Complications after Prosthetic Iris Implantation in a Case of Traumatic Aniridia

Introduction

It is well documented that partial or complete, inborn or traumatic defects of the iris reduce the quality of vision by complex effects on the intraocular optics. Among these, glare and light sensitivity are the most disturbing symptoms accompanied by deterioration of visual acuity, resulting from the inadequate aperture of the eye as well as of optical and chromatic aberration. Reduced contrast vision, depth perception, stereopsis, and esthetics are further handicaps with potential impact on the quality of life, depending on the individual needs of affected patients.

Reconstruction of the iris by prosthetic devices, although available since the introduction of the black diaphragm IOL by Sundmacher et al. [1] in 1994, is still a challenging and not standardized surgical procedure. Several types of novel implants have become available in the last two decades [2], [3], [4], [5], [6] but systematic analyses of the efficacy and especially of complications are lacking. In this case report a complicated development after implantation of a new flexible artificial silicone iris [4] is described.
