ORTHO K Lenses or Corneal Reshaping Contact Lenses for Myopia Control.
What is ortho-k?
Orthokeratology (ortho-k) is the fitting of specially designed gas permeable contact lenses that you wear overnight. While you are asleep, the lenses gently reshape the front surface of your eye (cornea) so you can see clearly the following day after you remove the lenses when you wake up.
Ortho-k lenses are prescribed for two purposes:
- To correct refractive errors (primarily short sightedness, but also astigmatism and hyperopia). In some cases, ortho-k also is used to correct presbyopia.
- To slow the progression of childhood myopia.
Ortho-k lenses are also called “corneal reshaping contact lenses” or “overnight contact lenses to correct or control myopia.”
