Orthokeratology is a procedure by wearing computer guided specially designed Rigid Gas Permeable contact lenses (some call mold, retainer, Ortho-k  or OK lens) overnight to temporarily alter the contour of the superficial cornea. Upon waking you can see clearly without the need to wear spectacle or contact lens in the day, and the altered cornea contour also provides all day Myopia Control for children.

  • Unlike refractive surgeries, ocular condition and vision generally return to their original state within few weeks of stop wearing the OK lenses.

Disadvantages:

  • Vision correction with Ortho-k is not permanent, wearers need regular wearing to maintain functional vision.
  • Wearers have to spend more time initially for Ortho-k procedure and follow-ups to ensure corneal health is maintained.
