The purpose of this study was to compare the short-term changes in retina and choroidal tissue after femtosecond laser-assisted cataract surgery (FLACS) and standard phacoemulsification (PE) surgery.
In all, 25 eyes undergoing FLACS and 27 eyes undergoing PE surgery were included in this nonrandomized, retrospective, cross-sectional study. Central retinal thickness (CRT) and choroidal thickness (CT) were measured pre- and postoperatively (at day 1, 1 week later, and after 1 month) with spectral domain optical coherence tomography (OCT) in all patients and were compared. For group comparisons, chi-square test and independent -test were used. Postoperative values were compared to the baseline using a paired -test. The magnitude of the change from baseline to the peak was analyzed by multiple regression models in an attempt to explain possible influence variables.
Pre and postoperative CRT measurements were similar in both groups. The mean subfoveal CT at day 1, after 1 week, and 1 month were significantly higher than baseline CT measurements in the PE group.
FLACS might have an advantage in regard to postoperative choroidal changes.
本研究旨在比较飞秒激光辅助白内障手术（FLACS）和标准超声乳化白内障吸除术（PE）术后视网膜和脉络膜组织的短期变化。
本非随机、回顾性横断面研究纳入了25例行FLACS手术的眼和27例行PE手术的眼。所有患者均在术前及术后（第1天、1周后和1个月后）使用光谱域光学相干断层扫描（OCT）测量中心视网膜厚度（CRT）和脉络膜厚度（CT），并进行比较。组间比较采用卡方检验和独立样本t检验。术后值与基线值采用配对t检验进行比较。通过多元回归模型分析从基线到峰值的变化幅度，以试图解释可能的影响变量。
两组术前和术后CRT测量值相似。PE组术后第1天、1周后和1个月时的平均黄斑下CT显著高于基线CT测量值。
FLACS在术后脉络膜变化方面可能具有优势。
