CRT – Frequently Asked Questions

What is Corneal Refractive Therapy?

Corneal Refractive Therapy, or CRT, is an FDA-approved treatment, which requires patients to wear therapy contacts during the night that work to reshape the cornea. After overnight wear of the therapy contacts, patients awake to clearer vision without the use of glasses or daytime contacts.

How does Corneal Refractive Therapy Work?

Special lenses worn during the night reshape the cornea of CRT patients. Those who suffer from nearsightedness experience blurriness because of the way the light is abnormally focused in their retina. The special CRT contact lenses allow light to focus on the retina by flattening the cornea. The results are clearer vision after immediate wear.

Who is the best candidate for Corneal Refractive Therapy?

To learn whether CRT is right for you, call to make an appointment with your Greenacres eye doctor for a full eye exam. Generally speaking however, those who are good candidates for CRT include:

  • Adults, teens and tweens who have mild to moderate nearsighted correction
  • Those who do not qualify, nor wish to undergo LASIK eye surgery
  • Those who lead an active lifestyle and are hampered by wearing glasses or contacts.

Call Planet Vision Eyecare today to schedule an appointment with an optometrist to see if CRT might be right for you.

Is This Treatment Safe?

Optometrists have been successfully helping patients achieve clearer vision through Corneal Refractive Therapy for more than a decade. In 2002 the US Food and Drug Administration approved the use of CRT in patients of all ages. Patients who undergo CRT should be comfortable putting in contact lenses.

How Long Does it Take To Work?

Patients who undergo CRT have reported clearer vision after just a few days of treatment, however, for best results, individuals should allow up to two weeks of nighttime wear of the contacts. Conversely, those who discontinue wearing the contacts will notice a return of their blurred vision after just a few days as CRT is not a permanent corrective solution.

When do The Contacts Need to Be Replaced?

CRT Lenses are typically replaced annually. When you schedule your eye exam at Planet Vision Eyecare, our experienced eye doctor can discuss techniques for proper care of your lenses to ensure the maximum length of use.
