What is CRT?
CRT (short for corneal refractive therapy) is a nonsurgical procedure using specially designed contact lenses to gently reshape the curvature of the eye to improve vision.

CRT is also known as orthokeratology, or OrthoK.
How CRT works
Who is a good candidate for CRT?
If you are one of the billions of people in the world who are nearsighted and you want the freedom from your daytime contacts or glasses then CRT may be a great option for you! If you’re one of the many individuals who experience dry eye or contact lens discomfort, CRT may be the treatment option for you. In fact, many successful CRT patients were previous soft lens wearers. If you experience dry eye, LASIK may not be an appropriate option, making CRT an excellent alternative. It temporarily eliminates the need for daytime contacts or glasses and is a nonsurgical alternative for patients who prefer a less permanent treatment option. Those with less than -6.00 diopters of nearsightedness and less than -1.50 diopters of astigmatism would be considered good candidates.
