目的探讨折叠式人工晶状体(IOL)二期植入术矫正儿童无晶状体眼的疗效和手术适应症。方法对57例(71只眼)后囊膜和悬韧带完整或仅中央区后囊膜缺损的儿童无晶状体眼,二期植入丙烯酸酯(Acrysof)折叠式IOL,术后随访3~25个月。结果术后裸眼视力均等于或高于术前矫正视力,其中术后裸眼视力≥0.5有38只眼(53.5%),术后矫正视力≥0.5有60只眼(84.5%)。并发症包括虹膜后粘连16只眼(22.5%),前房渗出物11只眼(15.5%),IOL偏位6只眼(8.45%),后发障9只眼(12.7%)。结论对于尚存完整或部分后囊膜支撑的儿童无晶状体眼,折叠式IOL植入是一种安全、有效的方法。
Objective To investigate the efficacy and surgical indications of secondary IOL implantation in children with aphakia. Methods Aphakic eyes of 57 children (71 eyes) posterior capsule and suspensory ligament with intact or only posterior capsular defect were implanted with Acrysof foldable IOL in two groups. The patients were followed up for 3 to 25 months month. Results The postoperative uncorrected visual acuity was equal to or higher than the preoperative corrected visual acuity. Among them, the uncorrected visual acuity ≥0.5 in 38 eyes (53.5%) and the corrected visual acuity ≥0.5 in 60 eyes (84.5%). Complications included posterior iridial adhesion in 16 eyes (22.5%), anterior chamber exudate in 11 eyes (15.5%), IOL deviation in 6 eyes (8.45%) and posterior obstacle in 9 eyes (12.7%). Conclusion Foldable IOL implantation is a safe and effective method for aphakic children with intact or partial posterior capsular support.
