What is Orthokeratology (Ortho-K)?

Orthokeratology (Ortho-K) is a corneal refractive therapy which will temporarily reduce your refractive errors without a surgical procedure.

Ortho-K utilizes custom made rigid gas permeable contact lenses to reshape the cornea while you sleep for at least 7 hours giving the patient a temporary correction of myopia (nearsightedness) and minor astigmatism. Ortho-K lenses are FDA approved specialized contact lenses to help slow down the progression of nearsightedness.

How does Ortho-K work?

Who is a candidate for Ortho-K?

  • No age restriction; Yes, it's for all ages!
  • The Ortho-K is for healthy individuals of any age who are nearsighted.
  • The athletes like swimmer, basketball player, water polo player... etc.
  • The Ortho-K is perfect for patients who do not want to wear glasses nor contact lens during the day time.
  • Patients are unable to wear contacts due to allergies.
  • Patients suffer from DRY EYES, making contact lens wear impossible.
  • Patients interested in LASIK but are not quite ready.
  • Children who have moderate to severe myopia progression. Your child eye sight is getting worse and worse every year.

The best candidates are children who are 5 years old or above with above -1.00 refractive error with no greater than -6.00 and preferably with anyone no greater than -1.75 astigmatism.

Is it Safe?

Ortho-K is a very safe and reversible therapy.  It was approved by the DFA in year 2002. As any contact lens wear, Ortho-K has very little risks such as potential infection and eye discomfort due to poor hygiene and lens care.  The risks can be avoided and managed when patient adopting a regime of very careful cleaning and disinfecting, by wearing the lenses as prescribed by doctor and by maintaining the necessary progress follow-up visits.
