Ortho-K lenses are designed to be worn while you sleep and should not be painful. As with any contact lens, there may be some initial awareness while adapting to the lenses. Proper fitting, lens care, and regular follow-up appointments are important for comfortable and safe wear.

How long does it take to see results?

Many patients notice an improvement in their vision after the first few nights of wear. The time needed to achieve the desired correction varies depending on factors such as your prescription, corneal shape, and how consistently the lenses are worn.

Do I have to wear Ortho-K lenses every night?

Ortho-K temporarily reshapes the cornea, so continued overnight wear is required to maintain the vision correction. Many patients wear their lenses every night, although the recommended wearing schedule may vary depending on the individual.

Is Ortho-K right for my child?

Ortho-K may be an option for children with progressing myopia. In addition to providing clearer daytime vision without glasses or contact lenses, Ortho-K can help slow the progression of nearsightedness. A comprehensive eye examination and corneal assessment will help determine whether your child is a suitable candidate.

How is Ortho-K different from LASIK?

Unlike LASIK, Ortho-K does not involve surgery or permanently alter the cornea. The lenses temporarily reshape the cornea while you sleep, and the effect gradually diminishes if lens wear is discontinued. This also makes Ortho-K an option for children, who are not candidates for LASIK.

UNDERSTANDING ORTHO-K

What Is Orthokeratology?

Orthokeratology (Ortho-K) uses specially designed contact lenses worn overnight to gently and temporarily reshape the cornea. After removing the lenses in the morning, many patients can enjoy clear vision throughout the day without glasses or daytime contact lenses.

Ortho-K is a non-surgical, reversible option for correcting nearsightedness. For children with progressing myopia, it can also help slow the progression of nearsightedness, supporting long-term eye health.

THE ORTHO-K PROCESS

How Orthokeratology Works

01

Comprehensive Fitting

We map your cornea using advanced imaging to design your custom lenses.

02

Custom Lens Design

Your Ortho-K lenses are manufactured specifically for your prescription and corneal shape, providing an individualized fit.

03

Overnight Wear

Wear your custom Ortho-K lenses while you sleep. The lenses gently and temporarily reshape your cornea overnight, allowing for clearer vision the following day.

04

Clear Daytime Vision

Remove your Ortho-K lenses each morning and enjoy clearer vision throughout the day without glasses or daytime contact lenses.

05

Ongoing Monitoring

Regular follow-up appointments allow us to assess your vision, monitor corneal health, and make adjustments to your lenses as needed to maintain safe, effective treatment.

Maintaining Your Results:

Ortho-K results are temporary and require consistent overnight lens wear. If treatment is discontinued, the cornea gradually returns toward its original shape, and the vision correction effect diminishes.
