No. Most patients feel little to nothing once the lenses are in, and any initial awareness typically fades within the first few nights.

How long until I see results?

Many patients notice improved vision within the first day or two, with full results typically achieved within one to two weeks of consistent nightly wear.

Do I have to wear the lenses every night forever?

To maintain clear vision, yes — consistent nightly wear is needed, since the cornea gradually returns to its original shape without it. Many patients find every-other-night wear works for maintenance once the initial reshaping is complete, though this varies by individual.

Is ortho-k right for my child?

Ortho-k is one of the most well-studied approaches to childhood myopia control. We'll evaluate your child's prescription, eye health, and lifestyle during a consultation to determine if it's a good fit.

How is this different from LASIK?

Ortho-k is non-surgical and fully reversible — nothing is permanently altered. LASIK is a permanent surgical procedure. Ortho-k is a good option for patients who aren't candidates for or aren't ready for surgery, including children (who aren't LASIK candidates at all).

Orthokeratology (Ortho-K): Clear Vision While You Sleep

Wake up to clear vision — no glasses, no daytime contacts. Primaris Vision's ortho-k program reshapes your cornea overnight and helps slow the progression of myopia in children and adults.

Who Is Ortho-K For?

Ortho-k is a great option for:

Children and teens with progressive myopia — one of the few clinically supported ways to help slow the worsening of nearsightedness during the school-age years.
Adults who want glasses- or contact-free days without pursuing LASIK or other refractive surgery.
Athletes and active individuals who find glasses or daytime contacts inconvenient for sports or outdoor activity.
People with dry eyes or dusty/dry work environments who struggle with daytime contact lens wear.
Anyone with mild to moderate myopia (nearsightedness), and in some cases mild astigmatism, who isn't ready for or a candidate for LASIK.

A comprehensive eye exam and corneal evaluation at Primaris Vision will confirm whether you or your child are good candidates.

Why Choose Ortho-K?

Non-surgical and fully reversible — unlike LASIK, there's no permanent alteration to your eye.
Freedom from daytime glasses and contacts — ideal for sports, work, and everyday convenience.
Myopia control for kids — helps slow the progression of nearsightedness, which may reduce long-term risk of complications associated with high myopia later in life.
Custom-fit for your eyes — every lens is designed specifically for your corneal shape and prescription.
FDA-cleared technology, backed by decades of clinical use.

Frequently asked questions

Orthokeratology

How It Works

Comprehensive fitting exam. We map the precise shape of your cornea using advanced imaging to design lenses custom-fit to your eyes.
Custom lenses are made. Your ortho-k lenses are manufactured specifically for your prescription and corneal shape — no two fittings are the same.
Wear them overnight. You sleep in the lenses each night. While you rest, they gently reshape your cornea's curvature.
Wake up and see clearly. Remove the lenses in the morning and enjoy clear vision throughout the day — no glasses or daytime contacts needed.
Ongoing check-ins. We monitor your eyes and adjust your lenses as needed to keep your vision sharp and your eyes healthy.

Results are temporary and require consistent nightly wear to maintain — but that also means the effects are fully reversible if you ever choose to stop.

What Is Orthokeratology?

Orthokeratology — or ortho-k — uses specially designed, custom-fitted contact lenses worn only while you sleep. As you rest, the lenses gently and temporarily reshape the surface of your cornea, so when you wake up and remove them, you see clearly all day without glasses or daytime contacts.

It's a non-surgical, fully reversible alternative to LASIK — and for children and teens, it's one of the most effective tools available to help slow the progression of myopia (nearsightedness).
