People with nearsightedness & astigmatism have traditionally needed to depend on glasses & contact lenses to obtain clear vision to perform important daily tasks. Recent developments in refractive surgeries such as LASIK have allowed many people to have improved vision. But this is not always appropriate for everyone. To be a candidate for surgical treatment, a person should have a history of stable prescription changes for several years, and be a minimum of 18 years of age.
Now, there is an alternative that can offer reduced dependence or complete freedom from glasses and contact lenses during waking hours, without the need for surgery & its potential side effects. Ortho-K (Orthokeratology or Gentle Corneal Molding), and is achieved with very specialized contact lenses, which cause precise, predictable changes in the optical surface of the eye, resulting in correction of vision defects. The technique is comfortable & reversible, unlike surgical methods. You also do not have to be 18 years of age or older to start!
Many people are able to wear Ortho-K contacts while sleeping and remove the lenses when awake, and have good vision. As time passes the memory of the corneal shape change is enhanced and the correction lasts longer into the day. It is not uncommon for a person to have good vision through the entire day, without changes.
