Ortho-k for myopia

Ortho-k contact lenses are used to treat myopia. Worn at night, they gently correct the shape of the eye to give clear distance vision.

What is ortho-k?

Ortho-k (clinically known as orthokeratology) uses bespoke contact lenses to treat myopia (short-sightedness). These contact lenses temporarily reshape the front surface of the eye, so correcting vision.

Ortho-k contact lenses are usually worn overnight. While asleep they gently correct the shape of the cornea. Next morning the orthot-k lenses are taken out, leaving the patient with clear distance vision.

Treatment using ortho-k lenses is non-invasive (no surgery) and completely reversible. It is suitable for both children and adults, although it is most effective for children who have myopia.

About myopia ortho-k contact lenses

Benefits of treating myopia with ortho-k lenses

Another benefit of ortho-k is that it is one of the most effective treatments for myopia. Studies have show that wearing the lenses reduces the progression of myopia in children, teenagers and young adults.

Ortho-k offers freedom from glasses and the hassle of wearing contact lenses during the day. It is also a great option anytime glasses or contact lenses become a nuisance, like when swimming, playing sport, or when working in dusty environments.

In addition, beacuse patients no longer need to wear contact lenses during the day they experience less eye irritation and dry-eye.
