Orthokeratology (ortho-k) is an innovative vision correction method used to treat refractive errors. It’s a great solution for people who don’t like the inconvenience of wearing traditional contact lenses or eyeglasses, yet aren’t willing or able to undergo LASIK.

The Experts Answer Your Top Ortho-K Questions

In today’s post, your expert eye doctor answers commonly asked questions about ortho-k.

Q: What Is Orthokeratology?

Orthokeratology is a non-surgical way to correct myopia and other refractive errors. It involves wearing special contact lenses overnight that temporarily reshape your eyes to eliminate the structural irregularities causing your refractive error. When you wake up the next morning, you can enjoy clear eyesight throughout the day.

Q: How Does It Work?

Ortho-k lenses look just like regular contact lenses. Unlike regular contacts, however, you only need to wear them at night. While you sleep, the ortho-k lenses gently reshape your cornea. When you wake up, you may remove the ortho-k lenses and enjoy improved visual acuity.

Q: What Is the Difference Between Ortho-k, CRT, and VST?

Currently, there are two Food and Drug Administration-approved brands of ortho-k lenses: CRT and VST. Paragon Z Corneal Refractive Therapy (CRT) was approved in April 2002. Bausch and Lomb then released ortho-k lenses, Vision Shaping Treatment (VST), in December 2004.

Q: What Vision Problems Can Ortho-K Manage?

Ortho-k was initially developed to control myopia. Researchers then found that it can also help manage hyperopia, astigmatism and presbyopia.

Q: What Are the Perks of Ortho-K?

With Ortho-k, you can expect fast results and unmatched convenience. After wearing the lenses overnight, you can immediately wake up to sharper vision the next day. You won’t need to wear any corrective eyewear during the day, making ortho-k a great option for athletes and people with active lifestyles.
