Orthokeratology (Ortho-K) is a special process that corrects blurred vision caused by myopia using an overnight contact lens retainer that is removed on waking the next morning. This allows clear vision all day without the need for wearing either contact lenses or glasses.
Ortho-K is ideal for patients who suffer from dryness or irritation when wearing regular soft contact lenses, or work in a very dusty or windy environments. Ortho-K is also suited to certain sports and activities such as swimming, surfing and scuba diving where contact lenses may become dislodged or lost. One of the main benefits of Ortho-K treatment in younger patients is that it can slow down or stop the deterioration inmyopia that occurs as the eyeball grows larger.
