What is Ortho-K?
05/11/2014
Orthokeratology, or Ortho-K is scheduled modification of the cornea, the first lens of the eye, in order to improve vision without optical compensation. The Ortho-k is done with special contact lenses that are used while you sleep and allow clear vision without glasses or contact lenses during the day.
The Ortho-K has its origins in the 60s, when it was discovered that contact lenses modifying corneal curvature and therefore graduation.
For 10 years, new technologies have made it possible to effectively treat myopia higher than at the beginning and progress through corneal topography, design and manufacture of lens geometries impossible before. In this sense, one can still treat farsightedness and astigmatism.
In addition, the use of new materials hyperpermeable oxygen made it possible to use night safely.
Who cares the Ortho-K?
The main objective of Ortho-K is freely see without glasses or contact lenses during the day. Freedom from an optical aid is ideal for sports. All those who work in dusty or dirty are very annoying glasses or contact lenses. Besides all those professions that require good vision without glasses can receive a grant from the Ortho-K.
Control of Myopia
An interesting application is in children or young budding myopia, because not only have advantages but also several previous studies have proven a reduction in the progression of myopia.
Everyone is right for Ortho-K?
The procedure works well in ametropias (Nearsightedness and farsightedness) or not associated with low to moderate to low astigmatism. Top Rankings can be adjusted depending on the characteristics or corneal response of the cornea itself.
There are several factors that force the individual to make an assessment of the viability in each case.

Ortho-K has advantages over refractive surgery?
- It can be performed on thin corneas, when surgery is not possible.
- Helps control the development of myopia.
- The procedure is reversible
- Changes can be adjusted graduation.
- Visual freedom during the day (either glasses or contact lenses).
- Is reversible.
- Is safe.
- You can stop the progression of myopia.
- It can be done at any age.
