Ortho-K

What Is Orthokeratology,
Ortho-K?

Orthokeratology, often called Ortho-K, is a non-surgical vision correction method that uses specially designed contact lens molds worn overnight. These molds gently reshape the front surface of the eye while your child sleeps. After the molds are removed in the morning, the reshaping effect provides comfortable vision that lasts throughout the day, without the need for glasses or daytime contact lenses.

Where Did the Name Come From?

The term orthokeratology comes from Greek:

ortho, meaning straight or correct

kerato, meaning cornea

logy, meaning the study or practice

Together, the word means the practice of correcting the shape of the cornea. This reflects what the contact lens molds do: gently adjusting the front surface of the eye to improve vision.

How Ortho-K Helps Slow Myopia Progression

Research shows that wearing Ortho-K contact lens molds each night can significantly slow the progression of myopia. The reshaping effect creates a specific optical profile on the eye’s surface that reduces the signals encouraging the eye to grow longer, which is the main cause of increasing nearsightedness.

We offer several advanced Ortho-K designs, including CRT, Euclid, and our doctor’s own custom Ortho-K design. This allows us to tailor the fit and treatment approach to your child’s individual prescription, eye shape, and visual needs.
