How does it work?
This is a revolutionary non-surgical procedure that may eliminate the need for glasses or daytime contact lenses. It improves vision by gently reshaping your eyes while you sleep using specially designed therapeutic contact lenses. You insert the specially fitted lenses at bedtime. Upon awakening, you remove the lenses and have clear, sharp, natural vision for the rest of the day.
This safe and effective treatment can correct near-sightedness (including high prescriptions), farsightedness, astigmatism and presbyopia (blurred near vision). It is a great alternative to LASIK for those who don't want the risk or are not ready for surgery.
When a person cannot see clearly, it is because their eye is too long, too short, or the surface is misshaped. Images fail to reach or focus on the retina. This produces blurred or distorted vision.
In order to create a therapeutic lens, the surface of your eyes is mapped using a high tech instrument called a topographer. This allows your doctor to create a custom lens specifically designed for EACH of your eyes and its unique visual problems. This Ortho-K lens is manufactured using high-speed computer assisted lathes and made from an advanced highly oxygen permeable material which allows your eye to breathe overnight and maintain excellent health.
Is It Known By Other Names?
Orthokeratology was first used to correct nearsightedness over forty years ago. While the procedure has benefitted from the latest technological breakthroughs over the years, it has accumulated many different names to describe the same procedure. Orthokeratology is also known as Ortho-K; Corneal Refractive Therapy or CRT; Vision Shaping Technology or VST; Accelerated Orthokeratology or AOK; Gentle Vision Shaping System or GVSS; Gentle Molding and finally Overnight Corneal Reshaping or OCR. These procedures may differ slightly in technique, but all fall under the Orthokeratology umbrella. So when you hear the many names of Orthokeratology, don't be confused. They are all referring to reshaping the cornea of the eye with a therapeutic contact lens worn overnight, so you may see all day long with limited need for daytime glasses or contacts.
How Long Does It Take?
It can take from one to four weeks to achieve excellent vision. However, some people achieve this in as little as one day. The speed depends in part on your initial prescription.
During the first few days of the Ortho-K process while your cornea is being resculpted, your doctor may fit you with a temporary soft contact until excellent vision is achieved.
Is It Safe?
Ortho-K is a very safe and reversible procedure. It was approved by the FDA in 2002. However, as with the wear of any type of contact lens there is a slight risk of complications. The most common risk is eye infections. This risk is greatly minimized by adopting a regime of very careful cleaning and disinfecting, by wearing the lenses as prescribed by your doctor and by maintaining the necessary progress visits.
The number of children that are becoming myopic (nearsighted) has been growing rapidly over the last 25 years and is expected to impair fully 50% of the world's population by the year 2020. This rapid increase is due in part to children spending more time studying, reading and using the computer rather than playing outdoors. The Centers for Disease Control (CDC) now views progressive myopia as an epidemic.
Increasing myopia causes poor vision. But more importantly, it can lead to sight threatening conditions like retinal detachments and glaucoma. The earlier a child exhibits myopia, the more likely they will progress to dangerously high levels.
What can we do to stop this myopia epidemic?
Paragon CRT® Contact Lenses are a specifically designed FDA-approved therapeutic contact lens worn only while sleeping. This eliminates the dryness and discomfort of daytime c ontact 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 (orthok), and it's temporary and reversable.
Will Paragon CRT® Contact Lenses improve my vision better than traditional glasses or contacts?
The treatment results should equal the vision correction provided by traditional glasses or contacts. Paragon CRT® Contact Lenses are designed to temporarily treat nearsightedness (myopia), and may provide a solution that may not be avialable through the use of traditional glasses or daytime contacts.
How long does it take to start working?
Most patients see noticeable improvement in the first few days, and complete vision correct is expected within 1-2 weeks.
Is orthokeratology with Paragon CRT® Contact Lenses safe?
Yes. Wearing Paragon CRT® Contact Lenses is safe, and effective. Even though the lenses are worn only while sleeping, wearing any contact lens has some level of risk. It is important to always follow the wearing schedule outlined by your eyecare practitioner as well as follow proper lens care techniques by cleaning and disinfecting your Paragon CRT® Contact Lenses each day.
