To evaluate the impact of anterior capsular polishing on capsule opacification and contraction in eyes undergoing femtosecond laser-assisted cataract surgery (FLACS).
This prospective interventional comparative analysis included patients undergoing FLACS between August 2016 and May 2017. The eyes were subdivided into three groups based on the extent of intraoperative anterior capsular polishing performed: complete 360-degree polishing; inferior 180-degree polishing; and no polishing. Visual acuity, posterior capsular opacification (PCO) score, anterior capsular opacification (ACO) grade, and capsulorhexis diameter were evaluated at 1-week, 6-months, and 1-year postoperative visits.
The study included 99 eyes of 90 patients. No significant differences were observed between the three groups in ACO grade and capsulorhexis contraction at all follow-up visits. There was a statistically significant difference in PCO grade among the groups at 6-month and 1-year follow-up but it was found to be clinically insignificant. One eye in the no polishing group underwent neodymium:yttrium-aluminum-garnet (Nd:YAG) capsulotomy at the 1-year follow-up visit.
A lower incidence of PCO was demonstrated in the 360-degree polishing group, although it was visually insignificant. No significant difference in postoperative capsular contraction was demonstrated between the cohorts up to one-year follow-up.
评估飞秒激光辅助白内障手术（FLACS）中前囊抛光对囊膜混浊和收缩的影响。
本前瞻性干预性对比分析纳入了 2016 年 8 月至 2017 年 5 月期间接受 FLACS 的患者。根据术中前囊抛光的程度将眼部分为三组：完全 360 度抛光；下 180 度抛光；不抛光。在术后 1 周、6 个月和 1 年随访时评估视力、后囊混浊（PCO）评分、前囊混浊（ACO）分级和囊膜切开直径。
该研究纳入了 90 例患者的 99 只眼。在所有随访中，三组间 ACO 分级和囊膜切开收缩均无显著差异。在 6 个月和 1 年随访时，各组间 PCO 分级存在统计学差异，但临床意义不大。1 只眼在不抛光组在 1 年随访时行钕：钇-铝石榴石（Nd：YAG）囊膜切开术。
360 度抛光组 PCO 发生率较低，但视觉上无显著差异。在 1 年随访时，两组间术后囊膜收缩无显著差异。
