To assess the visual outcome and complications in patients after Ab-externo scleral fixation of intraocular lens in pediatric age group (15 years or less).
This quasi experimental study was conducted at Isra Postgraduate Institute of Ophthalmology, Al-Ibrahim Eye Hospital, Karachi, from January 2012 to December 2012. All cases included were worked up according to the protocol. All patients underwent Ab-externo scleral fixation of IOL under general anesthesia. Patients were followed up at 1(st)day, 1(st)week, 1(st)month, 2(nd)month and 3(rd)month. Complete eye examination including best-corrected visual acuity and complications were noted on each visit.
Thirty patients were included in the study, with mean age of 8.6 years (±3.93569). Most of the patients, 20 (66.7%), had visual acuities of 6/18 or better. No complication was seen in 18 (60%) of the patients intra operatively while soft eye was observed in 7 (23.3%) of the patients. Another complication noted was vitreous hemorrhage, which was seen in 5 (16.7%) patients. Most common post-operative complication was Uveitis followed by astigmatism. Lens dislocation and iris abnormalities were seen in only one patient. Most of the patients showed significant visual improvement after surgery.
Ab-externo scleral fixation of an IOL was found to be safe and showed favorable postoperative results with fewer complications.
评估儿童期（15 岁或以下）眼内人工晶状体经巩膜外 ab-externo 固定后的视力结果和并发症。
本准实验研究于 2012 年 1 月至 12 月在卡拉奇的 Al-Ibrahim 眼科医院的 Isra 眼科研究生学院进行。所有纳入的病例均按照方案进行检查。所有患者均在全身麻醉下接受眼内人工晶状体巩膜外 ab-externo 固定术。患者在第 1 天、第 1 周、第 1 个月、第 2 个月和第 3 个月进行随访。每次就诊时均记录全面的眼部检查结果，包括最佳矫正视力和并发症。
本研究共纳入 30 例患者，平均年龄为 8.6 岁（±3.93569）。大多数患者（66.7%，20 例）的视力为 6/18 或更好。18 例（60%）患者术中无并发症，7 例（23.3%）患者出现软眼球。另外还观察到 5 例（16.7%）患者发生玻璃体出血。最常见的术后并发症是虹膜炎，其次是散光。仅 1 例患者出现晶状体脱位和虹膜异常。大多数患者术后视力明显改善。
经巩膜外 ab-externo 固定眼内人工晶状体是安全的，术后结果良好，并发症较少。
