Background To report the indications, visual outcomes, and intra-operative and post-operative complications of iris-sutured posterior chamber intraocular lens (IOL) in eyes with inadequate capsular support and complex ocular history. Methods A chart review and data analysis of eyes that underwent iris fixation of posterior chamber (PC) IOL for correction of aphakia, dislocated and subluxed IOLs, ectopia lentis, and IOL exchange. Data included clinical risk factors, associated eye conditions, previous surgeries, and concomitant procedures. The pre-operative and post-operative vision, manifest refraction, endothelial cell density, intraocular pressure (IOP), as well as intra-operative and post-operative complications were also recorded. Results One hundred and seventeen eyes from 114 patients were examined with a mean follow-up of 22.4 months. The most common identifiable predisposing risk factor was high myopia in 23 eyes. A significant improvement in uncorrected and best corrected visual acuity compared with baseline was observed. The most common post-operative complications included recurrent IOL subluxation in 16 (13.7%) eyes, IOP spike in 7 (5.9%) eyes, cystoid macular oedema in 5 (4.3%) eyes, and epiretinal membrane formation in 4 (3.4%) eyes. There was one (0.85%) case of sterile endophthalmitis. Conclusions Iris suture fixation of PC IOLs is a good treatment option for eyes with inadequate capsular support and complex ocular history.

虹膜固定人工晶状体在囊膜支撑不足和眼科病史复杂的情况下的结果和并发症
背景 报告虹膜缝合后房型人工晶状体 (IOL) 在囊膜支撑不足和眼病史复杂的眼睛中的适应症、视力结果以及术中和术后并发症。方法 对接受后房 (PC) IOL 虹膜固定术矫正无晶状体、IOL 脱位和半脱位、晶状体异位和 IOL 置换的眼睛进行图表审查和数据分析。数据包括临床危险因素、相关眼部状况、既往手术和伴随手术。还记录术前和术后视力、明显屈光、内皮细胞密度、眼压（IOP）以及术中和术后并发症。结果 对 114 名患者的 117 只眼睛进行了检查，平均随访时间为 22.4 个月。最常见的可识别诱发危险因素是 23 只眼睛的高度近视。与基线相比，观察到未矫正视力和最佳矫正视力的显着改善。最常见的术后并发症包括 16 只眼（13.7%）复发性 IOL 半脱位、7 只眼（5.9%）眼压升高、5 只眼（4.3%）眼出现黄斑囊样水肿以及 4 只眼（3.4%）眼视网膜前膜形成眼睛。无菌性眼内炎1例（0.85%）。结论 对于囊膜支撑不足和眼科病史复杂的眼睛，虹膜缝合固定 PC IOL 是一种良好的治疗选择。
