We describe 6 surgical techniques used to implant a silicone iris prosthesis: sector-shaped iris segments that require suturing, injector-assisted sulcus fixation, injector-assisted capsular bag fixation with an intraocular lens (IOL) and capsular tension ring, folded iris tissue implanted with a forceps and sutured to the sclera with a scleral-fixated IOL, "sandwich" or "backpack" implantation with an IOL, and open-sky implantation with a perforating keratoplasty. The results of the techniques performed in 51 patients are discussed. Sector-shaped iris segments required longer surgery because of the complexity of intracameral sutures and carried risks for knots to loosen and sutures to cut through residual iris tissue. The combined implantation of an iris and IOL proved complex and lengthy but solved lens and iris abnormalities in 1 procedure and provided long-lasting stable conditions. The procedures that implanted a complete iris in pseudophakic eyes were shorter and required smaller incisions, a sutureless approach, and injector-assisted implantation.
我们描述了 6 种用于植入硅胶虹膜假体的手术技术：需要缝合的扇形虹膜段、注射器辅助巩膜固定、注射器辅助带晶状体（IOL）和囊袋张力环的囊袋固定、用镊子植入折叠的虹膜组织并缝合到巩膜上的巩膜固定 IOL、带有 IOL 的“三明治”或“背包”植入以及伴有穿透性角膜移植术的开放式天空植入。讨论了在 51 名患者中进行的技术的结果。由于房内缝线的复杂性，扇形虹膜段需要更长的手术时间，并且存在结松动和缝线穿过残留虹膜组织的风险。虹膜和 IOL 的联合植入虽然复杂且耗时，但可以在一次手术中解决晶状体和虹膜异常，并提供持久稳定的状态。在无晶状体眼中植入完整虹膜的手术更短，需要更小的切口、无缝线方法和注射器辅助植入。
