Orthokeratology, or “ortho-k,” is the process of reshaping the eye with specially-designed rigid gas permeable contact lenses. The goal of ortho-k is to flatten the front surface of the eye and thereby correct mild to moderate amounts of nearsightedness and astigmatism. Many people prefer to avoid surgery if possible. However, if you are looking to improve your vision as dramatically as surgery would, you may be interested in orthokeratology, commonly known as “ortho-k”.
