What Is Corneal Refractive Therapy?

Refractive errors, such as nearsightedness, farsightedness, and astigmatism, hamper your vision as well as your overall quality of life if they aren’t properly managed. At Shady Grove Eye and Vision Care, we have a wide range of vision correction options to help you see better. Apart from corrective eyewear and laser eye surgery, we also provide orthokeratology therapy.

We discuss how it works below.

What Is Orthokeratology?

Refractive errors usually develop when corneal infirmities impair the light-bending and focusing process in your eyes. Orthokeratology is a non-surgical solution to correct this problem. It involves wearing ortho k lenses—specially engineered by our eye doctor to reshape your cornea—while you sleep. When you wake up, you can enjoy clear eyesight throughout the day. You’ll need to wear the ortho k lenses every night to see clearly the following day.

In April 2002, the Food and Drug Administration approved the first brand to manufacture ortho k lenses. Paragon Vision Sciences, under federal authority, produced the Paragon Z CRT®, which stands for corneal refractive therapy. FDA trials for CRT revealed more than 90% of the participants were able to achieve 20/40 visual acuity. This means their eyes are sharp enough to drive without having to wear prescription eyewear in most states.

What Are the Benefits of Orthok/CRT?

One great benefit of ortho k therapy is that you’ll experience immediate results. After wearing the CRT lenses for just one night, you’ll wake up to clearer eyesight. The effects can last a whole day without having to use prescription eyewear.

Who Is a Good Candidate?

Ortho k was initially developed to help correct nearsightedness or at least prevent its progression. However, studies also show it is effective at managing other refractive errors, like farsightedness, astigmatism and even presbyopia. It’s a great option for people with active lifestyles.

The best way to know if you’re a good candidate for CRT is to undergo an eye exam. Call us today at (301) 859-4060 or complete our form to schedule an appointment. We serve residents in Washington, DC, Alexandria, VA, and Rockville, MD.
