Orthokeratology (ortho-k) is a revolutionary solution that helps improve vision while you sleep. This procedure uses special contact lenses to reshape the cornea overnight. It provides clear vision throughout the day without the need for corrective eyewear. Here is the science and how its reshaping technique can benefit your vision. 


Understanding Corneal Reshaping


Ortho-k works on the principle of corneal reshaping. This involves a controlled process that gradually flattens the curvature of the cornea. The new shape corrects refractive errors such as myopia (nearsightedness) and astigmatism.


How Ortho-K Works


The process begins with a comprehensive eye examination to determine your candidacy. Your eye care professional takes precise corneal measurements to create custom contact lenses. The doctor will give you instructions to wear these overnight while you sleep.

During sleep, the lenses reshape the cornea by gently exerting pressure on its surface. The lenses work by redistributing the tears in the tear film layer between the lens and the cornea. This tear redistribution helps reshape the cornea, resulting in clearer vision.


The Benefits


  • Clear Vision Without Glasses or Daytime Contacts - You experience clear vision throughout the day. You will not need glasses or daytime contact lenses. This is ideal for individuals involved in sports or outdoor activities. 

  • Nonsurgical and Reversible – Ortho-k is a non-surgical procedure. This makes it a safe and reversible vision correction option. Ultimately, your vision can revert to its pre-ortho-k state.

  • Myopia Control – The procedure has shown promising results in slowing myopia progression by gently reshaping the cornea. This reduces the risk of future eye complications associated with high myopia.

  • Convenience and Comfort - Ortho-k lenses are worn overnight. You can enjoy clear vision during the day without needing daytime contact lens wear. This eliminates the discomfort and dryness often associated with contact lenses.


Suitability And Considerations


Ortho-k is suitable for many individuals with mild to moderate myopia and astigmatism. But to be sure, consult your eye doctor first to determine if you are a good candidate for ortho-k. Factors to consider include the following:

  • The shape and health of your cornea

  • The severity of your refractive error

  • Your overall eye health


Maintenance And Follow-Up Care


Successful ortho-k treatment requires proper maintenance and regular follow-up care. Follow your eye care professional's instructions regarding lens cleaning, storage, and replacement. Regular checkups are necessary. These monitor the progress of your corneal reshaping and ensure proper lens fit.




Ortho-k offers a revolutionary approach to vision correction. It reshapes the cornea and provides clear vision without glasses or daytime contacts. It is nonsurgical, reversible, and has potential myopia control benefits. It is popular among individuals seeking a convenient and effective vision correction solution. 

If you are considering ortho-k, consult with your optometrist at The Eye Place. They will determine if this procedure is right for you and guide you towards enjoying clear, unaided vision.
