白内障(cataract)是发生在眼球里面晶状体上的一种疾病，任何晶状体的浑浊都可称为白内障，但是当晶状体浑浊较轻时，没有明显的影响视力而不被人发现或被忽略而没有列入白内障行列。根据调查，白内障是最常见的致盲和视力残疾的原因，其手术方式经历了巨大的变革，新近发展的飞秒激光技术-一种以超短脉冲形式运转的激光，其具备瞬时功率大，聚焦尺寸小，穿透性强，精密度高的优势。飞秒激光辅助下白内障手术(FSL-assisted cataract)在临床广泛运用。“,”Cataract (cataract) is in the eye of the lens of a disease, any lens turbidity can be said for cataract, but when the lens opacity is light, there is no obvious influence on visual acuity and not be found or is ignored and not included in the ranks of the cataract. According to the survey, cataract is the most common of blindness and visual disability reason, the operation mode, the experienced great changes, recent development of femtosecond laser technology---a ultrashort pulse operation of the laser, it has large instantaneous power and small focus size, strong penetrability, the advantage of high precision. Femtosecond laser assisted white Cataract surgery (FSL-assisted cataract) is widely used in clinic.
