What is Ortho-K

Orthokeratology, or Ortho K, involves the use of specially designed rigid gas permeable (RGP) contact lenses to improve the vision through the reshaping of the cornea.

In recent years technology has become available to accurately scan the cornea and manufacture lenses that will achieve a controlled and precise reduction in the eye’s optical imperfections. In addition the development of lens materials with higher levels of oxygen permeability have enabled safe overnight wear.

The technique of Ortho K is now a safe, viable and reversible alternative to laser refractive surgery. The cornea is elastic and returns to its original shape if lens wear is stopped. For this reason the lenses are worn nightly or 4-5 nights per week, after the ideal corneal shape has been achieved, and removed in the morning giving perfect vision all day.

Why Ortho-K

The main purpose of Ortho K is to be free of both contact lenses and spectacles all day. The freedom from any artificial aids appeals to spectacle and contact lens wearers. It is ideal for sportsmen, those who work in dusty or dirty environments or people who find spectacles or conventional contact lenses inconvenient.

In addition, 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 ideal situations for using Ortho K is for the child or teenager with early myopia (short sightedness). Not only does it give them the advantages listed above but the procedure appears to also stabilise or retard the progression of myopia.
