What is Corneal Refractive Therapy (CRT)?Paragon CRT (Paragon Vision Sciences) is a specific brand of corneal reshaping lenses that has a proprietary lens design and fitting methodology, called corneal refractive therapy (CRT).
Though technically different than orthokeratology, CRT is used for similar purposes and produces comparable results. For simplicity, I'll be using the terms "orthokeratology" and "ortho-k" to describe all types of corneal reshaping lenses — including corneal refractive therapy lenses — in this article. Your eye doctor will determine which type of corneal reshaping lenses are best for you after examining your eyes. |
