Orthokeratology, or Ortho-K, is the temporary reshaping of the cornea with specifically designed and fitted contact lenses for the purpose of improving eyesight. The concept is similar to how an orthodontist uses a dental retainer to straighten crooked teeth. Most Ortho-K lenses are used at night to reshape the front surface of the eye. Nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and sometimes presbyopia can all be corrected using Ortho-K.
Ortho-K is mostly used to treat nearsightedness (myopia). Orthokeratology is a non-surgical option for some people who want to ditch their glasses and avoid wearing contact lenses all the time. This can be a good alternative for the individuals who want LASIK but aren’t ready for surgery.
For correcting eye problems, Ortho-K Lens is suitable for the following people:
Prescriptions in the range of +2.00 to -6.00 with no more than -1.75 diopters of surface astigmatism.
Ortho-K adjusts the cornea’s curve to correct vision problems. The corneal curvature correction is just temporary. The cornea will return to its original shape if
the corneal molds are discontinued.
