CRT, or Corneal Refractive Therapy, is a non-surgical option that helps correct nearsightedness without the daytime use of contacts or glasses. CRT lenses are worn at night, and correct the curvature of the cornea while sleeping so you can see clearly during the day.
THE SCIENCE BEHIND CRT
Ortho-K (short for Orthokeratology) is a non-surgical solution for patients with myopia (nearsightedness) that uses specially designed contact lenses to improve vision.
When worn overnight, Paragon CRT contact lenses gently corrects the curvature of the cornea, resulting in a corneal shape that focuses light correctly onto the retina. When removed in the morning, distant objects will come back into focus and patients can see clearly without the use of glasses or daytime contacts.
PARAGON CRT CONTACT LENSES FIRST FDA APPROVAL FOR OVERNIGHT USE
Our goal is to correct your vision by eliminating daytime use of eyeglasses or contact lenses. In the FDA trials for Paragon CRT contact lenses, more than 90% were able to see 20/40 or better1 (the legal vision requirement for driving without glasses in most states).
