Ortho-K

For many people, clear vision during the day comes with the daily routine of putting on glasses or contact lenses. While effective, these options aren’t always convenient - especially for children, athletes, or adults who prefer a glasses-free lifestyle. At Palo Alto Eyes Optometry, we specialize in fitting custom Ortho-K lenses and guiding patients through the process to ensure safe, effective results.

What Is Ortho-K?

Orthokeratology (Ortho-K) is a non-surgical vision correction method that uses specially designed, rigid gas-permeable lenses worn overnight. While you sleep, these lenses gently reshape the cornea (the clear front surface of your eye). This controlled reshaping corrects how light enters the eye, allowing it to focus properly on the retina.

The result is clear, natural vision during the day without the need for glasses or daytime contact lenses. Unlike surgical procedures such as LASIK, the effects of Ortho-K are temporary and reversible, giving patients flexibility and peace of mind.

How Does Ortho-K Work?

Ortho-K lenses act like a mold for your cornea. By applying gentle, even pressure overnight, they flatten specific areas of the cornea to correct refractive errors like nearsightedness. When the lenses are removed in the morning, the cornea maintains its new shape for hours, giving you clear vision all day.

Myopia Control for Children

The rise in childhood myopia is a growing concern worldwide, particularly as increased screen time and reduced outdoor activity contribute to its progression. Ortho-K is one of the most effective ways to slow this progression.

Clinical research has shown that Ortho-K lenses can significantly reduce the rate at which myopia worsens in children. By slowing the elongation of the eye, Ortho-K helps protect long-term eye health and reduce the risk of future complications, such as:

• Retinal detachment

• Glaucoma

• Cataracts

• Macular degeneration

Parents who choose Ortho-K for their children not only give them clear vision now but also invest in their future eye health.

Ortho-K for Adults

Adults can also benefit from the freedom Ortho-K provides. It’s an excellent option for:

• Athletes who don’t want the hassle of glasses or daytime contacts during activities.

• Professionals who prefer a glasses-free appearance.

• Active individuals who swim, hike, or spend time outdoors.

• Patients not eligible for LASIK or those who prefer a non-surgical solution.

Since Ortho-K is temporary and reversible, it offers flexibility for adults who want vision correction without long-term commitments.

The Ortho-K Fitting Process

At Palo Alto Eyes Optometry, the fitting process is customized for each patient:

• Comprehensive Eye Exam - to evaluate eye health and determine candidacy.

• Corneal Topography - advanced mapping technology measures the shape and curvature of your cornea.

• Custom Lens Design - lenses are tailored specifically to your corneal shape and prescription needs.

• Initial Fitting & Training - patients are taught how to insert, remove, and care for their lenses.

• Follow-Up Visits - to monitor progress, confirm proper fit, and ensure comfort and effectiveness.

This personalized approach ensures the best possible outcomes for both children and adults.

How Long Until the Full Effect Is Achieved?

Most patients notice improvements in their vision within the first few nights of wearing Ortho-K lenses, though complete stabilization often takes several weeks. During this adjustment phase, vision may fluctuate as the cornea gradually reshapes. For some, the changes happen quickly, while others experience a slower progression.

Once the eyes have fully adapted, clinical studies submitted to the FDA showed that more than 65% of wearers achieved 20/20 vision, and over 90% reached 20/40 vision or better - the standard required for driving without corrective lenses in the U.S.
