Does Ortho-K Actually Work? 

November 1 2022

If you’ve ever wanted to get rid of your glasses or contacts and be able to see clearly without them, then Ortho-K may be the solution for you. Ortho-K, also known as orthokeratology, is a non-surgical procedure that uses special contact lenses to gently reshape the surface of the eye. 

In this post, an Old Tapan, NJ optometrist explores what Ortho-K is, how it works, and whether or not it’s right for you.

What Is Ortho-K?

Ortho-K is a non-surgical procedure that reshapes the curvature of your cornea using specially designed contact lenses. These lenses are designed to gently flatten out the steepest part of your cornea. The goal is to reduce or eliminate your need for glasses or contacts by improving how light focuses on your retina.

Eye conditions like nearsightedness, farsightedness, and astigmatism are often caused by an overly curved cornea. When your cornea is curved too much, it can’t focus light on the retina as it should, which results in blurry vision. Ortho-K lenses fix this problem.

How Do Ortho-K Lenses Work?

Orthokeratology uses custom-fit contact lenses to gradually change the shape of your corneas. While there is no doubt that this treatment can be effective, it’s important to understand exactly how it works.

The cornea is the clear outer layer of your eye. It’s responsible for focusing light onto the retina, which then passes images to your brain so that you can see. The curvature (or shape) of your cornea determines how much light enters your eye and where it focuses it. 

For example, if you’re nearsighted, an overly-curved cornea will focus incoming light in front of the retina instead of directly on it. This accounts for why faraway objects appear blurry. Through the overnight effects of Ortho-K, the cornea is restored to a normal shape so light can land directly on the retina as it should.

Who’s a Good Candidate for Orthokeratology?

Ortho-K is a good option for anyone who is looking for a quick and easy way to improve their vision and eliminate the need for glasses or daytime-wear contacts.

If you have any of the following conditions, then Ortho-K may be the right treatment for you:

  • Astigmatism
  • Myopia (nearsightedness)
  • Hyperopia (farsightedness) 
  • If you have trouble wearing contacts or glasses all day long 
  • You work in an environment where it’s not safe to wear contacts or glasses, like construction workers, firefighters, and police officers 
  • Presbyopia (age-related farsightedness)

Ortho-K is a great option for people who are tired of their glasses or contacts. It’s easy, affordable, and safe with no side effects.
