方法：回顾性分析。选取2019-06/2020-05行白内障手术患者79例79眼，分为研究组(行飞秒激光辅助超声乳化手术的白内障患者38例38眼)和对照组(行传统超声乳化手术的白内障患者41例41眼)。采用OCT的共焦激光成像技术，收集术前1d，术后1wk，1mo的黄斑小凹厚度和黄斑小凹区、内环区、外环区3个区域平均视网膜厚度，并将术前术后及组间进行比较。

结果：研究组和对照组在术后1wk，1mo时，黄斑小凹厚度、小凹区厚度、外环区厚度较术前均无差异(P>0.05)； 两组手术前后不同时间内环区黄斑厚度有差异(P<0.001)。其中研究组术后1wk内环区黄斑厚度较术前轻度增加，但无差异(P=0.057)，术后1mo较术前和术后1wk均明显增加(均P<0.001)。对照组术后1wk，1mo均较术前明显增加(均P<0.001)，术后1mo较1wk仍轻度增加(P=0.017)。内环区组间比较：术后1wk内环区黄斑厚度对照组明显高于研究组(t=6.233，P<0.05)； 术后1mo内环区黄斑厚度仍略高于研究组(t=7.055，P<0.05)。

结论：飞秒激光辅助白内障手术无明显增加黄斑损害的风险，相较于传统手术方式早期发生黄斑水肿的概率更低，是一种较为安全的手术选择。

METHODS: Retrospective study. From June 2019 to May 2020, 79 eyes of 79 cataract patients were performed cataract surgery in both groups: femtosecond laser-assisted(study group: 38 cases)and conventional phacoemulsification(control group: 41 cases). Fovea and parafoveal macular thickness of cataract patients were measured by Heidelberg OCT preoperatively and 1wk, 1mo postoperatively, and then the difference of measurement results were analyzed.

RESULTS: The retinal thickness of the fovea, the fovea area and the outer retinal ring did not show significant difference in the both groups preoperatively and postoperatively(P>0.05). Retinal thickness in the inner ring in the both groups increased significantly postoperatively, which was statistically significant(P<0.001). In the study group, the macular thickness in the inner ring increased slightly 1wk postoperatively, which was no statistical difference(P=0.057). The inner ring thickness at 1mo increased significantly compared with preoperatively and 1wk postoperatively, and the differences were statistically significant(P<0.001); In the control group, the inner macular ring was significantly thicker at 1wk and 1mo(P<0.001), and the thickness at 1mo was higher than 1wk, which was statistical difference(P=0.017). Comparison between the two groups: the thickness of macular in the inner ring in the control group was significantly higher than the study group 1wk and 1mo postoperatively, which was statistically significant(t=6.233; t=7.055, all P<0.05).

CONCLUSION: Femtosecond laser does not increase the risk of macular damage during operation. Femtosecond laser-assisted cataract surgery is less inflammation and lower macular edema in early, which is a safe surgical option.
