Intraocular lens (IOL) implantation in pediatric eyes with insufficient capsular support is challenging and there are multiple IOL options. These include placement of an IOL within the capsular bag with a capsular tension ring, a scleral-fixated posterior-chamber IOL (PCIOL) with or without capsular tension segment or ring, an intra-scleral fixated IOL, an iris-sutured PCIOL, or an anterior chamber iris-fixated IOL. We reviewed 48 articles and 1 published abstract describing the surgical techniques, complications and visual outcomes of different IOL options in the management of aphakic pediatric eyes with insufficient capsular support. The present review found that the visual acuity outcomes of various IOLs are comparable. Furthermore, each IOL design and surgical technique has different rates of serious complications, including IOL dislocation or decentration, intraocular hemorrhage, glaucoma, endothelial cell loss, and endophthalmitis. An understanding of the risks and benefits of different IOL designs is important for counseling patients and families.
在囊膜支持不足的小儿眼内植入人工晶状体(IOL)具有挑战性,并且有多种IOL可供选择。这些选择包括在囊袋内放置带有囊袋张力环的IOL、带有或不带有囊袋张力节段或环的巩膜固定后房型IOL(PCIOL)、巩膜内固定IOL、虹膜缝合PCIOL或前房虹膜固定IOL。我们回顾了48篇文章和1篇已发表的摘要,这些文献描述了在处理囊膜支持不足的无晶状体小儿眼时不同IOL选择的手术技术、并发症和视觉效果。本综述发现,各种IOL的视力结果相当。此外,每种IOL设计和手术技术的严重并发症发生率不同,包括IOL脱位或偏心、眼内出血、青光眼、内皮细胞丢失和眼内炎。了解不同IOL设计的风险和益处对于向患者及其家属提供咨询很重要。
