Orthokeratology or Ortho-K is a method of vision correction that eliminates the need to wear eyeglasses or use contact lenses during the day. The procedure, which is also known as overnight vision correction or corneal reshaping, involves the use of specially designed rigid gas-permeable contact lenses to gently reshape the cornea. Placed at bedtime and removed in the morning, these lenses precisely mold the front surface of the eye so that clear, crisp vision can be enjoyed throughout the day.
Ortho-K provides a safe and therapeutic option for vision correction in children, teens, and adults. Commonly used to address mild to moderate myopia (nearsightedness), other types of refractive errors may also be treated with this method of care. Ortho-K offers an effective, non-surgical alternative to LASIK and other refractive surgeries for individuals who because of their youth or issues involving the health of their eyes are not candidates for those procedures. It is also a good choice for people who are active in certain sports, or have jobs in environments where wearing contact lenses can be more difficult.
With Ortho-K, vision markedly improves as the reshaped cornea correctly focuses light on the retina to produce clearer images. Thanks to Ortho-K, perfect or near perfect vision can be enjoyed throughout the day. While some people experience significant improvements in vision after just a night or two of wearing Ortho-K lenses, more time may be needed for complete vision correction in cases involving larger refractive errors.
Besides being non-invasive and suitable for patients of all ages, treatment with Ortho-K is completely reversible. This means that it can be discontinued at any time without any permanent changes to your eyes; thereby leaving you free to once again explore wearing eyeglasses, contact lenses during the day or having a LASIK procedure.
