Orthokeratology is the science of correcting your refractive error while you sleep so that you don't need your glasses for the next day. These contact lenses are worn overnight and removed the next morning, providing clear vision for the rest of the day. It's a safe alternative to conventional contact lenses, LASIK, and glasses. Children are especially good candidates for orthokeratology. Studies from around the world have indicated that Ortho-K can keep your children's nearsightedness from getting worse. Currently, an ongoing 5 year FDA study is seeking to confirm previous studies and prove anecdotal evidence to this fact. Increasing nearsightedness is also a risk factor for detached retina and glaucoma. Your child is an especially good candidate if they have a tendency to lose or abuse their contact lenses/glasses, or if wearing them interferes with their active life.
