If you or your child is nearsighted (struggles to see things far-off), you'll have heard of orthokeratology.
Also often called OK or ortho-k, orthokeratology has been around because the Sixties. However, it has recently gained interest for its ability to slow the progression of myopia.
Orthokeratology involves wearing specially designed hard contact lenses overnight. Like a mold, the lens temporarily changes the form of the attention whilst you sleep by gently changing the profile of the cornea (the clear, protective outer layer of the attention that acts like a robust lens).
It creates a brief change; When you get up, you're taking off the glasses and make a sound! You can see.
It takes about per week to succeed in full effect but after that – assuming you wear them every night and take them off every morning – you must have the opportunity to go about your days without glasses or contact lenses.
And most significantly, there's good evidence that it will probably help slow the progression of myopia.
However, like all treatments, orthokeratology has its pros and cons – and its risks should be well understood before use.

Occupation
Orthokeratology could also be a pretty option:
-
For individuals who want an alternative choice to glasses but find contact lenses either uncomfortable or unsuitable (because, for instance, they suffer from dry eyework in dusty environments or enjoy water sports)
-
As an alternative choice to refractive surgery, also often called laser eye surgery or LASIK. Refractive surgery is everlasting but orthokeratology is temporary. If you stop using the lenses, things return to normal inside per week.
-
For parents of a toddler who could also be wearing contact lenses in school; ortho-k allows a toddler to attend school without glasses or contact lenses, which will be lost or loosened through the day.
cons
Possible deficiencies include:
-
The upfront cost is higher than every day wear contact lenses where an analogous overall cost is opened up over time
-
The effect wears off if you happen to don't use them every night.
-
All contact lens wear comes with a better risk of eye infection than if you happen to don't wear contact lenses in any respect.
Some people might imagine that orthokeratology carries a better risk of infection than standard soft contact lenses. However, this isn't supported by research evidence.
Oh Study in Japan Compare results after 10 years of wear and tear in children with orthokeratology or soft contact lenses. It found that there have been no serious adversarial events and that the frequency of mild and adversarial events was roughly equal between the groups.
If you get an infection from standard contact lenses or orthokeratology lenses, it often clears up with a course of antibiotics. However, it is feasible to get a rare infection called microbial keratitis, which has the potential to break vision.
This isn't normal. According to at least one the studyIf you wear orthokeratology lenses every night for 1,000 years, you're only prone to get a serious infection.
Orthokeratology lens wearers will dramatically reduce their risk of eye infections if you happen to use sterile contact lens solutions and avoid tap water. Exposure to tap water is just too high for lenses or lens accessories. Increases risk of infection.

Reducing the chance of catastrophic eye disease later in life
It is now estimated. By 2050, half of the world's population will be myopic.and the World Health Organization has sounded the alarm, said one Bulletin:
High myopia greatly increases the chance of macular atrophy, glaucoma and other causes of severe vision loss, the incidence of which isn't reduced by standard contact lens wear.
Slowing the progression of myopia reduces the chance of vision-threatening eye disease. It also means less frequent vision changes, which may get monetary savings in the long term by requiring fewer glasses changes.
Myopia develops. Sharp in younger years, subsequently prevention of myopia control must be advised as early as possible. We don't know exactly how orthokeratology slows the progression of myopia, however it's compelling. research it shows.
If you might be considering orthokeratology to your child, you and your eye specialist have to strike a balance. The child must be sufficiently old to handle it – but wait too long and the myopia control advantages it offers will diminish.
Every child is different. Some are higher able than others to address orthokeratology, or willing to wear it overnight. It will be uncomfortable at first, and a few may find the considered a contact lens overwhelming. It can't be forced.

Review all options.
Orthokeratology isn't the one solution. There are also special lenses you possibly can get for glasses and every day wear soft contact lenses that help slow the progression of myopia. Consult a watch specialist to review all options.
I also advise children to do not more than two hours per day of “close leisure” (meaning non-school work: turning off screen time or reading a book) outside of college hours. Parents may teach childrenThe 20-20 rule(For every 20 minutes of near work, take a 20 second break to have a look at the gap). trip (Two or more hours per day) can also be necessary for healthy eye development in children.
What is obvious, nonetheless, is that each one nearsighted children must do something to regulate their myopia. Just giving a toddler standard single vision glasses isn't enough to assist them see, without doing more to assist slow the progression of myopia.
If right to your child, orthokeratology has a robust research prescription for slowing the progression of myopia.
