How Ortho-K Controls Myopia Progression?

Orthokeratology, commonly known as Ortho-K, is a specially designed rigid gas permeable contact lens that is worn overnight. The lenses gently reshape the cornea, temporarily eliminate your refractive error so that there is no need for glasses or contact lenses during the day.

How does Ortho-K Correct Myopia?

Myopia (nearsightedness) happens when light focuses in front of the retina. Ortho-K is designed to flatten the cornea in order to focus the light on the retina. The following diagram shows how Ortho-K work:

How does Ortho-K Control Myopia Progression?

When light focuses in front of the retina, this blurriness can send a signal to the brain that the eye is too short and needs to grow longer to bring distant objects into clearer focus, and hence myopia progresses.

Ortho-K’s unique design creates a central area of focus (where the visual correction occurs) while causing peripheral defocus in a way that is opposite from the usual defocus seen in myopia, slowing down the elongation of eyeball.

What are the Benefits of Ortho-K?

Reduce progression of myopia: Studies suggest that Ortho-K may play a role in slowing the progression of myopia in children and adolescents.
Non-surgical: Ortho-K provides a non-surgical alternative to procedures like LASIK, SMILE pro, TransPRK and ICL.
Freedom from daytime correction: People who wear Ortho-K lenses can experience clear vision throughout the day without relying on glasses or contact lenses.
Safe and effective: Ortho-K is safe if correct lens wearing and cleaning is practiced.

Who is an Ideal Candidate for Ortho-K?

Ortho-K is broadly applicable and well-suited for a variety of conditions, providing significant relief and positive outcomes for many individuals. For example:

Children and adolescents
Adults with active lifestyle
Athletes
Alternative approaches to refractive surgery
Myopia
Astigmatism

What You Can Expect from Ortho-K

Patients who start using Ortho-K lenses often see results fairly quickly. While it may take up to two weeks or more to reach full vision correction, some people experience noticeable improvement in just a few days.
