[/acc_item]
[acc_item title=”How do I care for my Paragon CRT lenses?”]Your lenses should be chemically disinfected after every use (not heat). We will instruct you about which care system is best for you. Paragon Vision Sciences exclusively recommends Unique-ph® Multi-purpose solution.[/acc_item]
[acc_item title=”How much does Corneal Refractive Therapy with Paragon CRT cost?”]Our initial cost for Corneal Refractive Therapy with Paragon CRT is $1490. This includes:
1. A thorough eye examination to determine your prescription and to ensure ocular health.
2. Corneal mapping to determine your individual ocular measurements.
3. One set of CRT lenses to use for treatment once the final lens parameters have been determined.
4. Six months of follow-up visits to ensure the lenses are working properly and the eyes are healthy.
5. Discounts on a second spare pair of CRT lenses or if one is broken or lost for the first 6 months.

Be sure to ask our staff about using Care Credit to assist with any costs and we will be happy to review it with you. Payments can be as low as $125 per month for 1 year with 0% interest if you qualify.  Also, for subsequent years, the cost of Paragon CRT is about the same as regular contact lenses or glasses.[/acc_item]
[acc_item title=”What if I decide CRT isn’t right for me after I’ve started the therapy?  Are there any refunds?”]Yes!  We understand this is a substantial investment for many patients and we want you to have some peace of mind when making the decision. If you decide to discontinue the therapy within 14 days of your initial start date we will refund you $1000.  If you decide to discontinue the therapy within 60 days of your initial start date we will refund you $500.  All refunds require the return of all undamaged CRT lenses that have been dispensed.  No refunds will be issued after 60 days of the initial fit date.  All refunds will be minus any promotional discounts already given.
[/acc_item]
[acc_item title=”Is Corneal Refractive Therapy painful?”]The therapy is not painful. Initially, you may have a slight awareness of the therapeutic lens. You will not feel the lenses when you sleep and there is no sense of physical corneal change,  just visual improvement when the lenses are removed.[/acc_item]
[acc_item title=”Is Corneal Refractive Therapy or Paragon CRT FDA approved?”]Paragon CRT is the first therapeutic lens design approved by the FDA for overnight contact lens wear 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.[/acc_item]
[acc_item title=”What is the difference between Corneal Refractive Therapy and Paragon CRT?”]Corneal Refractive Therapy is the process of using a therapeutic contact lens to reduce myopia by reshaping the corneal surface while you sleep. Paragon CRT is the product used for this therapy.[/acc_item]
[acc_item title=”Are there age restrictions for Corneal Refractive Therapy with Paragon CRT?”]No. The FDA placed no age restrictions on candidates for Corneal Refractive Therapy with Paragon CRT. Paragon 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.

Those who are older and presbyopic (requiring reading glasses or bifocals) may still be candidates for Paragon CRT. They may correct their distance vision with Paragon CRT and wear near vision glasses for close work. At the doctor’s discretion you may be fitted in a monovision mode (one eye corrected for near vision and one corrected for distance vision).

Visual requirements due to age or activities can only be made after a thorough eye exam and recommendations of a Paragon CRT certified eye care professional.[/acc_item]
[acc_item title=”Are the Paragon CRT lenses difficult to insert or remove?”]These lenses are generally no more difficult to insert or remove than any other similar contact lens modality. You may want to instill comfort or rewetting drops prior to insertion of the lenses and immediately upon waking. The lenses must move freely prior to removal. If you have difficulty removing the Paragon CRT lens, there are lens removal aids available to assist this process.
[/acc_item]
[acc_item title=”If I discontinue CRT, will my vision to return to normal?”]There are no recorded permanent corneal changes post-treatment. Generally, the more myopia being reduced, the longer it will take for the corneal curvature to return to normal. For instance, if your pretreated correction was – 4.50D, it would take a few days longer to return to normal than if the pretreated correction was -1.50D.[/acc_item]
[acc_item title=”My driver’s license is marked that I need corrective lenses to operate a motor vehicle. What do I do about that?”]Your eye care professional will supply you with a document that states you are participating in a visual therapy program that eliminates the need for corrective lenses while operating a motor vehicle. The document should have an expiration date for this treatment 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.[/acc_item]
[acc_item title=”What happens if I lose or damage a lens?”]Corneal Refractive Therapy is different than wearing regular contact lenses. If you discontinue wear for one night, your vision may be impaired the next day. Previously worn glasses or contact lenses may not help. Immediate replacement is necessary! Having a spare pair of lenses is strongly recommended.[/acc_item]
[acc_item title=”Does insurance cover Corneal Refractive Therapy?”]This is an elective procedure and is NOT covered by insurance programs. If regular contact lenses are covered under your vision care plan, then the Corneal Refractive Therapy lenses may be partially covered. You should check with your benefits plan administrator.[/acc_item]
[acc_item title=”I suffer from “dry” eyes. Am I a candidate for Corneal Refractive Therapy?”]Only your eye care professional can determine if you are a CRT candidate. Many patients with slightly dry eyes do well with Paragon 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.
[/acc_item]
[acc_item title=”I used to wear contact lenses, but stopped due to discomfort. Am I a candidate for Corneal Refractive Therapy?”]Paragon CRT lenses are worn at night while you are sleeping. This greatly reduces any discomfort normally experienced while wearing contact lenses during the day.[/acc_item]
