Everything You Need to Know about Orthokeratology
According to the data released by the World Health Organization over 1.3 billion people all around the world are suffering from some sort of vision impairment. Usually, people who are suffering from some sort of vision impairment have to wear prescribed spectacles or contact lenses for a clear vision.
Wearing spectacles of contact lenses will help you to see clearly but it won’t cure your eyesight. Some vision impairment can be cured by eye surgery.
But what if you can cure your eyesight without undergoing an eye surgery?
You must be thinking it is impossible but with orthokeratology it is possible.
What Is Orthokeratology?
Orthokeratology also known as Ortho –k is the science of fitting of specially designed gas permeable contact lenses. The person has to wear these specially designed lenses overnight.
These lenses will shape the cornea of your eye while you are asleep so that once you wake up and remove the lenses next morning you can have a clear vision. Orthokeratology lenses or ortho-k lenses are also known as overnight contact lenses or corneal reshaping contact lenses.
In orthokeratology, the lenses that should be used must be highly breathable and should have been approved by the FDA for overnight wear.
Vision Problems That Can Be Corrected By Orthokeratology
Generally, orthokeratology is used to temporarily cure nearsightedness or myopia. It can correct myopia up to -6.00 D. Moreover, orthokeratology is also used to correct smaller degree of astigmatism, presbyopia, and hyperopia. However, it should be noted that the amount of refractive error that can be cured by orthokeratology depends on the severity of the vision problem.
Who Can Avail The Benefits Of Orthokeratology?
Mostly children and teenagers who don’t want to wear spectacles but too young to undergo laser-assisted in situ keratomileuses (LASIK) or not fit for any sort of eye surgery are the ones who can enjoy the benefit of the most of orthokeratology.
People who are suffering from a smaller degree of myopia with or without minor astigmatism can also avail the benefits of orthokeratology. As the reshaping is done to your cornea is a temporary, very little risk is there.
However, you can stop wearing ortho-k lenses whenever you want, but you have to wear spectacles or usual contact lenses instead of ortho-k lenses. People who play intensive sports or work in such an environment where wearing contact lens is not an option are also the ones who can enjoy the benefits of orthokeratology.
How Long Orthokeratology Takes To Show Its Effects?
The time taken by orthokeratology to start showing its effects depends on a number of factors like the degree of severity of myopia. In some cases, people start to enjoy a clear vision after a couple of days of overnight ortho-k. However, for people who are suffering from a higher degree of myopia with or without minor astigmatism may have to wait for a couple of weeks before it starts showing its effect.
Once, orthokeratology starts showing its effect you will be able to see clearly without wearing any spectacle or contact lenses for one or two days. To get the best result you should wear overnight lenses every night.
What Are The Costs?
Fitting orthokeratology lenses is not an easy task. It is a very complex and time-consuming task as it has to be perfect. You will have to visit the doctor and the optometrist several times before getting the final ortho-k lenses.
The cost of fitting of ortho-k lenses depends on the eye doctor, and the time required and the cost of the lenses. Usually, the cost of fitting of ortho-k lenses varies from $1000 to $2000. The cost may be more or less depending on the degree of myopia.
So, people who are suffering from myopia but do not want to wear spectacles or contact lenses, orthokeratology is the best solution for you.
