The Benefits of Orthokeratology
Would you like to see clearly without wearing contact lenses or eyeglasses but don't want to have refractive eye surgery? Orthokeratology, commonly called ortho-k, may offer the perfect option for you.
What Is Orthokeratology?
Orthokeratology involves wearing special contact lenses at night that flatten your dome-shaped cornea. In addition to protecting your inner eye from debris, your cornea focuses light onto your retina. As light enters the eye, the cornea bends it to ensure that it's focused directly on the retina.
Ortho-k is most often used to treat myopia (nearsightedness). If you're nearsighted, light doesn't quite reach the retina inside your eyes, which makes everything you see in the distance look blurry. Flattening the cornea with orthokeratology corrects this issue. In some cases, Orthokeratology can also be used to treat astigmatism and hyperopia (farsightedness).
When you take out your gas-permeable lenses in the morning, your cornea will retain the shape of the lens, allowing you to see well without glasses or contact lenses. Initially, you'll wear a series of temporary contact lenses that will gradually flatten your corneas over several weeks. Once your optometrist is satisfied with your progress, you'll wear the same pair of contact lenses every night. You'll need to wear the contact lenses every night to maintain your results.
