What is OrthoKeratology (OrthoK)?

View Video

OrthoK is a non-surgical process clinically developed to reshape the cornea while you sleep. The result is the temporary correction of:

  • myopia (nearsightedness)
  • hyperopia (farsightedness)
  • with or without moderate astigmatism (irregular surface of the cornea)
  • presbyopia (bifocal vision)

OrthoK therapeutic molds gently reshape the corneal surface during sleep and provide clear, natural vision when the molds are removed upon waking.

Because OrthoK offers freedom from glasses and the hassle of wearing contact lenses during the day, this leading-edge technology can enhance the lifestyle of those requiring vision correction. Active individuals can freely participate in sports without the interference of glasses or bother of contacts. Eye irritation or dryness sometimes associated with contact lens wear due to outside dust and pollutants is eliminated.

How OrthoK works

Let’s understand how Corneal Refractive Therapy with OrthoK works to correct Myopia. In the myopic eye, the focusing power is too great. Light focuses in front of the retina, making distant objects appear blurry. When eyeglasses or contacts are worn, light is focused on the retina so that you can see clearly.

Laser surgery is another way to correct myopia. It permanently alters the cornea and corrects the focal point, producing clear vision.

When the OrthoK therapeutic molds are removed in the morning, the treated cornea allows light to focus on the retina. The result is clear, natural vision for all or most of your waking hours.

Are all OrthoK therapeutic molds the same?

No. There are many brands of therapeutic molds, and they have their own strengths and weaknesses.  Dr. Martin has worked with many designs, and as a Member of the Orthokeratology Academy of America, devotes significant time to mastering these nuances so he can pick or custom design the optimal OrthoK therapeutic molds for your eyes.

Some brands of OrthoK therapeutic lenses include:

  • WAVE Custom OrthoK
  • Paragon CRT
  • FARGO OrthoK
  • GOV OrthoK
  • Bausch + Lomb VST
  • and many others

Dr. Martin evaluates every new therapeutic mold design to see if adding to his practice will provide a new benefit to his OrthoK patients.  Every year, he sets aside 5 days to attend the Orthokeratology Academy of America Vision by Design conference, which routinely draws practitioners from 6 continents (apparently, there are no eye docs in Antarctica!). Every year he comes back excited about the direction OrthoK is heading!
