Orthokeratology

What is Ortho-K?

Orthokeratology is the use of Contact Lenses to change the shape of the Cornea to reduce or correct Myopic (short-sighted) and Astigmatic (irregular surface) errors of the eye. In some ways this is similar to the use of dental braces by an Orthodontist to straighten crooked teeth. The main difference is that if a tooth position is corrected for some months it will stay in the new position.

The Cornea is highly elastic, however, and always returns to its original shape. For this reason the Contact Lenses are worn nightly, alternate nights or two to three hours each day after the ideal Corneal shape has been achieved.

Why have Ortho-K done?

The main purpose of Ortho-K is to be free of both Contact Lenses and Spectacles for the majority of, or possibly all, waking hours. The freedom from any artificial aid appeals to Myopic Spectacle and Contact Lens wearers and is ideal for sportsmen, swimmers, those who work in dusty or dirty environments or VDU users (dry atmospheres).

This technique is also good for people who have to attain visual standards without spectacles for certain occupations, e.g. Policemen, Firemen and Pilots.

Possibly the ideal situation for using Ortho-K is for the teenager just becoming short-sighted. Not only does it have all the advantages already given above, but the procedure appears to stabilise the progression of the Myopia.
