Abstract

Partial or total iris defects (aniridia), either congenital or acquired, may represent a therapeutic and surgical challenge. Not only present these patients with several visual disabilities and concomitant eye diseases (e.g., corneal opacity, cataract, glaucoma), they experience considerable aesthetic impairment. Recently, a new biocompatible foldable and custom-made silicon iris prosthesis was introduced (Customflex® Artificialiris; HumanOptics, Erlangen, Germany), which enabled development of new surgical techniques for the reconstruction of anterior segment in patients with iris defects in aphakic or pseudophakic eyes, whether with intact or compromised capsular support. Currently, several surgical techniques are reported for artificial iris implantation including implantation in the capsular bag or ciliary sulcus, four-floating suture technique, and scleral fixation techniques in combination with IOL implantation. This chapter provides a systematic overview of current surgical approaches for the artificial iris implantation with a thorough step-by-step technique description and case presentation including important surgical, pre- and postoperative considerations, and the reported cosmetic and functional results.
