Supplementary Material for: Repairing Cyclodialysis by Riveting: A Flanged Polypropylene Suture

Cyclodialysis causes intraocular lens (IOL) pupillary capture. It requires surgical repair to prevent this risk of IOL pupillary capture. However, since repairing cyclodialysis is often technically difficult, other methods such as barricading by suturing, pupilloplasty, and pars plana fixation of the IOL were preferred. We applied a double-flanged (riveting) technique for repairing cyclodialysis to prevent IOL pupillary capture following intrascleral fixation of the IOL. Cyclodialysis was surgically repaired by riveting with double-flanged 6-0 polypropylene sutures in 3 cases with no recurrence of pupillary capture during at least 12 months of follow-up. When pupillary capture is related to cyclodialysis, repairing cyclodialysis may help prevent pupillary capture after intrascleral fixation of the IOL. Riveting using a double-flanged 6-0 polypropylene suture could possibly make the procedure simpler and more efficient.

睫状体分离（Cyclodialysis）可引发人工晶状体（intraocular lens, IOL）瞳孔夹持，需通过手术修复以规避此类风险。然而，由于睫状体分离修复术往往技术难度较高，临床常优先选用缝合封堵、瞳孔成形术及人工晶状体睫状平坦部固定术等替代方案。我们采用双瓣（铆合）技术修复睫状体分离，以预防人工晶状体巩膜内固定术后的IOL瞳孔夹持。本研究纳入3例患者，均通过6-0聚丙烯缝线行双瓣铆合术完成睫状体分离修复，且在至少12个月的随访周期内未出现瞳孔夹持复发。若瞳孔夹持与睫状体分离相关，修复睫状体分离有助于预防人工晶状体巩膜内固定术后的瞳孔夹持问题。采用6-0聚丙烯缝线的双瓣铆合技术或可简化手术流程、提升操作效率。
