Ortho-K (Orthokeratology)

Nighttime Lenses That Gently Reshape Vision and Slow Myopia

Ortho-K, short for orthokeratology, is a non-surgical treatment that uses custom-designed rigid gas-permeable contact lenses worn overnight to gently reshape the cornea (the front surface of the eye).

In the morning, your child wakes up with clear vision—no glasses or daytime contact lenses needed—and ongoing protection against worsening myopia.

How Ortho-K Controls Myopia:

Myopia (nearsightedness) occurs when the eye grows too long, causing blurred distance vision. Ortho-K lenses correct vision by flattening the central cornea while also creating a special optical pattern that sends “stop signals” to the eye.

Corneal Reshaping: Overnight, the lenses reshape the front of the eye so light focuses correctly on the retina, allowing for clear vision all day.

Peripheral Defocus: Ortho-K lenses redirect light to create peripheral defocus—a scientifically backed method shown to slow down the abnormal elongation of the eye.

Custom-Fit for Each Child: Lenses are individually designed based on precise corneal topography, ensuring a safe and comfortable fit.

Clinically Proven Results:

Studies show that children wearing Ortho-K lenses experience 40%–60% slower myopia progression compared to those wearing glasses or regular contacts. Ortho-K is one of the most well-researched and widely used myopia control methods worldwide.
