Ortho-K
Dr. Dovzhuk is more experienced with ORTHO-K than any doctor in New York City
It is Corneal Refractive Therapy or CRT. CRT is FDA approved for all ages to correct myopia, also known as nearsightedness. CRT is a therapeutic contact lens that gently and temporarily reshapes your cornea while you sleep. When you awake, simply remove your lenses and experience great vision all day. No more torn lenses, broken frames or discomfort sometimes associated with daytime contact lens wear. Whether you are playing sports or applying makeup, with CRT nothing stands between you and excellent vision. If you’re one of the many individuals who live an active lifestyle, Paragon CRT® Contact Lenses may be the option for you!
Paragon CRT® Contact Lenses are a specially designed FDA-approved therapeutic contact lens worn only while sleeping. This eliminates the dryness and discomfort of daytime contact lenses, giving you freedom when it matters most. Paragon CRT® Contact Lenses gently reshape the cornea without permanent alteration. This procedure is known as orthokeratology (ortho-k), and it’s temporary and reversible.
Since it is FDA approved for all ages, it is also suitable for correction of myopia in children!
Myopia FACTS
- Myopic eye is longer than the non-myopic eye
- Instead of light focusing on the back of the eye (the retina), light focuses in front of the eye, causing blurred vision
- The onset of myopia at an early age brings with it the likelihood of life-long eye care, which can effect visual performace in the classroom.
- Later in life, if not treated properly, high levels of myopia doubles the risk of serious ocular health problems such as retinal detachment, cataract and glaucoma, which can lead to vision loss and blindness.
- The causes of myopia are both genetic and environmental
- It is estimated that the number of people with myopia will continue to grow
Paragon CRT® Contact Lens Design and Initial Fitting
Beyond a comprehensive eye examination, the following outlines the basic steps involved in the fitting process:
A corneal topography will be performed to determine the shape of your cornea and assist in the selection of an initial diagnostic lens. If necessary, additional diagnostic lenses will be prescribed until we obtain the ideal corneal-treatment lens fitting relationship. It is believed that the ortho-k effect occurs in the corneal epithelium, which is the top layer of the cornea. The treatment lens is specifically designed to alter the shape of this tissue. As illustrated in this cross section view above, the treatment lens is flatter than the cornea at its center and takes a plateau shape toward its periphery.
We will provide a temporary pair of Paragon CRT® Contact Lenses that you will use during your initial treatment period.
Paragon CRT® Contact Lens Wear
While wearing the Paragon CRT® Contact Lenses, the surface differences between the lens and the cornea, forces the cornea (epithelium) to take on a new shape. The corneal tissue begins to take on the shape of the back surface of the treatment lens, which is designed to correct for myopia and astigmatism.
Paragon CRT® Contact Lens Removal
After wearing the lens overnight, the Paragon CRT® Contact Lens is removed revealing a new corneal surface shape. You should notice improved vision, however, during the first few days of treatment, and depending on your prescription, you may notice that the effect will fade quickly. However, with every successive night of wear, the effect should become greater and last longer. It will take between 7 to 14 days of treatment to obtain unaided-vision throughout your day.
Will Paragon CRT® Contact Lenses improve my vision better than traditional glasses or contacts?
traditional glasses or contacts. Paragon CRT® Contact Lenses are
designed to temporarily treat nearsightedness (myopia), and may provide a
solution that may not be available through the use of traditional
glasses or daytime contacts.
How long does it take to start working?
Most patients see noticable improvement in the first few days, and complete vision correction is expected within 1-2 weeks.
Is orthokeratology with Paragon CRT® Contact Lenses safe?
Can I get LASEK after wearing Paragon CRT® Contact Lenses?
Of course. If you decide that you want to stop wearing lenses and get LASEK instead, feel free to contact us. Because Non-Cutting is the Safest™
Do you want to stop your myopia from progressing?

Office Patient Instructions
Below contains the same patient instructions our office provides before an Ortho-K visit. These instructions explain what records to bring, how insurance may apply to Ortho-K, what to expect during the evaluation, and how Ortho-K benefit certain patients.
If you made it this far, you can see our process and our thoroughness to get you best equipped for your visit.
Dear PT NAME
You are coming in for Ortho-K on
DAY OF WEEK, MONTH, DATE, TIME AM/PM
You’ll save a LOT of time by replying with your last Ortho-K prescription, which you should get from your eye doctor. If you can’t, that’s fine, but your visit will then take twice as long (1 hour instead of 30 minutes)
If your last Rx is >1 year old, tell that office that we are NOT going to reuse it, we’re going to UPDATE it, so they release it. You may have to complete a HIPAA release.
If you want new lenses, the cost is $500 per lens, or $1000 for 2 lenses. If you want a warranty, it’s $100 more, but then a replacement lens will cost only $100 if you lose or break one within the next year. Tell our doctor what your decision is about this warranty
We use Paragon lenses, which are the #1 brand in the world. Dr. Chynn and Dr. Dovzhuk are both MDs and eye surgeons, and Dr. Dovzhuk has prescribed over 1,000 Ortho-K lenses—more than any other eye MD in NYC
Most Ortho-K patients eventually think about getting lasered to permanently correct their vision. If you’re in your late 20s, your prescription is now probably stable enough for this. Please ask Dr Chynn or Dovzhuk to review your options. If you want to remain in your Ortho-K lenses, that’s fine, too!
Thanks and looking forward to helping you see clearly
