Orthokeratology FAQs

If you or your children suffer from refractive errors, you may be wondering about a treatment called orthokeratology, also known as ortho-k. Ortho-k eliminates your need for glasses to see clearly. Our team at Lewis County Eye & Vision in Chehalis has gathered a few frequently asked questions that we run into from our patients regarding ortho-k.

What is orthokeratology (ortho-k)?

Ortho-k is a noninvasive procedure that involves wearing custom-designed contact lenses to reshape the curvature of your eye and improve your vision. These therapeutic contact lenses are worn only at night while you sleep. When you awaken and remove the lenses, your vision will be improved throughout the day. Over time, you will be able to see clearly without the use of contacts or glasses during the day.

Who is a candidate for ortho-k treatment?

There are no age restrictions for ortho-k therapy. Our eye care specialist in Chehalis will administer a comprehensive eye exam and determine if ortho-k is right for you.

How long will it take for optimal vision using ortho-k?

Most patients show vision improvements within a few days of wearing ortho-k contacts. However, it may take up to two weeks before you enjoy optimal vision. Our eye care specialist will provide you with temporary soft contacts to compensate for a lack of clarity in your vision during this period.

Is ortho-k corneal reshaping therapy permanent?

You will only enjoy improved vision as long as you continue the therapy. If you decide to stop wearing the ortho-k contacts at night, your vision will return to its former state within a few days.

What vision problems can ortho-k correct?

Ortho-k treatments are especially effective for correcting problems with myopia in children. However, it can also be used for teens and adults who suffer from nearsightedness, farsightedness, astigmatism, and presbyopia.
