What is Ortho K?
Orthokeratology (also referred to as Ortho-K, Overnight Vision Correction, Corneal Refractive Therapy and CRT), refers to the creation of gas permeable contact lenses that temporarily reshape the cornea to reduce refractive errors such as myopia, hyperopia and astigmatism.
Now you can be free of daytime contact lenses and glasses during your daily activities without undergoing surgery and enjoy great vision! 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 and provide clear, natural vision when the lenses are removed upon waking. Because Paragon CRT offers freedom from glasses and the hassle of wearing contact lenses during the day, this leading-edge technology can enhance the lifestyle of those requiring vision correction. Active individuals can freely participate in sports without the interference of glasses or bother of contacts. Eye irritation or dryness, sometimes associated with contact lens wear due to outside dust and pollutants, is eliminated.
How Paragon CRT® works?
In the myopic eye, the focusing power is too great. Light focuses in front of the retina, making distant objects appear blurry. When eyeglasses or contacts are worn, light is focused on the retina so you can see clearly.Laser surgery is another way to correct myopia. It permanently alters the cornea and corrects the focal point,producing clear vision.Today, Corneal Refractive Therapy provides a new option for patients. Paragon CRT lenses correct myopia, with or without low or moderate astigmatism, by gently reshaping the cornea while you sleep. When the Paragon CRT lenses are removed in the morning, the treated cornea allows light to focus on the retina. The result is clear, natural vision for all or most of your waking hours
