To assess the outcomes of iris fixated (IF) posterior chamber (PC) intraocular lens (IOL) versus scleral-fixated (SF) PC IOL implantation, and compare them with the results reviewed from the literature.
The study took place in the ophthalmology department of the Eye and Ear Hospital (Lebanon).
This is a retrospective institutional study that collected the records of patients admitted for secondary IOL implantation between January 2007 and December 2016.
A total of 28 eyes that underwent PC IOL fixation were included, 13 of which underwent trans-scleral PC IOL fixation and 15 of which underwent iris PC IOL fixation. Data were analyzed over a period of 3 years.
Of the 28 patients, 18 (64.3%) were male and 10 (35.7%) were female (mean age at intervention 36.78±23.47 [standard deviation, SD] years). There were no significant intergroup differences with regard to baseline values and demographic characteristics. Trauma was the most common etiology for posterior capsule insufficiency (82.1%). The mean preoperative baseline BCVA was 0.58±0.27 logMAR for SF and 0.27±0.20 logMAR for IF (P=0.07). Both groups had significant improvement in vision during the follow up period. No significant differences were noted regarding early or late postoperative complications between the two groups.
SF and IF techniques for PC IOL have similar outcomes and result in a significant improvement in BCVA. When compared to AC (anterior chamber) IOL, both techniques seem to yield fewer complications.
评估虹膜固定（IF）后房型（PC）人工晶状体（IOL）植入与巩膜固定（SF）PC IOL植入的效果，并与文献综述结果进行比较。
该研究在眼耳医院（黎巴嫩）眼科进行。
这是一项回顾性机构研究，收集了2007年1月至2016年12月期间因二期IOL植入入院患者的记录。
共纳入28只接受PC IOL固定的眼，其中13只接受经巩膜PC IOL固定，15只接受虹膜PC IOL固定。对3年期间的数据进行分析。
28例患者中，18例（64.3%）为男性，10例（35.7%）为女性（干预时平均年龄36.78±23.47[标准差，SD]岁）。两组在基线值和人口统计学特征方面无显著差异。外伤是后囊膜不全最常见的病因（82.1%）。SF组术前平均基线最佳矫正视力（BCVA）为0.58±0.27 logMAR，IF组为0.27±0.20 logMAR（P = 0.07）。两组在随访期间视力均有显著改善。两组术后早期或晚期并发症无显著差异。
PC IOL的SF和IF技术效果相似，可显著改善BCVA。与前房型（AC）IOL相比，这两种技术似乎并发症更少。
