屈光手術治療以矯正近視眼，已被公認為最有效治療低中度近視眼的方法，但只能解決人們戴眼鏡或隱形眼鏡所造成日常生活中的許多不便，但完全不能預防或治療高度近視所致視網膜的病變，因此預防近視及度數加深才是近視眼防治的目標。此項手術可分準分子雷射屈光角膜塑形術與準分子雷射屈光原位層狀角膜塑形術。對於近視眼的治療效果各有其優點，筆者閱讀相關文獻，探討上述治療方式的益處、合併症，或取代的治療方法等正確觀念，以期在病人考慮接受雷射治療時護理人員能提供適當的協助。

Laser vision correction (LVC), which is adopted to treat myopia, has been recognized as the most effective procedure to treat low to moderate myopia. However, it can only resolve people's inconvenience of wearing glasses or contact lenses. It cannot prevent or cure the pathologic changes of retina which come from the high myopia at all. Therefore, preventing myopia and the increasing of the myopia degree are the most important goals of the myopia preventing. This kind of operation includes photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK). Each has it's own benefits in the result of treatment. After reading several related references, the author started to generalize some LVC conceptions, such as the risk, benefits, and results, even the substitution of above treatments in order to offer appropriate assistance to patients being in consideration of receiving the LVC.
