Ortho-K Overnight Lenses: Non-Surgical Vision Correction Explained

If you’re looking for freedom from glasses or daytime contact lenses - but aren’t ready for LASIK - Orthokeratology, commonly known as Ortho-K, may be the solution. At CU Vision, we offer Ortho-K overnight lenses as a safe, non-surgical option for correcting vision while you sleep.

What Is Ortho-K?

Orthokeratology (Ortho-K) uses specially designed, gas-permeable contact lenses worn overnight to gently reshape the surface of the eye (the cornea). While you sleep, the lenses temporarily adjust the curvature of your cornea so that light focuses properly on the retina. When you remove the lenses in the morning, you can see clearly throughout the day - without glasses or contacts.

How Does Ortho-K Correct Vision?

Ortho-K lenses work by applying precise, controlled pressure to the cornea. This reshaping changes how light enters the eye, correcting refractive errors such as nearsightedness (myopia). Because the cornea is flexible, it can be safely reshaped in a reversible way. If you stop wearing the lenses, your cornea gradually returns to its original shape.

Who Is a Good Candidate for Ortho-K?

Ortho-K may be a great option for:

• Children and teens with progressive myopia
• Adults who are not candidates for laser vision correction
• Individuals with active lifestyles or jobs where glasses and daytime contacts are inconvenient
• Patients who want a non-surgical vision correction option

Many parents choose Ortho-K for their children because it not only corrects vision but may also help slow the progression of myopia. A comprehensive eye exam and corneal measurements at CU Vision will determine whether Ortho-K is right for you or your child.

What to Expect with Ortho-K Treatment

• Detailed Eye Evaluation: Your visit begins with advanced measurements of your cornea and a full assessment of your vision needs. These measurements allow us to design lenses customized specifically for your eyes.
• Custom Lens Fitting: Your lenses are made to fit the exact shape of your cornea. You’ll receive instructions on how to insert, remove, and care for your lenses properly.
• Overnight Wear: You wear the lenses while sleeping. Most patients notice improved vision within the first few days, with optimal results typically achieved within one to two weeks.
• Follow-Up Visits: Regular follow-ups ensure your eyes remain healthy and your vision correction stays on track.

Benefits of Ortho-K

Ortho-K offers several advantages:

• Clear daytime vision without glasses or contacts
• Non-surgical and reversible
• Ideal for active lifestyles and sports
• May help slow myopia progression in children
• Safe for long-term use when monitored by an eye care professional

Because the lenses are worn only at night, many patients appreciate the convenience and freedom they provide during the day.
