Orthokeratology (Ortho-K) is a corneal reshaping therapy (CRT) that uses specialized ridged gas permeable (RGP) contact lenses worn overnight to correct nearsighted and farsighted eyes, with or without astigmatism. A non-surgical alternative to laser eye surgery to successfully control the progression of near- and farsightedness.

Who can Benefit from Ortho-K?

  • Individuals who enjoy SPORTS activities (e.g. swimming, skiing, basketball, and etc…).
  • People who suffer from DRY EYES and ALLERGIES, making contact lens wear difficult.
  • Individuals who prefer to be glasses and contact lens free during day-time
  • Children with PROGRESSIVE myopia/hyperopia with astigmatism, who are too young for surgery
  • Individuals with jobs that requires excellent vision without eyeglasses

Is Ortho-K Safe?

Ortho-k treatment is FDA approved to be safe for overnight wear if fitted by certified professionals. Treatment for Ortho-K is reversible, patients can safely discontinue the wear of these contact lenses and their vision will return back to its original myopic or hyperopic state. Unlike surgical procedures, the corneal tissue is not permanently incised or vaporized by a laser. As with all contact lenses, proper lens care and handling must be performed to maintain eye health.
