Orthokeratology Contact Lenses

Orthokeratology is a modern process that makes use of specially designed GP contact lenses to temporarily reshape the contour of the cornea to reduce myopia (nearsightedness). Orthokeratology contact lenses change the shape of the cornea while you sleep producing a temporary improvement in vision for waking hours.


Orthokeratology is also referred to as "ortho-k" corneal refractive therapy or vision shaping.

Research has also demonstrated that orthokeratology lens designs slow the progression of myopia.

Adults can also be treated, particularly under 40 years of age.

People who are not good candidates include those with dry eye syndrome, a large pupil size, or high myopia.


Are You A Good Candidate?

Good candidates for orthokeratology include children and adolescents with progressive myopia.

Ideally, your prescription should be in the range -1.00 to -6.00 with no more than -1.75 astigmatism. In some cases your Orthokeratologist will attempt higher prescriptions.

If you have been unable to wear contact lenses for any reason (discomfort, allergies, inconvenience, dryness, etc.), you are also a great candidate because this lens is so easy to use and it’s worn while you sleep. This greatly reduces any discomfort you may have experienced while using conventional contact lenses.

You are also a great candidate if you need excellent vision without the use of contacts or glasses. Ortho-K benefits pilots, police officers, military personnel and those with safety concerns such as professional athletes, parents of small children, lifeguards and many others.

Finally, if you just don’t want to be bothered with wearing glasses or contact lenses during a variety of activities such as hiking, playing sports, swimming, skiing, camping, off-road driving, biking, snorkeling, scuba and more, Ortho-K is for you.
