What Is Ortho-K?

A Better Way
to See the World

Orthokeratology, often referred to as Ortho-K or corneal reshaping therapy, is a specialized non-surgical technique designed to correct refractive errors of the eye, including myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

Unlike traditional glasses or daytime contact lenses, orthokeratology uses specially designed rigid gas-permeable contact lenses worn overnight. While you sleep, the lenses gently and temporarily reshape the cornea to provide clearer vision during the day without traditional corrective lenses.

How Ortho-K Works

Specialized gas-permeable lenses are inserted at bedtime and worn while you sleep. Throughout the night, the lenses gently reshape the cornea so that vision becomes clearer the following morning.

The correction is temporary. Ideally, glasses or daytime contact lenses will not be needed the following day. To maintain sharp visual acuity consistently, Ortho-K reshaping lenses generally need to be worn each night as directed by your eye doctor.

SPECIALIZED ORTHO-K CARE

Dr. Viet Tran specializes in orthokeratology care and has successfully treated patients of different ages to help reduce dependence on daytime glasses or contact lenses and to help manage myopia in young children.

Key Aspects of Orthokeratology

Customized Fitting

Every patient's eyes are unique. Our office uses advanced computerized corneal mapping and measurement techniques to design Ortho-K lenses specifically for each patient's eyes.

Temporary & Reversible Effect

The corneal reshaping achieved through orthokeratology is temporary. The effect can provide clear daytime vision, but the cornea gradually returns toward its original shape when lens wear is discontinued.

Myopia Control

Ortho-K has gained attention as both a vision correction method and an option for managing progression of myopia, especially in children and teenagers.

Non-Surgical & Non-Invasive

Orthokeratology does not involve incisions or removal of eye tissue. Because corneal reshaping is temporary, treatment is reversible.

Candidacy & Monitoring

A comprehensive eye examination and detailed corneal measurements are necessary to determine whether your eyes are suitable for Ortho-K. Regular follow-up appointments are important.

Advantages & Considerations

Ortho-K may be convenient for active children and adults. Successful treatment requires proper lens cleaning, disinfection, storage, and wear according to your doctor's instructions.

Vision Results From Orthokeratology

Results with Ortho-K vary depending on the patient's prescription, corneal shape, treatment response, and other individual factors.

Improvement in vision may occur within the first few nights of treatment, although the full effect can take longer. During the adjustment period, vision may fluctuate and some patients may notice glare or halos around lights.

Your eye doctor will monitor your progress and determine whether your vision prescription, corneal shape, and overall eye health make you a good candidate for treatment.

Risks & Side Effects

Orthokeratology is generally considered safe when the lenses are properly fitted, cared for, and used under professional supervision. However, as with other contact-lens wear, complications are possible.

Improper lens hygiene, wearing lenses longer than directed, or continuing to wear lenses despite pain, redness, or significant discomfort can increase the risk of eye infections, corneal ulcers, and other complications.

Cleaning and disinfecting the lenses as instructed, following the recommended wearing schedule, and attending regular follow-up appointments are important parts of safe Ortho-K treatment.

If you experience unusual pain, persistent redness, sensitivity to light, discharge, or a sudden change in vision, discontinue lens wear and contact your eye doctor promptly.
