Would you like to see clearer without glasses or contacts and without having to undergo eye surgery? Corneal Refractive Therapy (CRT) or orthokeratology is an FDA-approved technology that can help provide those with nearsightedness better vision through the temporary reshaping of the cornea.

This is achieved by wearing contact lenses while you sleep that gently change the shape of the cornea, alleviating the blurred vision associated with myopia. Once the contacts are removed in the morning, the wearer experiences clearer vision throughout the day unaided by glasses or contacts.

Those who start CRT may begin to notice better vision in as little as just a few days, however, most patients will want to allow up to two weeks to gain the full results of treatment. It is important to note that the results of CRT are reversible and will only remain as long as the wearer continues nightly use of the contact lenses.

CRT is a perfect solution for individuals who have mild to moderate nearsightedness, may not be candidates for LASIK surgery, or who do not want to undergo a surgical procedure to correct their vision. Patients who are active and wish to have sharper vision without having to worry about the daily use of glasses or contacts during the day, have found CRT an ideal solution.

Dr. Hetel Bhakta at Planet Vision Eyecare can discuss whether CRT is appropriate for you. If you like the idea of waking up each morning with clearer vision without having to wear glasses or contacts during the day, call our Lake Worth eye doctor and find out more about how you can safely correct your vision – all while you sleep!

CTR – FAQs

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.
