The purpose of the study was to review the safety and stability of scleral-fixated intraocular lens (IOL) 2 years after implantation in children with idiopathic ectopia lentis (EL).
This retrospective case series enrolled children with EL managed between 2011 and 2015 at a tertiary eye hospital in the eastern of Saudi Arabia. Data were collected on age, gender, vision, isolated or syndromic pathology, intraoperative and postoperative complications, spherical equivalent refraction, and final best-corrected visual acuity (BCVA).
The series included 18 eyes of 11 children with EL (6 males and 5 females). There were 7 bilateral and 4 unilateral cases. The median age was 3.5 years (25% quartile 1 year; range: 1-8 years). Preoperatively, fixation was absent in 3 eyes, 8 eyes were fixating but vision could not be recorded. In the remaining seven eyes, median distant visual acuity was 0.1 (25% quartile: 0.08). The median postoperative follow-up was 24 months (25% quartile, 7 months). Complications included two eyes with iris capture and one eye with lens subluxation requiring re-implantation. Postoperative BCVA was better than 20/60 in 15 (83%) eyes. At last follow-up, 6 eyes required myopic correction, 1 eye was emmetropic, and 11 eyes were hypermetropic. One eye with glaucoma was managed medically.
Scleral fixated IOL in eyes of young children with EL had good visual outcomes and high stability. However, there is a high incidence of residual refractive error.
本研究旨在回顾特发性晶状体异位（EL）患儿植入巩膜固定人工晶状体（IOL）2年后的安全性和稳定性。
本回顾性病例系列纳入了2011年至2015年在沙特阿拉伯东部一家三级眼科医院接受治疗的EL患儿。收集了年龄、性别、视力、孤立性或综合征性病理、术中及术后并发症、等效球镜度屈光不正以及最终最佳矫正视力（BCVA）等数据。
该系列包括11例EL患儿的18只眼（6例男性和5例女性）。有7例双侧病例和4例单侧病例。中位年龄为3.5岁（四分位数间距1年；范围：1 - 8岁）。术前，3只眼无固视，8只眼有固视但无法记录视力。在其余7只眼中，中位远距离视力为0.1（四分位数间距：0.08）。术后中位随访时间为24个月（四分位数间距，7个月）。并发症包括2只眼发生虹膜夹持和1只眼晶状体半脱位需要再次植入。15只眼（83%）术后BCVA优于20/60。在最后一次随访时，6只眼需要近视矫正，1只眼光学矫正，11只眼为远视。1只青光眼眼接受药物治疗。
EL幼儿眼中植入巩膜固定IOL具有良好的视觉效果和高稳定性。然而，残余屈光不正的发生率较高。
