The introduction of the femtosecond laser to the field of cataract surgery offers many potential benefits. The femtosecond laser is able to perform three important steps in cataract surgery: capsulotomy, lens fragmentation and corneal incisions. Although evidence in support of its efficacy is accumulating, there is a surgical learning curve that needs to be addressed. This review outlines key issues to consider when contemplating the transition to laser cataract surgery in clinical practice.
Laser cataract surgery has been shown to be associated with an initial learning curve. Femtosecond lasers produce a more accurate and precise anterior capsulotomy, improve intraocular lens centration and reduce intraocular lens tilt. Visual and refractive outcomes, although in a limited number of studies, have been shown to be at least as good as those of conventional phacoemulsification. The impact of reduced phacoemulsification energy on the corneal endothelium is still being investigated.
The automation of key steps by the use of femtosecond lasers in cataract surgery has several potential advantages. Emerging literature supports the transition from conventional phacoemulsification to the laser cataract surgery.
飞秒激光在白内障手术领域的引入带来了许多潜在的好处。飞秒激光能够完成白内障手术的三个重要步骤：囊膜切开、晶状体粉碎和角膜切口。尽管支持其疗效的证据正在不断积累，但仍存在需要解决的手术学习曲线问题。本综述概述了在临床实践中考虑向激光白内障手术过渡时需要考虑的关键问题。
激光白内障手术已被证明与初始学习曲线相关。飞秒激光可产生更精确的前囊膜切开术，改善人工晶状体的中心定位并减少人工晶状体倾斜。尽管研究数量有限，但视觉和屈光结果至少与传统的超声乳化白内障吸除术一样好。减少超声乳化能量对角膜内皮的影响仍在研究中。
在白内障手术中使用飞秒激光实现关键步骤的自动化具有许多潜在优势。新出现的文献支持从传统的超声乳化白内障吸除术向激光白内障手术的转变。
