What is Ortho-K (Orthokeratology )?

Orthokeratology, or Ortho-K, is the temporary reshaping of the cornea with specifically designed and fitted contact lenses for the purpose of improving eyesight. The concept is similar to how an orthodontist uses a dental retainer to straighten crooked teeth. Most Ortho-K lenses are used at night to reshape the front surface of the eye. Nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and sometimes presbyopia can all be corrected using Ortho-K. 

Is Ortho-K the Right Option for Me?

Ortho-K is mostly used to treat nearsightedness (myopia). Orthokeratology is a non-surgical option for some people who want to ditch their glasses and avoid wearing contact lenses all the time. This can be a good alternative for the individuals who want LASIK but aren’t ready for surgery. 

For correcting eye problems, Ortho-K Lens is suitable for the following people:

  • People who do not want to wear glasses or contact lenses during the day.
  • People who want LASIK but are under 18 years of age, or have limitations such as unstable eyesight, or a cornea not suitable for LASIK.
  • Contact lens wearers who have dry eyes.
  • Athletes who are not comfortable using eyeglasses or contact lenses.
  • Some occupations that are not suitable for wearing glasses or contact lenses, such as soldiers, pilots, flight attendants, firefighters, etc.
  • Children with progressive myopia.

Prescriptions in the range of +2.00 to -6.00 with no more than -1.75 diopters of surface astigmatism.

How Does Ortho-K Lens Works?

Ortho-K adjusts the cornea’s curve to correct vision problems. The corneal curvature correction is just temporary. The cornea will return to its original shape if 

the corneal molds are discontinued.


Why Is Ortho-K a Great Alternative To LASIK?

  1. It is a non-surgical procedure. The cornea will return to normal in less than two months after discontinuation. 
  2. The prescription changes gradually over time. Ortho-K lenses can be replaced to accommodate changing eyesight without requiring additional surgery.
  3. Even the youngest children can benefit from Ortho-K, while LASIK should be performed on people ages 18 and up.
  4. Many studies show that Ortho-K can help control increases in nearsightedness, so a by-product is myopia control.
  5. There is no risk associated with surgery or problems caused by flap (opened cornea).
  6. No dry eyes. This differs from LASIK, which frequently results in dry eyes after surgery. This is because the procedure destroys the cornea’s sensory endings, which trigger the flow of tears. 
  7. It does not result in scattered lights as this could happen after LASIK surgery.
  8. When compared to LASIK, the cost is several times lower.

I am Interested in Ortho-K, What’s Next?

  1. We will schedule a comprehensive eye exam to evaluate your eye condition. 
  2. Corneal photography will then be used to create a three-dimensional map of the surface curvature of the cornea. 
  3. If you are a good candidate for Ortho-K and want to go for this alternative treatment, the patient or parent/guardian must sign “Corneal Refractive Therapy Agreement” at payment.
  4. A spare pair can be ordered within 90 days (recommended) (fee is applicable).
