Myopia is increasingly affecting young people in Taiwan, with close to 90 percent of children in Taiwan’s major cities suffering from nearsightedness. If myopia is not controlled and a child’s vision worsens, their eyesight could be damaged, even with treatment. In these cases, it could cause complications such as degeneration, detachment or tearing of the retina, macular degeneration, cataracts and glaucoma. In serious cases surgery may be required, and the complications could even lead to impaired vision.
Main preventative treatments for myopia are the application of Atropine drops or wearing corneal reshaping lenses. The more concentrated the Atropine drops are, the more effective they are at controlling the myopia, but the stronger the side effects, including photophobia, blurred vision, will be and, if used incorrectly, they could even drastically exacerbate the myopia.
Corneal reshaping lenses are contact lenses to be worn overnight, and must be worn for at least eight hours while sleeping. The biggest problem and greatest risk with these contacts, just as with conventional contact lenses, is infection. If they are not cleaned properly they could breed pathogenic bacteria, leading to corneal infection.
