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 is also referred to as "ortho-k" corneal refractive therapy or vision shaping.
Some orthokeratology lens designs are available for farsightedness and presbyopia. Research has also demonstrated that orthokeratology lens designs slow the progression of myopia.
Good candidates for orthokeratology include children and adolescents with progressive 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.
