Orthokeratology reshapes your cornea while you sleep. For the right patients — especially kids with progressing myopia — it's a game changer.
Orthokeratology, or ortho-k, uses specially designed rigid lenses worn while sleeping. The lenses gently reshape the front surface of the eye overnight so many patients can see clearly during the day without glasses or daytime contact lenses.
For children with progressing myopia, ortho-k may offer two benefits: daytime freedom from correction and a myopia-management effect that can help slow prescription changes. It is also popular with athletes, swimmers, and people who work in dusty or dry environments where daytime contacts are inconvenient.
How ortho-k works
The cornea is flexible enough to be gently reshaped by a custom lens, but the effect is temporary. That is why lenses are worn regularly overnight. When fit properly and cared for correctly, the treatment can provide clear functional vision throughout the next day.
Ortho-k is highly customized. The safety and clarity of the result depend on careful measurements, lens design, training, and follow-up.
Who may be a good candidate
- Children or teens with progressing nearsightedness
- Active patients who dislike glasses during sports
- People who struggle with daytime contact lens dryness
- Patients with prescriptions within a treatable range
- Families willing to follow cleaning and follow-up routines
What to expect during fitting
The process begins with corneal topography, prescription testing, eye health evaluation, and a detailed conversation about goals. After lenses are designed, we teach insertion, removal, cleaning, and overnight wear routines. Early follow-up visits are important because we need to confirm the cornea is responding as expected.
Vision often improves quickly, but it may take several nights or lens adjustments to reach the best result. We monitor comfort, corneal health, lens positioning, and visual stability over time.
Safety comes from consistency
Like any contact lens, ortho-k requires excellent hygiene. Lenses should be cleaned exactly as instructed, never rinsed with tap water, and replaced on schedule. With responsible care and regular monitoring, ortho-k can be an excellent option for the right patient.
