Myopia Control Management
Imagine a world in which you wear contact lenses at night while you sleep, and then remove them when you wake up in the morning, and enjoy clear, comfortable vision all day long. If this scenario has caught your eye, then you should have an eye exam performed by one of our Insight Eyecare doctors to see if our Corneal Refractive Therapy (CRT) may be the best visual solution for you. CRT is an advanced form of what is commonly referred to as Orthokeratology or ‘Ortho-K’ for short. In the right patients, it is highly effective at providing FREEDOM from glasses and day-time contact lenses.
Why Ortho-K (short for Orthokeratology – literally, the study of aligning or straightening corneas)?
Ortho-K is a non-surgical solution for patients with myopia (nearsightedness) which utilizes special high technology contact lenses that are worn while asleep (like Paragon CRT lenses) to improve vision. Freedom from the common burdens of wearing glasses or daytime contact lenses is the obvious and immediate benefit of Ortho-K, but the long-term eye health benefits last a lifetime. In most cases, our CRT Ortho-K treatment will greatly slow or even stop the progression of nearsightedness, which has become an epidemic in our youth. Highly nearsighted eyes have the following associated eye health risks:
- Cataracts tend to develop sooner in nearsighted eyes.
- Nearsighted people are 2 to 3 times more likely to develop glaucoma, an incurable, potentially blinding disease.
- Highly Nearsighted people have an increased risk of retinal detachment, a medical emergency requiring complex surgery to repair.
How Does Ortho-K work?
To further understand the benefits of Orthokeratology – “Ortho” (aligning/straightening) “kerat” (cornea) “ology” (the study or science of), let us first consider how it works. To do that, we must first consider how your cornea works. The cornea is the transparent, spherical bulge at the very front of your eye. The exact shape and contour of your cornea causes incoming light rays to be bent or “refracted”, in such a way that the inner lens of your eye can focus the incoming light into a clear, sharp image on your retina, the light detecting layer at the back of your eye. The light and images formed on your retina are then transmitted to your brain for “processing” via the optic nerve.
So, the visual process begins with the cornea (more accurately, the tears sitting on the cornea), and the cornea’s exact contour and shape are critically important for proper vision to occur. In fact, it’s the various irregularities – or “out of alignment” qualities – in the shape of the cornea that is most directly responsible for the commonly known “refractive errors” of nearsightedness (myopia), farsightedness (hyperopia) and astigmatism. Each of these refractive errors produces its own unique type of blurry, distorted vision with predictable associated visual complaints.
More Benefits of Ortho-K
Historically, glasses and contact lenses have been the “tool of choice” to resolve these refractive error visual complaints. These medical devices are curved in a very precise fashion that has been uniquely customized and therefore “prescribed” by your eye doctor to “pre-refract” the incoming light before that light even gets to your cornea, thus compensating for your personal type and degree of corneal “out of alignment”. Glasses and contact lenses are a “compensation” for the refractive error that exists; they DO NOT fix, alter, or otherwise result in the SLOWING of this typically worsening or enlarging error, which is unfortunately the common scenario with today’s nearsighted youth – higher and higher amounts of nearsightedness over their lifetime. CRT ortho-k lenses can truly be a quality of life changer in this regard!
Furthermore, while traditional glasses and contact lenses offer widely acceptable vision compensation options, they also can create their own distortions, reflections, and blur from contaminated lens surfaces. With CRT, you can be free from distracting glare caused by dirty, scratched eyeglass lenses and free from fluctuating, blurry vision and stinging dry eyes caused by contact lenses that dehydrate your eyes. In addition, unlike refractive surgeries such as LASIK, the effects of CRT are modifiable over one’s lifetime, and can therefore be adjusted to better compensate for the changing visual deficiencies associated with aging eyesight as we move into our middle adulthood years (presbyopia).
Why Paragon’s CRT Ortho-K Lenses?
When worn overnight, our Paragon CRT contact lenses gently correct the curvature of the cornea, resulting in a corneal shape that focuses light correctly onto the retina. When removed in the morning, distant objects will come back into focus and patients can see clearly without the use of glasses or daytime contacts. Paragon CRT lenses also offer a more natural vision experience because no lenses are being worn during your daytime hours. More importantly, our CRT treatment can greatly reduce and even completely stop the progression of nearsightedness, which is an epidemic problem in today’s youth and carries associated permanent eye health risks over one’s lifetime.
1. Call and schedule a CRT Contact Lens Evaluation (a comprehensive eye health exam may be required if you have not had one within the last 6 months.)
2. Our doctors will precisely map the shape of your corneas and evaluate your refractive error to determine if you are a good candidate.
3. If deemed a good candidate, customized CRT lenses will be ordered and fabricated.
4. Receive training on how to properly insert and remove the contact lenses.
5. Return for follow-up appointments to check on the rate of improved vision!
