Eye Retainers

Eye Retainers

Eye Retainers or Orthokeratology (OrthoK) is a specially shaped contact lens that is worn overnight to gently correct nearsightedness back to normal 20/20 vision.

OrthoK has many names including:

  1. Gentle Vision Reshaping
  2. Gentle Cornea Reshaping
  3. Cornea Reshaping Technology
  4. LASIK without surgery

As you can probably tell from the names above, Eye Retainers involves reshaping your cornea!  A great comparison are teeth retainers in that they are a mold that you wear overnight to keep your cornea or teeth aligned. But you need to understand a couple of ocular terms before you continue…

  1. Cornea – the front tissue of the eye. Clear in appearance and sits in front of your iris (the colored part of your eyes).
  2. Emmetropia – no prescription (0).  When light is focused in emmtropic eyes, it is perfectly focused on the retina (back tissue of the eye.)
  3. Myopia (nearsightedness) – myopic eyes have a more curved cornea than emmetropic eyes; this results in light being focused inside of the eye.
Light is focused in front of the retina in myopic eyes (near sightedness).
Light is focused in front of the retina in myopic eyes (near sightedness).

Now, OrthoK technology is an FDA approved modern non-surgical contact lens.  The OrthoK lens involves gently reshaping a myopic eye to an emmtropic eye overnight.

Light is focused perfectly on the retina in emmetropic or OrthoK eyes. Notice the cornea is flatter than Myopic eyes (picture above.)

Here are 10 interesting points about OrthoK lenses:

  1. Reversible!
  2. No Surgery!
  3. Worn OVERNIGHT only!  And FDA approved!
  4. The highly oxygen permeable contact lens allows overnight wear!
  5. Freedom from OrthoK lenses, Glasses or Contact lenses during the day!
  6. If you miss a night, it does not mean your vision goes back to your original vision!
  7. Cleaning and storing does not require much extra time!
  8. Latin meaning: “ortho” = straight, and “keratology” = the science of altering the shape of the cornea.
  9. Approved for all ages, including children.
  10. Allows great field of view and no distortions!

The OrthoK lenses are also a great option for dry eyes patients / sufferers, allergy sufferers, and others who require a glasses free or contact lens free solution during the day (athletes, factory workers, water related occupations / hobbies – ie. scuba diving).
