OrthoK – Clear vision without vision correction surgery.

Our night-time lenses can help you to have clear vision throughout the day without vision correction surgery.

What is overnight vision correction (orthokeratology)? 

Overnight vision correction (orthokeratology) is a non-surgical treatment which corrects short-sightedness (myopia), farsightedness (hyperopia), and astigmatism. Custom designed overnight contact lenses are worn while you sleep and are then removed each morning, resulting in clear, natural vision all day long.

Perfect Vision all Day & Night

With overnight vision correction (orthoK) you can see while wearing the contact lenses, but just as importantly, when you take them out in the morning your vision will also be clear and crisp.

How does it work?

Short-sightedness (myopia) is effectively when the eyeball is too long. Overnight contact lenses act like a mould to gently flatten the cornea by less than a hair’s width. This is sufficient to alter the angle at which the light enters the eye so that it focuses correctly on the retina rather than in front of it. To maintain this effect the lenses must be worn each night.

Is it Painful?

It may seem like corneal reshaping would be painful, but it’s not. That’s because the reshaping is not the result of squeezing or “squishing.” Instead, it comes from hydraulic forces. The lens forms a vault of fluid over the eye, causing some parts of the cornea to take in more fluid and some parts to takes in less, changing the shape of the cornea and temporarily correcting curvature issues. While orthokeratology usually brings to mind myopia corrections and myopia control, orthok lenses can be designed to visually correct hyperopia and presbyopia as well.

Overnight vision correction gives you all the benefits of laser surgery without the expense and pain.

Who is it ideal for

• Children – it provides daytime clear vision without the fuss of lenses.
• Allergy sufferers – allows glasses free vision, even during hay fever season.
• Sports / Athletes – removes the risk or damaging /losing eyewear whilst engaging in physical activity.
• Dry eye sufferers – avoid the irritation that can sometimes be caused by day time contact lenses.

OrthoK lenses can be effective for almost anyone, but children are particularly good candidates. That’s because laser surgery isn’t suitable for these young patients. However, kids who don’t want to wear glasses often achieve fantastic results with orthoK lenses. We now know that this treatment is one of the most effective methods of slowing down progressive myopia in children and  myopia management. Other good candidates include those within a specified range of prescriptions, and those who need vision correction without corrective lenses, such as pilots, police officers, or athletes.

Why have I not heard of this before?

The science of overnight vision correction or orthoK (orthokeratology) is not new, but it is only in recent years that the technology has allowed for the accurate measurement of the eye to be translated by computer. Once translated, the information can be used to create precise, personalised contact lenses.
