Corneal Reshaping Therapy
(Orthokeratology / Ortho-k)
With Corneal Reshaping Therapy you can be free of daytime contact lenses or glasses and enjoy great vision during your daily activities without undergoing surgery! Recent clinical research combined with the latest corneal surface mapping technology found at Twenty Twenty Eyecare make this possible. Corneal Reshaping Therapy is a non-surgical process developed to reshape the cornea while you sleep. The result is the temporary correction of nearsightedness with or without astigmatism.
Similar in appearance to standard contact lenses, these therapeutic lenses gently reshape the corneal surface during sleep to provide clear, natural vision when the lenses are removed upon waking.
Active individuals can freely participate in sports without the interference of glasses or contacts. Eye irritation and dryness, sometimes associated with contact lens wear due to outside dust and pollutants, are also eliminated.
Orthokeratology is a process that uses specially designed GP contact lenses to temporarily reshape the contour of the cornea to reduce myopia (nearsightedness).
Orthokeratology is nicknamed “ortho-k” and sometimes called corneal reshaping (CR), corneal refractive therapy or vision shaping. Some new ortho-k lens designs are also available for farsightedness and presbyopia. Research has also demonstrated that orthokeratology lens designs slow the progression of myopia. Good candidates for orthokeratology include youngsters age 8 to 12 with progressive myopia, as well as most adolescents and adults, although the best success is with people under age 40. Ortho-k is recommended for low to mild nearsightedness (-4 diopters or less). People who are not good candidates include those with dry eye syndrome, a large pupil size, or high myopia.
The Orthokeratology Process
If your eye care professional feels you are a good candidate for orthokeratology, you will wear specially designed GP lenses at night only. In the one- to two-week treatment phase, your nearsightedness is gradually reduced. Since your vision will be changing, you’ll need to wear disposable soft lenses during the day. Once the treatment is over, you can wear the GP lenses at night only and see well during the day without any corrective lenses. Some people need to wear their lenses only every other night, or even once or twice a week, to maintain the effect. You will need to see your eye care professional regularly to ensure your lenses are fitting well and your eyes are healthy. Since during sleep the lenses fit tightly on the eye, it’s especially important to clean and disinfect the lenses upon removal each morning.
