  • Notes:
    Optimal Orthokeratology can be performed on a broad base of the population that requires vision correction. However only a Certified Optimal Orthokeratologist can determine if you are a good candidate for OOK therapy. If your OOK specialist determines that you meet the basic criteria, the success of the therapy is based on the specific shape of your cornea and its refractive error. Your cornea must be evaluated by an instrument called a corneal topographer (a camera which takes a picture of the shape of the surface of your eye).

    If you are determined by your Optimal Orthokeratologist to be a good candidate for the therapy, then the goal is to provide you with the following:
  • 20/20 vision or better
  • Crisp, clear vision all day and evening without aid
  • No dependency on glasses or daily contact lenses
  • Comfortable OOK lens wear with eyes open or shut
  • After 6 months to a year, reduce OOK wear schedule to 1 to 2 nights per week
  • Tell me how it works.
