目的：探讨虹膜拉钩联合张力环缝合在超声乳化治疗晶状体半脱位继发青光眼中的应用效果。

方法：回顾性病例研究，将2017-10/2020-05长春爱尔眼科医院收治的晶状体半脱位继发急性青光眼患者18眼作为观察组，所有患者在虹膜拉钩辅助下行白内障超声乳化吸除联合人工晶状体(IOL)植入术，术中用虹膜拉钩固定囊袋，植入囊袋张力环(CTR)并固定于脱位侧巩膜。将2015-10/2017-10行白内障囊内摘除联合IOL悬吊术11眼作为对照组。术后观察视力、眼压、晶状体囊袋和IOL位置，记录并发症。

结果：术后至少随访12(12～40)mo，观察组及对照组患者眼压均恢复正常，与术前相比有差异(t=9.994、8.790，均P<0.001)。术后12mo观察组及对照组视力较术前明显提高(Z=-3.900，P<0.001； Z=-3.002，P=0.003)。观察组18眼IOL位置均居中，无IOL夹持、脱位等并发症发生。对照组11眼IOL位置8眼居中，3眼轻度偏位，2眼出现黄斑囊样水肿。

结论：虹膜拉钩联合囊袋张力环缝合植入可作为晶状体半脱位继发青光眼施行原位超声乳化白内障吸出折叠IOL植入术的有效辅助手段，有效控制眼压，并能维持术后囊袋长期稳定性。

METHODS: Retrospective case series. A total of 18 eyes of patients with serious secondary glaucoma associated with lens subluxation were enrolled in Aier Eye Hospital(Changchun)from October 2017 to May 2020 as the observation group. All the patients had iris hooks inserted to support the capsule during the phacoemulsification combined with intraocular lens(IOL)implantation. Iris hooks were inserted through the incisions and placed in the capsulorhexis to support the capsule, then CTR was implanted and sutured onto the sclera of the dislocation side. A total of 11 eyes of patients had intracapsular cataract extraction combined with IOL suspension were enrolled in Aier Eye Hospital(Changchun)from October 2015 to October 2017 as the control group. The postoperative complications were recorded. The postoperative examinations included visual acuity, intraocular pressure(IOP)and positions of the capsule and IOL.

RESULTS: The postoperative follow-up at least 12(12-40)mo, both the IOP of observation group and control group returned to normal, with statistically significant difference compared with pre-operation(t=9.994, 8.790, all P<0.001). At 12mo after operation, the best corrected visual acuity of the two groups were significantly improved compared with surgery before(Z=-3.900, P<0.001; Z=-3.002, P=0.003). The IOL in the observation group of the 18 eyes were in the expected position without complications such as an obvious tilt or displacement. In the control group with 11 eyes, the position of IOL in 8 eyes were centered, 3 eyes were slightly biased, and 2 eyes with cystoids macular edema.

CONCLUSION: The application of suture fixation capsular tension ring and iris hooks for secondary glaucoma associated with lens subluxation in patients can be used as an effective auxiliary method, it could effectively control the IOP and maintain long-term stability of the capsule.
