Orthokeratology offers a non surgical way to correct nearsightedness and, in some cases, mild astigmatism or farsightedness. The treatment is reversible, and results are maintained with consistent nightly wear.
Orthokeratology involves wearing a custom gas permeable lens during sleep to temporarily reshape the cornea. The effect is similar to dental braces but for the eyes. When the lenses are removed each morning, light focuses properly on the retina, allowing clear daytime vision.
Your eye doctor maps the curvature of your cornea with a corneal topographer, then designs a lens that is slightly flatter in the center. Overnight, the lens gently flattens the cornea, reducing its power and letting light reach the retina sharply. If you stop wearing the lenses, the cornea slowly returns to its original shape and the refractive error comes back.
Ortho-k lenses are made of materials that allow high oxygen flow, yet proper care is essential to keep the eyes healthy.
The overall risk is similar to that of soft contact lenses. Because there is no surgery, complications linked to refractive surgery do not apply. Any pain, light sensitivity, or persistent redness should prompt an immediate visit to your eye doctor.
Most people tolerate ortho-k well, but possible issues can occur, especially with poor hygiene or inconsistent wear.
Because the lenses are custom, reaching your best vision may take several visits and some patience.
It can take two weeks or more to reach maximum clarity, though some patients notice improvement in just a few days. Higher prescriptions may need extra time. During adaptation you might see halos and could need temporary low-power glasses.
Studies show ortho-k can slow the progression of childhood myopia. The rigid lenses limit corneal growth, which is linked to increasing nearsightedness.
Because ortho-k is reversible, patients can still choose refractive surgery later. Lenses must be stopped for several weeks to months before surgery so the cornea can return to its natural shape.
Cost, handling, and hygiene all play a role in deciding if ortho-k is right for you.
Fees vary by doctor, prescription strength, and number of lenses needed. A typical range is $1,000 to $2,000 for both eyes, with complex cases reaching up to $4,000. Additional costs include replacement lenses, cleaning solutions, and follow-up visits.
Place the lens on your fingertip and gently apply it to the colored part of the eye. Following the same order each night, such as right eye first, helps avoid mix-ups. Your eye doctor will demonstrate safe insertion and removal techniques.
Good hygiene keeps your eyes comfortable and reduces infection risk.
Orthokeratology can give you the freedom of clear daytime vision without surgery. If you are active, work in dusty settings, or want to slow a child’s myopia, talk with us about whether ortho-k is a good fit for your eyes and lifestyle.
