Ortho-K (short for Orthokeratology) is a non-surgical solution for patients with myopia (nearsightedness) that uses specially designed contact lenses (like Paragon CRT® 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 is the first contact lens of its kind to be FDA approved for overnight wear and is a non-surgical, reversible treatment option.
