Benefits Ortho-K is not only an excellent alternative to the wearing of spectacles, but it also frees the individual from the distractions caused by perspiration, dust, wind weather and temperature. There are no more blind spots caused by frame or lens edges. Ortho-K might open new horizons to you. The Ortho-K specialist measures the curvature of your cornea using the corneal topographer. It is like having your picture taken and is painless, taking about five minute.
Some doctors also use software to help design the lenses.
Diagnostic lenses will be placed on your eyes to help determine the proper lens. Contact lenses for Ortho-K have a reverse geometry design. The reverse geometry part of the lens surrounds the central visual zone and is further away from the cornea than standard lenses allowing room for the shift of epithelium. If your doctor prescribes overnight Ortho-K, expect results immediately. Your vision should be markedly improved after the first night.
