FAQs for Ortho-K Contact Lenses

Published on January 31, 2021 ​​​​​​​


Orthokeratology (Ortho-K) is a term used to refer to a non-surgical procedure used to reshape the eye curvature. Ortho-K uses specially designed contact lenses to gently reshape the eye curvature over time. This revolutionary non-surgical procedure helps to fix refraction errors. The patient gets fitted lenses that they can use at night. When they wake up, they have hours of clear vision. Here are frequently asked questions about Ortho-K treatment.


How Does Ortho-K Work?


The concept of Ortho-K is like orthodontics for the eyes. It is like making braces but for the cornea. The cornea is made of clear, flexible tissue. Its work is to focus light on the retina. If it is oddly shaped, then the light hits the retina at the wrong angles resulting in blurry vision. Ortho-K lenses are specially made to change the shape of the cornea as the patient sleeps. In the morning, the patient can see clearly, but by the end of the day, the cornea has reverted to an irregular shape. These lenses have to be worn for some time for them to work.


What Problems Are Solved by Ortho-K?


Ortho-K lenses are used for treating refractive problems. They are used widely to treat myopia, otherwise known as nearsightedness. Myopia happens when the cornea’s curve is too pronounced. They are also used to treat the opposite of myopia, which is hyperopia. Hyperopia, also known as farsightedness, occurs when the curve of the cornea is too gentle. The third problem is astigmatism, which is a common refractive condition. Astigmatism occurs when the patient has an irregularly shaped cornea or a cone-shaped cornea.


Can People of All Ages Get Ortho-K?


The Ortho-K procedure is suitable for people of all ages. However, it is best suited for teenagers and young adults since their eyes are still developing. It is also good for treating childhood myopia. People who are not eligible for LASIK surgery also benefit from Ortho-K.


How Long Do the Effects of Ortho-K Last?


The effects of this treatment vary from patient to patient. Young patients whose eyes are still developing have better results. It is easier to shape their cornea, and the results last longer. However, some patients have severe conditions that require more patience. For the procedure to give the best results, the contacts should be worn every night even when the patient experiences a sharp vision.


Does Ortho-K Replace Glasses Completely?


Your eye doctor recommends lenses that will work on your specific problem. In the beginning, the results may not be as sharp. The patient can continue using contact lenses or glasses. However, with the continued use of Ortho-K lenses, the image becomes sharper, and the patient can stop using glasses during the day.


What About Dry Eyes?


Many people are afraid of Ortho-K because eye contact lenses give them dry eyes. However, a good number of people report no problem with dry eyes. Since the lenses are worn at night, they irritate the eyes less. Closed eyes have minimal movement and tears evaporation; hence dry eyes are not a major concern with Ortho-K.
