Now you can be free of daytime contact lenses or glasses
and enjoy great vision during your daily activities without undergoing surgery!
Recent clinical research combined with the latest corneal surface mapping technology, computerized manufacturing and space age oxygen-breathing materials have brought new science to corneal reshaping.
Corneal Refractive Therapy is a non-surgical process clinically developed to reshape the cornea while you sleep. The result is the temporary correction of myopia with or without moderate astigmatism.
Similar in appearance to standard contact lenses, Paragon CRT therapeutic lenses gently reshape the corneal surface during sleep to provide clear, natural vision when the lenses are removed upon waking.
Q: Will CRT improve my vision better than traditional glasses or contacts?
A: The treatment results should be equal the vision correction provided by traditional glasses or contacts. CRT is designed to temporarily treat/correct nearsightedness (myopia). Also studies suggest that wearing lenses such as CRT helps to slow or even stop progression of myopia. CRT may provide a solution that may not be available through the use of traditional glasses or daytime contacts.
Q: How long does it take to start to see effect from the treatment?
A: Most patient see dramatic improvement in the few days, with complete vision correction within 1-2 weeks
Q: Is CRT safe?
A: Yes. Part of safety profile lies in the fact if you stop wearing CRT lenses, your vision will return to its previous level
Q: Is CRT Permanent?
A: No it is 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.
Q: What should a patient expect during the 10-14 day treatment process?
A: After patient begun treatment, but before sufficient treatment is realized, old glasses or contacts will no longer be the appropriate prescription. Usually we provide patient with temporary one day disposable soft contact lenses in different prescriptions.
Q: Are there any risks involved with wearing CRT?
A: The risk of wearing CRT lenses is similar to the risks involved wearing any other types of contact lenses.. These are infection and corneal abrasion.It is not expected that the CRT lenses will provide a risk that is greater than other contact lenses that are worn during sleep. There were no serious adverse events reported in the Paragon CRT FDA clinical study.
Q: Will I be able to see with CRT lenses on?
A: Yes. One of the great features of the 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 CRT lenses 24 hours a day, on or off.
Q: How often will I have to replace my CRT lenses?
A: CRT lenses will have to be replaced annually. 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.
Q: How do I care for my CRT lenses?
A: Your lenses should be chemically disinfected after each use. We will instruct you about which care system is best for you.
Q:Is Corneal Refractive Therapy painful?
A: NO. Therapy is not painful. Initially, you may have a slight awareness of the lens. You will not feel the lenses when you sleep and there is no sense of physical corneal change, just visual improvement when lenses are removed.
Q: Are there age restrictions for Corneal Refractive Therapy?
A: No. The FDA placed no age restrictions on candidates for Corneal Refractive Therapy with CRT. It can be a great option for kids that are active in sports or any other extra curricular activities.
CRT lenses are also great for older and presbyopic (requiring reading glasses or bifocals)
Q: Are CRT lenses difficult to apply or remove?
A: No. These lenses are generally no more difficult to insert or remove than any other similar contact lens modality. You may want to instill 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 CRT lenses, there are lens removal aids available to assist this process
If you are one of many individuals who experience dry eye or contact lens discomfort CRT may be a treatment option for you. In fact many successful CRT patients were previous soft lens wearers. If you experience dry eye, LASIK may be not an appropriate option, making CRT lenses an excellent alternative.
