目的：探讨晶状体囊袋不完整患者行改良Yamane法无缝线人工晶状体(IOL)巩膜层间固定术的疗效。

方法：回顾性研究。选取2022年1月至2024年12月于我院治疗的晶状体囊袋不完整患者。根据治疗方案分为改良组采用改良Yamane法无缝线IOL巩膜层间固定术治疗； 传统组采用传统睫状沟缝线悬吊术治疗。术后随访6 mo，比较两组患者手术时间，手术前后最佳矫正视力(BCVA)、视觉质量评分、眼压、IOL位置和并发症。

结果：本研究共纳入患者84例84眼，其中改良组42例42眼，传统组42例42眼，两组患者术前一般资料比较均无差异(均P>0.05)。改良组手术时间(26.97±6.58 min)短于传统组(33.42±7.64 min)(P< 0.01)。术后1、3、6 mo，改良组患者视觉质量评分、BCVA均优于传统组(均P<0.05)。术后6 mo，改良组患者眼压及IOL垂直偏心值均小于传统组(均P<0.05)。随访期间，传统组并发症发生率为19%，改良组并发症发生率为7%，两组患者术后并发症比较无差异(χ²=1.816，P>0.05)。

结论：对于晶状体囊袋不完整患者，采用改良Yamane法无缝线IOL巩膜层间固定术治疗具有较好疗效，可改善视力，缩短手术时间，减少并发症发生，且IOL垂直位置稳定性更好。

METHODS: Retrospective study. Patients with incomplete lens capsular bags who were treated in our hospital from January 2022 to December 2024 were selected. According to the treatment plan, the patients were divided into a modified group, who were treated with the modified Yamane method for sutureless IOL fixation between the sclera layers. The traditional group was treated with the traditional ciliary sulcus suture suspension surgery. Postoperative follow-up was conducted for 6 mo. The operation time, best corrected visual acuity(BCVA), visual quality score, intraocular pressure, IOL position and complications were compared between the two groups of patients.

RESULTS: A total of 84 patients(84 eyes)were included in this study. Among them, 42 patients(42 eyes)were in the modified group, and 42 patients(42 eyes)were in the traditional group. There was no difference in the general preoperative data between the two groups(all P>0.05). The surgical time of the modified group was(26.97±6.58 min), which was shorter than the traditional group's(33.42±7.64 min; P<0.01). At 1, 3, and 6 mo after surgery, the modified group showed better visual quality score and BCVA than the traditional group(all P<0.05). At 6 mo after surgery, the intraocular pressure and the vertical deviation of the IOL in the modified group were both lower than those in the traditional group(all P<0.05). During the follow-up period, the complication rate in the traditional group was 19%, while that in the modified group was 7%. There was no statistically significant difference in postoperative complications between the two groups(χ²=1.816, P>0.05).

CONCLUSION:For patients with incomplete lens capsule, the modified Yamane method of sutureless intrascleral fixation of IOL is effective in treating this condition. It can improve vision, shorten the operation time, reduce the occurrence of complications, and ensure better vertical position stability of the IOL.
