Should your cornea have any kind of irregular shape, it can cause the light that enters your eye to be refracted incorrectly. When this happens, the brain cannot understand the images, leading to blurry vision. This situation is known as a refractive error.
What is Myopia?
Myopia is prevalent in both adults and children and its numbers are rising worldwide. Nearly 11% of the global population has it, and studies predict that by 2050, myopia will affect half of the entire world!
This condition is generally treated with the use of eyeglasses or contact lenses, which correct vision by refracting light properly. It’s worth noting that while these solutions improve your vision, they only work so long as you wear them, and they do not cure the condition itself.
According to FDA trials conducted on both CRT and VST lenses, more than 65% of patients achieved 20/20 visual acuity. An impressive 90% achieved 20/40 vision or better, which is an important achievement since this is the legal requirement for driving without vision correction in most states.
What is Orthokeratology?
Ortho-k refers to rigid gas permeable contact lenses that gently reshape the cornea while you sleep. In the morning, simply take the lenses out and go about your day. Since the Ortho-k lenses have reshaped your cornea during the previous night, many patients experience improved vision the following day. Some even find that they don’t need to wear glasses or contacts, but can see clearly without them.
To ensure the most effective treatment, Ortho-k lenses must be custom-fitted for each patient. Dr. Susan Keene will take measurements of the size and curvature of your cornea and create a tailor-made set of lenses to fit your eye’s unique shape. They fit perfectly over the cornea and allow air to pass through, so they won’t dry out. This keeps the Ortho-k lenses moist and comfortable.
How Effective is Ortho-k?
There are currently 3 brands of FDA-approved Ortho-k lenses. Euclid Emerald, usually prescribed for myopia control, Paragon Vision Sciences, which produces “Corneal Refractive Therapy” (CRT), and Bausch and Lomb, which manufactures “Vision Shaping Treatment” (VST).
Is Ortho-k Better Than Eye Surgery?
Adults with myopia may be candidates for eye surgery to correct the refractive error, but children are a different matter. Eye surgery to correct vision is generally not performed on patients younger than 18. This is because children’s vision is unstable during their younger years as their eyes are still developing. Fortunately, kids can benefit from wearing Ortho-k lenses.
Who is a candidate for ortho-k?
Ortho-k is particularly appealing for people who participate in sports, or who work in dusty, dirty environments that can make contact lens wear difficult.

Ortho-k for Children
When worn consistently, Ortho-k can stop myopia from deteriorating further. This is crucial to maintaining healthy eyes because if left untreated, as children grow older, myopia can eventually lead to more severe eye diseases like glaucoma, early onset cataracts, macular degeneration, or retinal detachment. That’s why the doctor recommends earlier treatment. The sooner we can treat your child’s myopia, the lower the risk of more serious vision problems.
