What Is Ortho-K and How Does It Work?

Orthokeratology, often called Ortho-K, is a specialized contact lens treatment used for vision correction and myopia management.

Ortho-K lenses are worn overnight while sleeping. During the night, the lenses gently reshape the surface of the cornea.

When the lenses are removed in the morning, many patients can see clearly throughout the day without glasses or contact lenses.

The effect of Ortho-K is temporary and reversible. To maintain clear vision, the lenses must be worn regularly at night.

Ortho-K is often recommended for:

• children with progressing myopia

• active individuals who prefer not to wear glasses during sports

• patients who dislike daytime contact lenses

• adults who want clear vision without daytime correction

Orthokeratology is also widely used as a myopia management treatment, helping slow myopia progression in many children.
