Ortho-K (Orthokeratology) uses custom made contact lenses to gently mould your eyes whilst you sleep.

It is a safe alternative to glasses, contact lenses and even laser eye surgery.

A similar concept to braces on your teeth, the lenses act as a retainer, correcting your vision by gently shaping the cornea. When you wake up and remove the contact lenses, the eye is able to hold the corrected shape for up to 16 hours, giving you clear vision all day, without glasses.

Who can use Ortho-K lenses?

Ortho-K suits those who want freedom from glasses or contact lenses during the day. Ideal for those who: 

  • Play sports, particularly contact, snow and water sports
  • Have difficulty with conventional contact lenses due to dry eye, allergies or being in hazardous conditions such as building sites
  • Need glasses just for reading
  • Suffer from myopia. Ortho-K can help slow the progression of shortsightedness in children, teenagers and young adults.

Ortho-K FAQs

Do they hurt?

No. They are a little uncomfortable when first starting to wear them, as if a pressure on the front of the eye (which there is!), but on the closed eye environment they are very tolerable.  Better yet, there is no daytime discomfort because you don't have to wear contact lenses during the day.

How long do a set of Ortho-K lenses last?

Manufacturers suggest annual replacement of lenses, but with good care including a monthly protein clean Ortho-K lenses can last 12-24 months.

Can you see through the Ortho-K contact lenses? 

Yes you can. Some people find it comfortable enough to read in them before sleep.

Do you have to wear them every night?

Ideally yes to retain the shape of the cornea and maintain corrected vision. Now and again, a night off the lenses is okay but expect your vision to start returning to baseline, your pre Ortho-K treatment vision, by the following morning.
