What is Corneal Refractive Therapy?

Corneal Refractive Therapy is a non-surgical treatment that uses special contact lenses to reshape the cornea of the eye while you sleep, without altering the physiology of the eye. The result is clearer vision when you wake up that lasts throughout the day.

How does CRT work?

While the theory behind Corneal Refractive Therapy has been around since the early 1940s, the treatment became possible only a few decades ago when computers began to be able to map the cornea and advanced manufacturing allowed for the development of oxygen permeable contact materials. Those who are nearsighted suffer from blurriness caused by light focus in the front of the retina. The CRT lenses are able to safely reshape the cornea, flattening it so light focuses on the retina and the blurriness diminishes.

Who can benefit from CRT?

Unfortunately not everyone is a candidate for CRT lenses. Only those individuals who have low to moderate nearsightedness (with or without astigmatism) can benefit from CRT treatment at this time. If you are curious about benefitting from this FDA-approved vision treatment, contact our Lake Worth eye doctor, Dr. Hetel Bhakta today to schedule your comprehensive eye exam.

Is CRT Safe?

CRT was approved by the Federal Drug Administration in 2002 and has been approved for use in all ages of patients. While there have been no serious adverse risks related to wearing CRT lenses, those who have trouble using contacts should discuss their concerns with their eye doctor before proceeding with treatment.

How long does it take to see results with CRT?

While the majority of patients can begin to notice positive changes in vision within the first few days of treatment, full results can take anywhere from 10 to 14 days. Patients should note that discontinuing nightly wear of the lenses can cause vision to return to its original state in as little as a few days.

How long do the lenses last?

Dr. Hetel Bhakta recommends replacing your CRT lenses once a year. During your visit to our Lake Worth eye care office, our eye doctors and orthokeratology experts will discuss with you the proper care techniques for your lenses so that they will last as long as possible.
