Nearsightedness may be corrected with glasses, contact lenses or refractive surgery. Depending on your vision problem, you may need to wear your glasses or contact lenses all the time, or only when you need distance vision, like driving, seeing a chalkboard or watching a movie. With myopia, your prescription is a negative number. The higher the numeral, the stronger your lenses will be. Refractive surgery can reduce or even eliminate your need for glasses or contacts. The most common procedures are performed with an excimer laser. In photorefractive keratectomy, or PRK, the laser removes a layer of corneal tissue, which flattens the cornea and allows light rays to focus closer to or even on the retina. In laser-assisted in situ keratomileusis (LASIK) ? the most common refractive procedure ? a flap is cut through the top of the cornea, a laser removes some corneal tissue, and then the flap is dropped back into place. Also, at Magrabi we provide the latest techniques to treat Myopia like LASEK and EPILASIK. You check our Vision Correction Corner and review the different options.
