BACKGROUND
A new emerging complication of trans-scleral fixation of posterior chamber (PC) intraocular lens (IOL) with polypropylene suture is high rates of spontaneous dislocation of the IOL due to disintegration or breakage of suture.
MATERIALS
We report a new surgical technique of trans-scleral fixation of posterior chamber intraocular lens (SF PCIOL) with steel suture to eliminate the complication of dislocation of IOL fixed with polypropylene suture in one adult and a child.
RESULTS
We successfully achieved stable fixation and good centration of IOL after SF PCIOL with steel suture in these patient having inadequate posterior capsular support. Both eyes achieved best corrected visual acuity 20/40 at 18 months follow-up.
CONCLUSIONS
Steel suture is a viable option for trans-scleral fixation of posterior chamber intraocular lens.
背景
聚丙烯缝线经巩膜固定后房型人工晶状体（IOL）出现了一种新的并发症，由于缝线的崩解或断裂，导致 IOL 自发性脱位的发生率较高。
材料
我们报告了一种新的经巩膜固定后房型人工晶状体（SF PCIOL）的手术技术，使用钢丝缝线，以消除聚丙烯缝线固定的 IOL 脱位的并发症，该技术在 1 名成人和 1 名儿童中应用。
结果
在这些后囊膜支持不足的患者中，我们成功地通过 SF PCIOL 用钢丝缝线实现了 IOL 的稳定固定和良好的中心定位。在 18 个月的随访中，双眼最佳矫正视力均达到 20/40。
结论
钢丝缝线是经巩膜固定后房型人工晶状体的一种可行选择。
