Ortho-K Lenses: How They Work and Expected Results

If you’re looking for a way to see clearly without wearing glasses or contact lenses during the day, Ortho-K lenses may be an option worth exploring. At My Family Eye Care, we often recommend orthokeratology (commonly called Ortho-K) for patients who want freedom from daytime vision correction or are concerned about progressive nearsightedness.

What Are Ortho-K Lenses?

Ortho-K lenses are specially designed, rigid gas-permeable contact lenses worn overnight. While you sleep, the lenses gently reshape the surface of the cornea - the clear, front part of the eye. This temporary reshaping allows light to focus properly on the retina, so you can see clearly the next day without glasses or contact lenses.

Unlike traditional contact lenses that correct vision while they’re worn, Ortho-K lenses work behind the scenes. You remove them in the morning, and the visual correction lasts throughout the day.

How Do Ortho-K Lenses Work?

The cornea plays a major role in focusing light. In people with nearsightedness (myopia), the cornea’s shape causes light to focus in front of the retina rather than directly on it. Ortho-K lenses are custom-designed to gently flatten the central cornea and adjust its curvature overnight.

Here’s a simple breakdown of the process:

• Custom fitting: Your eye doctor takes detailed measurements of your eyes using advanced corneal mapping technology.

• Overnight wear: You wear the lenses while sleeping, allowing them to gradually reshape the cornea.

• Daytime clarity: In the morning, you remove the lenses and enjoy clear vision during the day.

• Ongoing maintenance: To maintain results, the lenses must be worn consistently each night.

Because the reshaping effect is temporary, Ortho-K requires ongoing use. If you stop wearing the lenses, the cornea will gradually return to its original shape.

Who Is a Good Candidate for Ortho-K?

Ortho-K lenses are commonly used for:

• Children and teens with myopia, especially those experiencing worsening nearsightedness

• Adults with mild to moderate myopia who want a non-surgical alternative to LASIK

• Active individuals or athletes who prefer not to wear glasses or daytime contacts

• Patients with dry eye symptoms who struggle with soft contact lenses

Your eye doctor will determine candidacy based on factors such as prescription strength, corneal health, lifestyle, and overall eye health.

Expected Results and Timeline

Most patients begin noticing improved vision within the first few days of wearing Ortho-K lenses. For some, functional vision may be achieved after just one night, while others may need one to two weeks to reach optimal clarity.

Typical results include:

• Clear vision throughout the day without glasses or contacts

• Stable vision when lenses are worn consistently

• Reduced dependence on daytime vision correction

For children, an additional benefit is myopia management. Research shows that Ortho-K can slow the progression of nearsightedness, which may help reduce the risk of future eye health complications associated with high myopia.
