Femtosecond laser-assisted cataract surgery (FLACS) was introduced with the hope of making cataract surgery safer and making the refractive result more predictable. It is only in the last four years that level 1 prospective randomised controlled trials (RCT) using current technology have been published. These, along with a meta-analysis of recent studies have shown that there seems to be little long-term visual benefit when using FLACS with monofocal lenses. The promised decrease in ultrasound energy required to remove a cataract has not been consistently demonstrated. There is level one evidence that the rate of posterior capsular rupture is less with FLACS using modern software. The round capsulotomy may be of increasing importance with the uptake of toric, multifocal and extended depth of focus lenses where a predictable capsulotomy size and precise placement of the lens becomes more important.
飞秒激光辅助白内障手术（FLACS）的出现是为了让白内障手术更安全，使屈光结果更可预测。直到最近四年，才发表了使用当前技术的一级前瞻性随机对照试验（RCT）。这些研究以及近期研究的荟萃分析表明，使用单焦点晶状体的飞秒激光辅助白内障手术似乎没有长期视觉益处。承诺的降低白内障摘除所需超声能量的效果尚未得到一致证实。有一级证据表明，使用现代软件的飞秒激光辅助白内障手术中后囊破裂率较低。随着散光、多焦点和扩展焦深晶状体的应用增加，圆形撕囊可能变得越来越重要，因为可预测的撕囊大小和晶状体的精确放置变得更加重要。
