Orthokeratology is a non-surgical method of decreasing mild to moderate myopia and astigmatism. Myopia, or nearsightedness, causes light to be focused in front of the retina rather than on it, resulting in blurry vision when looking at distant objects. Here at Linda Vision, Dr. Linda Vu, a board-certified ophthalmologist, uses a form of Orthokeratology called Corneal Refractive Therapy (CRT) by Paragon Vision Sciences. CRT was approved by the FDA in 2002, and has since improved the lifestyle and vision of people of all ages by reducing the need for glasses and daytime contact lenses.
CRT uses special gas permeable contact lenses to reshape the cornea while you sleep. Although the lenses are only worn at night, the cornea retains its altered shape and corrected focus throughout the daytime. This means that CRT patients no longer have to deal with the hassle of glasses or dryness and irritation caused by daytime contact lenses. The temporary correction of myopia not only allows patients to see clearly, but it may reduce changes in prescription. Our Corneal Refractive Therapy uses Paragon CRT lenses. These lenses are produced by Paragon Vision Technology, the first company to get FDA approval for overnight corneal reshaping lenses.
