Ortho K Overnight Vision Correction
Home > Contact Lenses > Ortho K
A safe, viable and reversible alternative to laser refractive surgery.
Orthokeratology, or Ortho K, involves the use of specially designed rigid gas permeable (RGP) contact lenses to alter the shape of the cornea in order to reduce or correct short sight and astigmatism. Most patients wear the lenses overnight and remove them on awakening.
Ortho K provides the opportunity to be free from both contact lenses and spectacles for the waking hours.
The procedure particularly appeals to short-sighted spectacle and contact lens wearers and is ideal for sportsmen, those who work in dusty and dirty environments or people who find spectacles or conventional contact lenses inconvenient.
Those who need to have a certain degree of uncorrected vision to satisfy their employers or a licensing body (e.g. pilots, police) can also be helped by Ortho K. Possibly one of the most ideal situations for using Ortho K is for the child or teenager with early myopia. Apart from the advantages already given, there is new evidence to suggest that the procedure may slow down the progression of myopia.
