Abstract：
BACKGROUND: To investigate the influence of femtosecond laser-assisted cataract surgery (FLACS) on macula by examining changes in retinal layers after FLACS and to compare these changes with those after conventional cataract surgery (CCS).
METHODS: This study included 113 unrelated Korean patients with age-related cataract who underwent CCS or FLACS in Severance Hospital between September 2019 and July 2021. Optical coherence tomography was performed before and 1 month after surgery. The total retinal layer (TRL) was separated into the inner retinal layer (IRL) and outer retinal layer (ORL); moreover, the IRL was subdivided into the retinal nerve fiber layer, ganglion cell layer, inner plexiform layer, inner nuclear layer (INL), outer plexiform layer, and outer nuclear layer. We performed between-group comparisons of the postoperative thickness in each retinal layer and the postoperative differences in retinal thickness. The average retinal thickness of the four inner macular ring quadrants was used for comparative analysis.
RESULTS: Compared with the CCS group, the FLACS group exhibited a thicker ORL (P = 0.004) and a thinner INL (P = 0.007) after surgery. All retinal layer thickness values showed significant postoperative changes regardless of the type of surgery (P < 0.05). The postoperative increase in TRL and IRL thickness was significantly smaller in the FLACS group than in the CCS group (P = 0.027, P = 0.012).
CONCLUSIONS: The 1-month postoperative retinal changes were less pronounced in the FLACS group than in the CCS group.

摘要：
背景：通过检查FLACS后视网膜层的变化，研究飞秒激光辅助白内障手术（FLACS）对黄斑的影响，并将这些变化与常规白内障手术（CCS）后的变化进行比较。
方法：本研究纳入了在2019年9月至2021年7月期间在Severance医院接受CCS或FLACS治疗的113例年龄相关性白内障无关韩国患者。术前和术后1个月进行光学相干断层扫描。全视网膜层(TRL)分为视网膜内层(IRL)和视网膜外层(ORL);IRL被细分为视网膜神经纤维层，神经节细胞层，内丛状层，内核层(INL),外丛状层，和外核层。我们对每个视网膜层的术后厚度和视网膜厚度的术后差异进行了组间比较。使用四个内黄斑环象限的平均视网膜厚度进行比较分析。
结果：与CCS组相比，FLACS组术后ORL增厚(P=0.004),INL变薄(P=0.007).无论手术类型如何，所有视网膜层厚度值均显示出明显的术后变化（P<0.05）。FLACS组术后TRL和IRL厚度增加明显小于CCS组(P=0.027,P=0.012)。
结论：FLACS组术后1个月的视网膜变化比CCS组少。
