目的：对比两种不同悬吊缝线固定方式改善人工晶状体植入术中的应用。

方法：回顾性研究。纳入2021-01-01/2023-12-01在我院眼科接受人工晶状体悬吊手术患者60例60眼。根据术中不同缝合技术，将患者分为两组：对照组30眼接受巩膜瓣下缝线固定； 观察组30眼接受Z字型缝线固定。术后随访6 mo，比较两组患者手术时长、视力及视觉质量、眼部结构、临床疗效、术后缝线暴露率、屈光度数及人工晶状体位置偏移情况。

结果：观察组手术时长为50.5±3.1 min，对照组为40.9±2.8 min(P<0.01)。术后6 mo两组患者裸眼视力和最佳矫正视力均较术前改善(均P<0.01)，两组间裸眼视力和最佳矫正视力比较均无差异(均P>0.05)； 术后6 mo观察组视觉质量优于对照组(P<0.05)； 两组患者角膜内皮细胞数量与术前比较均有差异(均P<0.01)，但术后两组间无差异(P>0.05)。术后6 mo，两组患者总有效率比较无差异(P=0.542)，两组患者术后缝线暴露率比较无差异(P>0.05)； 两组患者术后屈光度数及人工晶状体偏移值比较均有差异(均P<0.01)。

结论：两种悬吊缝线固定方式在人工晶状体植入手术中均能取得良好的临床效果，但Z字型缝线固定在视觉质量和眼部结构保护方面表现更佳。

METHODS: Retrospective study. A total of 60 patients(60 eyes)who underwent intraocular lens suspension surgery at ophthalmology department of our hospital between January 1, 2021, and December 1, 2023 were included. Patients were divided into two groups based on the suturing techniques: the control group(n=30)received sub-scleral flap suture fixation, while the intervention group(n=30)underwent Z-shaped suture fixation. A 6 mo postoperative follow-up was conducted to assess surgical duration, visual acuity and quality, ocular structure, clinical efficacy, postoperative expose rate of sutures, diopters and decentration of intraocular lens.

RESULTS:The mean operative time was significantly longer in the intervention group(50.5±3.1 min)compared to the control group(40.9±2.8 min; P<0.01). At 6 mo postoperatively, both groups demonstrated significant improvements in uncorrected and best-corrected visual acuity compared to preoperative values(both P<0.01), and there were no statistically significant differences in the uncorrected and best corrected visual acuity between the two groups(all P>0.05); at 6 mo postoperatively, the visual quality of the intervention group was better than that of the control group(P<0.05). While both groups exhibited a significant reduction in corneal endothelial cell count postoperatively(both P<0.01), there was no significant difference between the groups(P>0.05). The overall efficacy rate and suture exposure rate were comparable between the groups at 6 mo postoperatively(P=0.542 and P>0.05, respectively). However, significant differences were observed in postoperative diopters and intraocular lens decentration between the two groups(both P<0.01).

CONCLUSION:Although both suture fixation techniques yielded satisfactory clinical outcomes in intraocular lens implantation, the Z-shaped suture fixation demonstrated superior performance in terms of visual quality and preservation of ocular structural integrity.
