Cataract surgery is among the most frequently performed surgical procedures worldwide and has a tremendous impact on patients' quality of life. Phacoemulsification (PCS) is accepted as a standard of care; its technique has continuously evolved and already achieved good anatomical, visual, and refractive outcomes. Lasers in ophthalmology are widely used in clinical practice, femtosecond lasers (FSLs) for corneal surgery in particular. It was natural to assess the usefulness of FSL in cataract surgery as this technology was within reach. Indeed, precise and reproducible cuttings provided by FSL platforms could improve standardization of care and limit the risk associated with the human element in surgery and provide a step toward robot-assisted surgery. After docking and planning the procedure, femtosecond lasers are used to perform corneal incisions, capsulorhexis, lens fragmentation, and arcuate incisions in an automated manner. A well-constructed corneal incision is primordial as it offers safety during the procedure, self-seals afterward, and influences the refractive outcome. Capsulorhexis size, centration, and resistance to shearing influence the surgery, intraocular lens (IOL) centration and stability, and posterior capsular opacification formation. Lens fragmentation is where most of the energy is delivered into the eye, and its amount influences endothelial cell damage and potential damage to other ocular structures. The arcuate incisions offer an additional opportunity to influence postoperative astigmatism. Femtosecond laser-assisted cataract surgery (FLACS) has been a topic of research in many studies and clinical trials that attempted to assess its potential benefits and cost-effectiveness over PCS and is the subject of this mini-review.
白内障手术是全球最常开展的外科手术之一,对患者的生活质量有巨大影响。超声乳化白内障吸除术(PCS)被公认为一种标准治疗方法;其技术不断发展,已取得良好的解剖学、视觉和屈光效果。眼科激光在临床实践中广泛应用,尤其是飞秒激光(FSL)用于角膜手术。鉴于这项技术已可实现,评估FSL在白内障手术中的效用是很自然的事。事实上,FSL平台提供的精确且可重复的切割可以提高治疗的标准化程度,降低手术中人为因素相关的风险,并朝着机器人辅助手术迈出一步。在对接并规划手术过程后,飞秒激光用于自动进行角膜切口、连续环形撕囊、晶状体粉碎和弧形切口。精心构建的角膜切口至关重要,因为它在手术过程中提供安全性,术后可自行闭合,并影响屈光效果。连续环形撕囊的大小、中心定位和抗剪切力会影响手术、人工晶状体(IOL)的中心定位和稳定性以及后发性白内障的形成。晶状体粉碎是大部分能量传递到眼内的环节,其能量大小会影响内皮细胞损伤以及对其他眼内结构的潜在损伤。弧形切口为影响术后散光提供了额外机会。飞秒激光辅助白内障手术(FLACS)一直是许多研究和临床试验的研究课题,这些研究和试验试图评估其相对于PCS的潜在益处和成本效益,这也是本综述的主题。
