What is orthokeratology?

Ortho-k uses specially designed, gas permeable contact lenses to temporarily reshape your cornea while you sleep. Vision improvements are reversible but can be maintained if you keep wearing the lenses as directed.

What visual problems can ortho-k correct?

Ortho-K is most commonly used to temporarily correct myopia (nearsightedness).

In some cases, it can be used to correct lesser degrees of astigmatism and farsightedness. Orthokeratology has been an effective optical treatment in the control of myopia in children.

How does ortho-k work?

The lenses work by flattening the center of the cornea, changing how light is bent as it enters the eye. Most orthokeratology lenses are worn overnight to flatten the cornea, then removed during the day. These overnight lenses are rigid, gas-permeable lenses that are sturdy enough to reshape the cornea, but also allow oxygen through so your eye stays healthy.

Candidate for ortho-k?

Most people with mild to moderate myopia are good candidates. If you are tired of wearing glasses or contact lenses during the day, consider ortho-k.
