Let’s begin with “Myopia.” Exactly what is it? Myopia is the medical term for “nearsightedness,” a condition affecting nearly three million Americans a year, where a refraction error of the cornea hinders light to bend properly, making objects far away appear blurry. While this condition is technically chronic, recent advancements in the eye industry have made it possible for people with low Myopia to temporarily correct their vision through a process called Orthokeratology, or “Ortho-k.”
Today, Myopia presents itself at an earlier age in more children than in the past. Studies have shown that part of the increase in nearsightedness is because more people are doing work up close; this isn’t just a computer and increased screen time, though–reading for long periods can also impact your eyes. There are four options your eye doctor may use for myopia control in children.
Unfortunately, not everyone is a candidate for CRT lenses. Only those individuals who have low to moderate nearsightedness (with or without astigmatism) can benefit from CRT treatment at this time. The best candidates for Orthokeratology are children between the ages of eight and 12 who have progressive Myopia. If early stages of nearsightedness are caught soon enough, Ortho-k can sometimes help with restoring vision in children, because the custom lenses “mold” the eyes overnight to hinder or encourage the growth of cells. Ortho-k also works well with adolescents and young adults with mild or moderate Myopia, or for adults under the age of 40 who aren’t interested in LASIK or other eye corrective surgery. If you suffer from Dry Eye Syndrome or have severe Myopia, Ortho-k is not recommended.
