Orthokeratology for MyopiA Treatment
At Eye & Vision Clinic, we provide the latest technology available to meet your vision needs. Myopic treatment is available with Orthokeratology. We are certified to prescribe Paragon CRT contact lenses for non-surgical Corneal Refractive Therapy. By wearing the prescribed CRT lenses overnight, the cornea curvatures are gently reshaped while sleeping, which temporarily reduces myopia and also potentially controls myopia progression so that you do not depend on wearing glasses or contacts during the days.
What is Myopia ?
Myopia, also known as nearsightedness, is a common vision condition where affected people cannot see distance objects well but can see close objects clearly. Myopia develops when the cornea (the clear layer on the front of the eye) overly curved that generates too much focusing power or when the eyeball is excessively elongated, light images of objects cannot be focused properly on the retina (a light-detecting neural tissue lying in the back of the eye), making distant vision blurry but near vision remains clear.
The majority of myopia occurs in the school age children where the eyes continue to grow. It is the most common cause of impaired vision in people under the age of 40. High myopia also increases the risk of serious eye problems such as retinal detachment, cataract, glaucoma, myopic macular/retinal degeneration and myopic choroidal neovascular membrane.
Myopia Treatment Options
Myopia is commonly treated with prescription glasses and traditional contact lenses, which help refocusing lights correctly onto the retina and give clear vision.
Refractive Eye Laser Surgeries such as LASIK and PRK are the treatment options for the right candidates in adult myopic patients. Phakic Intraocular Lenses surgery also an option for certain very high myopic patients, where a small thin intraocular lens of right power is implanted permanently inside the eye in front of the natural crystal lens to help reduce the needs for glasses or contact lenses.
Orthokeratology described in this section is another option for treating nearsightedness.
Orthokeratology with Paragon CRT® Lenses for Corneal Refractive Therapy
Orthokeratology, also known as Ortho-K or Corneal Refractive Therapy, is a non-surgical procedure to temporarily reshape the cornea in a controlled manner to correct myopia. It works by fitting specially designed, high oxygen-permeable Rigid gas permeable (RGP) contact lenses that flatten the corneal curvatures during night time wear while sleeping, and thus correcting myopia and allowing clear vision during the day without glasses or contact lenses.
Paragon CRT® Corneal Refractive Therapy contact lenses were the first FDA approved overnight corneal reshaping lenses for all ages. They are prescribed for correcting myopia of up to -6.00D sphere with or without 1.75D cylinder. To maintain the orthokeratology effect of myopia reduction, Ortho-k lenses must be worn overnight on a regular basis to allow you to see clearly without the use of glasses or contact lenses during waking hours of the day.
Contact lenses are medical devices that are regulated by FDA. Ortho-k with Paragon CRT® Contact Lenses carries the same risks as other types of contact lenses. They also have risks that are not typically associated with other types of contact lenses, such as variable vision late in the day that should decrease with time.
Ortho-k with CRT contact lenses is generally safe, effective, predictable and reversible. Reduction of nearsightedness can reduce your dependency on glasses and contact lenses. In addition, it potentially slows the progression of nearsightedness. You or your child may be a good candidate for this non-surgical vision correction procedure.
