Is Orthokeratology a subject you’re familiar with? If you don’t know anything about this topic, you don’t need to worry. If you keep reading, you’ll be able to learn more about this vision correction method.
What Is Orthokeratology?
Orthokeratology is a long and intimidating word, but it’s used to describe something that is easy to understand. Orthokeratology — also known as ortho-k — describes the process of fitting people with contact lenses that are gas permeable. These kinds of lenses are used for this overnight vision correction procedure.
The lenses will reshape the front surface of your cornea while you sleep at night. When you wake up in the morning and open your eyes, you’ll be able to see perfectly. These lenses are frequently described as corneal reshaping contact lenses or overnight vision correction contact lenses. They are the only lenses that can safely be worn overnight.
These Lenses Can Correct Many Vision Problems
Not everyone that wears contact lenses wears them for the same reasons. Thankfully, ortho-k lenses can be worn by many people. These lenses can correct several different vision problems.
What kinds of issues can they correct? The lenses can treat astigmatism, myopia, presbyopia, and hyperopia. With that stated, not everyone that suffers from these conditions will be able to wear these lenses. If you want to know whether or not you are a candidate for these lenses, you should schedule an appointment with your eye doctor.
Who Is A Good Candidate For Ortho-K Lenses?
If you suffer from mild astigmatism or myopia, you are likely an excellent candidate for these lenses. People with moderate myopia can also use these lenses without any issues.
These lenses are an ideal choice for people that suffer from dry eyes; they can help to keep the eyes moist. The lenses are also a good option for people that work in dusty environments. They don’t cause the same problems that other lenses do.
If you have more severe issues, however, you may not be eligible to use these lenses. These lenses aren’t able to correct the vision of people with severe myopia. Most eye doctors won’t recommend that people under the age of 13 use these lenses; like most contact lenses, they require extra care.
Where Can I Go To Have Lenses Fitted?
If you are interested in wearing ortho-k lenses, and you believe that you are a candidate for them, you should schedule an appointment with an optometrist or an ophthalmologist. If supervised, a contact lens technician should also be able to handle your fitting.
With that said, you shouldn’t go to just anyone to get your lenses. The process of fitting overnight lenses can be quite difficult. You need to go to someone that has a lot of experience with ortho-k lenses.
What Is The Measuring Process Like?
If you’ve worn contacts in the past, you may feel like you know what to expect. It’s important to remember that the measuring process for ortho-k lenses is different from the process for standard lenses.
Because the lens is going to be fitting itself to your cornea, your doctor will need to measure the natural curves of your cornea. They will be able to do that using a tool called a corneal topographer. Thankfully, this process doesn’t take very long; it should be completed in around a minute.
Depending on your measurements, your doctor may have to have ortho-k lenses custom made for you. If your lenses aren’t ready for a while, you will be given a pair of temporary lenses that you can wear while you wait.
What Kind Of Vision Correction Do These Lenses Provide?
More often than not, you will be able to get perfect 20/20 vision from the lenses that you wear. As long as you have these lenses in, you’ll feel like you don’t have any vision problems at all. These lenses provide excellent vision correction. As long as you are a candidate for the lenses, they should be able to give you perfect vision.
Are These Lenses Comfortable?
If you’re going to have something in your eye all day, you’re not going to want it to cause you discomfort. Ideally, you should be able to forget that the item is even there.
Since ortho-k lenses are designed to be worn overnight, they are incredibly comfortable. A lot of people are pleasantly surprised when they put their lenses in. Once the lenses are in place, it’s hard to feel them at all.
Orthokeratology has created incredible lenses that are comfortable to wear. If you like wearing contacts, but don’t like putting them in and out every night, these kinds of lens should be ideally for you. They have all of the strengths of ordinary lenses but manage to sidestep all of the common drawbacks.
