Orthokeratology: Correcting Vision While You Sleep

Personalized treatment with night lenses for temporary myopia correction and progression control.

An innovative technique

Orthokeratology

Orthokeratology is a non-surgical technique that uses rigid gas-permeable contact lenses worn overnight, capable of temporarily reshaping the curvature of the cornea. Upon waking, vision is clear throughout the day without the need for glasses or contact lenses.

Orthokeratology (Ortho-K) is an innovative, non-surgical technique that corrects vision defects such as myopia, astigmatism, and hyperopia during sleep by wearing specially designed, custom rigid gas-permeable contact lenses.

While you sleep, these lenses gently reshape the front surface of the cornea, temporarily correcting the refractive error. Upon waking and removing the lenses, you will see clearly throughout the day without needing glasses or contact lenses.

Ideal for mild to moderate myopia, Ortho-K is especially recommended for children and adolescents, helping to slow the progression of myopia during growth.

Ortho - K

How does it work?

.

What to know

Ortho-K is suitable for:

  • Myopia up to approximately -6.00 diopters
  • Mild hyperopia
  • Astigmatism with low values
  • Children and adolescents: particularly useful to slow down myopia progression
  • People who cannot or do not want to undergo refractive surgery
  • Athletes or those with daily activities incompatible with traditional glasses and contact lenses








Main Advantages

✔ Natural vision during the day without the use of visual aids
✔ Removable and reversible: the cornea returns to its original shape if lens use is discontinued
✔ Myopia control in children, with specific protocols
✔ Nighttime comfort: lenses are worn during sleep and do not interfere with daily life
✔ No surgical intervention: safe, gradual treatment supervised by professionals

The process

✔ Personalized initial assessment: optometric examination and corneal mapping (topography)
✔ Custom lens design tailored to the shape of your eye
✔ Fitting and adaptation with instructions for use, cleaning, and maintenance
✔ Regular check-ups to monitor results and optimize effectiveness

Pediatric Contact Lenses

At Ilop Optical Centers, we offer a highly personalized pediatric contact lens program, in collaboration with ophthalmologists and orthoptists, to ensure maximum safety, comfort, and visual quality.

📍 A solution to slow the progression of myopia.

Is the effect permanent?

No, the effect is temporary and reversible. Vision returns to normal if lens use is discontinued.

The lenses are worn during sleep and, after a short adjustment period, are generally comfortable.

Yes, under professional supervision. Ortho-K is today one of the most effective solutions to control myopia in young people.
