How CRT Works
Why try to control myopia?
The average rate of myopia progression in a child is 0.50 diopters per year. Some children progress at a much faster rate of 1.00 diopters or more each year. Once a myopia prescription reaches 6.00 diopters, that person is at a significantly higher risk of developing sight-threatening eye conditions such as cataracts, glaucoma and retinal detachments. We want to limit the chance of a child being at a higher risk for these conditions in adulthood. There is also the cost-burden associated with higher prescriptions. Once a myopia prescription reaches certain levels, specialty lens materials are necessary to provide comfortable vision in glasses. And some people need specialty contact lenses as well for their higher prescriptions. Finally, we want to slow down the progression of myopia to improve overall quality of life.
What are treatments to control myopia?
Thankfully there is research that has demonstrated that myopia control treatment programs are effective. On average, the studies have shown about a 50% reduction in myopia progression. There are several different treatment options including atropine drop therapy, multi-focal soft contact lens therapy and orthokeratology (or corneal reshaping therapy). Although all of these methods are approved by the FDA, none are approved by the FDA specifically for myopia control and are therefore utilized as “off-label” techniques.
