Ortho-k lenses, sometimes compared to retainers for the eyes, are overnight contact lenses that gently flatten the front of the cornea while you sleep. You put them in at bedtime and take them out in the morning. Because the cornea has been temporarily reshaped, light focuses more clearly, so many patients see well during the day without glasses or daytime contacts.
The vision correction from Ortho-K is temporary. If you stop wearing the lenses, your cornea gradually returns to its original shape. Results usually develop over the first several nights to weeks, and to maintain them, you'll need to wear your lenses on the schedule Dr. Adeleke recommends. Like any overnight contact lens, Ortho-K carries a risk of eye infection, so proper cleaning, lens care, and regular follow-up visits are essential.
