ORTHo-K OVERNIGHT CONTACT LENSES
Otherwise known as orthokeratology, orthok are a form of overnight contact lenses that help to reshape the cornea, through moulding the surface of the eye at night. Ortho k lenses are a great solution to a non-surgical option for people who experience the struggles of myopia / short sightedness.
Ortho-k lenses help people with short sightedness / myopia to see clearly in the daytime without the use of prescription glasses or contact lenses. Orthokeratology is a very common choice of treatment used to help children showing the early signs of myopia / short sightedness. Evidence has shown that wearing ortho-k lenses overnight helps to reduce the impact of myopia / short sightedness and long term eyesight problems which can begin early in childhood.
Fortunately, when myopia / short sightedness begins in childhood, the signs are usually fairly obvious. For example, a child’s caregivers may begin to notice that the child is struggling with activities such as watching television from a normal distance, or they may be wincing at things ahead, unable to see things like words written upon a blackboard from a distance.
When such struggles with short sightedness begin to occur, it may start to become noticeable that the child’s academic performance is slowly on the decline. When something like this becomes evident, it is important to visit an optometrist immediately for a comprehensive examination. If myopia / short sightedness is the root cause of this issue, making the use of early interventions such as orthokeratology / orthok lenses is an essential to prevent long term eye sight problems.
WHAT IS ORTHO-K?
Orthokeratology is a non-surgical treatment that uses specially designed contact lenses to help address myopia, astigmatism and other refractive errors. This is also called corneal reshaping, corneal refractive therapy or vision shaping.
These lenses work well with children and adults for myopia control. It temporarily reshapes your cornea while you sleep, which will eventually have an impact on the overall shape of the eye and improve the refraction of light into the retina.
This revolutionary procedure helps people minimise their need for glasses or daytime contact lenses. Since Ortho K is a carefully designed therapeutic contact lens that helps reshape your eye while you sleep, you’ll wake up with a clear, sharp, and natural vision.
Orthokeratology, by form of overnight lenses takes a gentle approach to shaping the cornea, making orthok lenses an ideal solution for short sighted children of most ages. Using a gentle solution like orthok lenses, is especially useful for those who are too young to be treated by invasive vision correction procedures like laser surgery.
Besides helping children with short sightedness, the benefits of orthok overnight lenses extends to adults too. Othokeratology can be used as a great temporary solution to short sightedness and help treat anyone with mild to moderate forms of myopia / short sightedness.
One study of orthokeratology on children in Melbourne found that myopia / short sightedness stabilised in 64% of the participating children. Following the insertion of orthok lenses before bedtime, the orthok lenses work to reshape the cornea and then help the eyes absorb maximum light refraction. Over time, this means the orthok lenses will help to create a reduction in myopic loss of sight.
HOW DO ORTHOK CONTACT LENSES WORK?
Orthokeratology begins its work when placing the orthok lenses in to the eyes at night time before going to sleep. Once inserted, the lenses will comfortably sit on the surface of the eye, with minimal discomfort, just like a normal pair of contact lenses.
Overnight, the orthok lenses work very gently to reshape the cornea. The cornea is the area of the eye that focuses light onto the fovea. The fovea is the area of the eye that sends image signals to the brain's occipital lobe. With such reshaping, the occipital lobe starts to receive significantly clearer image signals and has a much easier time interpreting the images it’s helping us to see.
Orthokeratology lenses are designed to provide a temporary yet helpful solution for short sightedness. The effects of wearing ortho-k lenses will last for around 24 hours. During this time, ortho k contacts users do not need to worry about wearing prescription glasses or contacts lenses all day. Such benefits are found especially useful for those who work in certain professions, where prescription glasses are cumbersome and can, at times, play a part in eye strain when used all the time.
WHAT ARE THE BENEFITS OF OVERNIGHT LENSES?
As mentioned, myopia, otherwise referred to as short sightedness or near sightedness, is a common problem in adults as well as children. One of the most popular solutions to myopia for adults in this day of age, is laser surgery. As an effective and safe procedure, it provides satisfying and long-lasting results. However, laser surgery can be an expensive procedure and some patients are hesitant about the use of this surgery through various reasons, predominantly because it is done whilst awake and the eyes can be incredibly sensitive for weeks, sometimes months after.
Orthok overnight contact lenses can act as a great temporary solution for people with myopia. Orthok lenses can allow a user to take a little extra time to try an alternative solution to surgery. It may be a simple case that implementing these overnight lenses changes their quality of life significantly. For this reason, those who are hesitant about eye surgery, orthokeratology allows them to see whether they feel surgery is really a necessary course of action for their myopia / short sightedness.
For those who choose to continue the use of overnight orthok lenses, the corneal reshaping process with orthokeratology may lead to less reliance on prescription glasses and / or lenses during the day. In the long term, this can help to create a significant reduction in outgoing prescription costs.
WHO IS A GOOD CANDIDATE FOR ORTHOKERATOLOGY?
Good candidates for OrthoK are young people with progressive myopia or nearsightedness who are aged 8 to 12. Adolescents and adults will also benefit from ortho k.
Children and young adults, who struggle with wearing glasses or are too young for LASIK and are not allowed to have refractive surgery, are often good candidates for orthokeratology.
Athletes or people who participate in contact sports are also good candidates. The corneal reshaping effect is temporary, which involves minimal risks and discontinuing the use of the lenses anytime is possible. But, you may need to start wearing glasses or contacts again in case your myopia returns.
