Orthokeratology with Paragon CRT® Contact Lenses is a sophisticated, non-surgical process. By wearing Paragon CRT® Contact Lenses while you sleep, the lenses gently reshape the cornea. You remove the Paragon CRT® Contact Lens when you awake and are able to go throughout the day without any other correction to your vision needed.
You may be given a temporary Paragon CRT® Contact Lens during your initial treatment period. Once your initial treatment period is over, your eye care practitioner will take back these lenses and give you a new Paragon CRT® Contact Lens that will have a light green tint along with a laser mark of numbers. The green lens will become your permanent Paragon CRT® Contact Lenses that you’ll sleep in each night.
Paragon CRT® Contact Lenses have a very small laser mark on the lens surface that consists of a series of numbers (and in some cases, letters) to assure you and your eye care practitioner that you have original Paragon CRT® Contact Lenses. The laser mark will not interfere with the orthokeratology process. If your lenses do not have a laser mark on the lens surface, you’re not wearing the worldwide leading orthokeratology product, Paragon CRT® Contact Lenses, and you should consult your eye care practitioner.
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.
Most patients have accelerated improvement in the first few days of treatment and achieve nearly their optimum vision in 10 to 14 days.
It’s important to understand that during the short treatment process, old glasses or daytime contacts will no longer be the appropriate prescription. Managing your vision during the treatment process may involve reinsertion of the Paragon CRT® Contact Lenses for part of the day, or your eye care professional may choose to use temporary soft disposable lenses. Your eye care professional will discuss the options for visual correction during this temporary period of time.
When any contact lens is worn, there is a small risk involved. However, it is not expected that Paragon CRT® Contact Lenses will provide a risk that is greater than other contact lenses that are worn while sleeping. During the Paragon CRT® Contact Lenses FDA Clinical Study, there were no serious adverse events reported. Please refer to the Package Insert for more information.
Yes! One of the great features of the Paragon CRT® Contact Lenses is that if you get up in the middle of the night, you should be able to see. You should enjoy great vision with your Paragon CRT® Contact Lenses 24 hours a day, on and off!
Generally speaking the Paragon CRT® Contact Lenses will have to be replaced once a year. However, depending on factors such as protein build-up, lens care, etc., the lenses may have to be replaced more frequently.
Your lenses should be chemically disinfected after every use (without heat). Your eye care practitioner will instruct you as to which care system is best for you.
The cost of orthokeratology with Paragon CRT® Contact Lenses varies based on the eye care provider and visual requirements of the patient. It is recommended that you speak with your eye care professional about the cost for the first and subsequent years.
No, it is not painful. Initially, you may have a slight awareness of the Paragon CRT® Contact Lens in your eye. 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. In the FDA study, 96% found the comfort level acceptable.
Orthokeratology is the process of using a therapeutic contact lens to reduce myopia by reshaping the corneal surface while you sleep. Paragon CRT® Contact Lenses is the leading product used for this therapy.
Yes! Paragon CRT® Contact Lenses are the first therapeutic lens design approved by the FDA for overnight orthokeratology for the temporary reduction of myopia. Paragon Vision Sciences, the manufacturer of Paragon CRT® Contact Lenses, received final FDA approval on June 13, 2002, which was the culmination of the most extensive clinical study of overnight orthokeratology to-date.
No, the FDA placed no age restrictions on candidates for orthokeratology with Paragon CRT® Contact Lenses. It’s a great option for children and teens that are involved in sports or other extra-curricular activities. Adults also enjoy the freedom of Paragon CRT® Contact Lenses and even those that may be presbyopic (requiring reading glasses or bifocals), may still be great candidates with monovision and Paragon CRT® Contact Lenses.
After a thorough eye exam, and at your certified Paragon CRT® Contact Lens eye care professional’s recommendation, you may be fitted with Paragon CRT® Contact Lenses, based on age or activities.
No, these lenses are generally no more difficult to apply or remove than any other contact lenses. 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® Contact Lenses, there are lens removal aids available to assist with this process.
Yes. There are no records of 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 pre-treated correction were -4.50D, it would take a few days longer to return to normal than if the pre-treated correction was -1.50D.
You will be supplied 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.
Orthokeratology with Paragon CRT® Contact Lenses is different than wearing regular daytime contact lenses. If you discontinue wear for one night, your vision may be impaired the next day. Previously worn glasses or daytime contact lenses may not help and replacement is necessary. Having a spare pair of Paragon CRT® Contact Lenses is strongly recommended. Please ask your eye care practitioner for additional information.
If regular contact lenses are covered under your vision care plan, orthokeratology with Paragon CRT® Contact Lenses may be partially covered. Some plans also cover specialty lenses or medical devices. You should check with your benefits plan administrator.
Only your certified eye care professional can determine if you are a Paragon CRT® Contact Lenses candidate. Many patients with slightly dry eyes do well with Paragon CRT® Contact Lenses. Since you are wearing the lenses only while sleeping, the closed eye minimizes evaporative loss of tears and may give dry-eye patients great vision without compromising the ocular surface.
Paragon CRT® Contact Lenses are worn at night while you are sleeping. This eliminates any discomfort normally experienced while wearing contact lenses during the day. Your eye care professional can determine if you are a candidate for Paragon CRT® Contact Lenses.
Paragon CRT® Contact Lenses are designed to correct myopia with up to 1.75 diopters of astigmatism. Your certified eye care professional can determine if you are a candidate for Paragon CRT® Contact Lenses.
