目的:观察34例前囊撕裂伴后囊缺损白内障患者行后房人工晶体虹膜缝线固定术的临床效果。方法:对25例老年性白内障及9例外伤性白内障患者,术中前囊截囊或环形撕囊≥1处撕裂并后囊>3/4缺损行后房人工晶体虹膜缝线固定术。结果:11例术后视力>0.8,14例0.5～0.8;25例视力>0.5,占73.4%。讨论:人工晶体虹膜缝线固定术治疗前囊撕裂伴后囊缺损,方法简单、安全、有效。 Objective: To observe the clinical effect of posterior chamber artificial IOL suture fixation in 34 cases of anterior capsulorhexis and posterior capsule cataract. Methods: 25 cases of senile cataract and 9 cases of traumatic cataract were treated with intraocular anterior capsulotomy or circumcision ≥1 tear and posterior capsule> 3/4 defect with posterior chamber intraocular lens implantation of iris suture. Results: 11 cases of postoperative visual acuity> 0.8, 14 cases of 0.5 to 0.8; 25 cases of visual acuity> 0.5, accounting for 73.4%. Discussion: IOL suture fixation of anterior capsule tears with posterior capsule defect, the method is simple, safe and effective.
