Surgical correction of traumatic aniridia aims to improve the quality of vision, compartmentalize the anterior and posterior chamber, and re-establish a satisfying cosmetic appearance. Various types of prosthetic iris devices (PIDs) are available, which differ in technical difficulty of implant and design: artificial iris (AI)-intraocular lens prosthesis, endocapsular capsular tension ring-based PID, and customized AI. The choice depends on the preexisting clinical condition after severe ocular trauma and on patient functional and cosmetic expectations. This systematic review of the literature compared anatomical and functional outcomes of various types of PIDs. Of 185 articles found in the literature, 70 fulfilled the eligibility criteria. 5 subgroups of PIDs were Ophtec, artificial iris from Ophtec BV, Morcher GmbH, HumanOptics AG, and other prosthesis. Both glare and aesthetic outcome improved postoperatively; in comparison with other PIDs, intraocular pressure rise was higher in the Morcher group (40%), whereas prosthesis dislocation was higher in the Ophtec group (39%).
外伤性无虹膜的手术矫正旨在提高视力质量，分隔前房和后房，并重建令人满意的外观。有多种类型的人工虹膜装置（PID）可供选择，它们在植入技术难度和设计上有所不同：人工虹膜（AI）-人工晶状体假体、基于囊内囊张力环的PID和定制AI。选择取决于严重眼外伤后的现有临床状况以及患者的功能和美容期望。这项对文献的系统评价比较了各种类型PID的解剖学和功能结果。在文献中找到的185篇文章中，70篇符合纳入标准。PID的5个亚组分别是Ophtec、Ophtec BV的人工虹膜、Morcher GmbH、HumanOptics AG和其他假体。术后眩光和美学效果均有所改善；与其他PID相比，Morcher组眼压升高的比例更高（40%），而Ophtec组假体脱位的比例更高（39%）。
