Q: Please explain what Ortho-Keratology is and give a basic sense of how it works.
A: Orthokeratology is a procedure using specially designed gas permeable contact lenses to gently reshape the corneal curvature of the eye while sleeping. The lenses are designed to be removed upon awakening and the patient will have great vision throughout the day without the need of daily contact lenses or eyeglasses.
Q: How does the Ortho-K assist in treating nearsightedness, and astigmatism.
A: The way to have clear vision is for light rays that travel through your eye to focus on your retina, orthokeratology does this by gently reshaping the cornea. It's a similar philosophy (changing corneal curvature) as LASIK but orthokeratology does no permanent damage or removal of corneal tissue as with LASIK.
Q: How often should I have my glasses prescription checked?
A: The American Optometric Association recommends yearly eye-health examinations. As part of a comprehensive eye exam your optometrist will not only check your glasses prescription for changes, but he/she will also evaluate your eye health. Every patient needs to be regularly monitored for glaucoma and other diseases. For adults, it’s important to monitor for cataracts and macular degeneration. And certain medical conditions, like diabetes, require yearly eye-health exams as well to monitor the potential side-effects they can have on the eyes. For children, visual dysfunction conditions like “lazy eye” and “crossed eyes,” can be missed with school vision screenings alone. A regular complete eye examination is an integral part of routine health care.
