Résumé
Since their introduction the spectrum of complications of intraocular lenses (IOLs) has changed. Clouding of the IOL material is increasingly described in the literature as a reason for explantation. This study aimed to give an overview of the various pathologies of IOL material. The currently relevant types of IOL material opacities are summarized as well as their effects on the optical quality. In current IOL models calcification can occur in lenses made of hydrophilic acrylate, while in IOLs made of hydrophobic acrylate "glistenings" can develop. These different material opacifications have varying impacts on optical quality parameters and in general lead to an increased intraocular light scattering. In the case of intolerable IOL material opacification, the only treatment option is its removal and the implantation of a new IOL. HINTERGRUND: Das Spektrum der Komplikationen beim Einsatz von Intraokularlinsen (IOL) ist heute ein anderes als zur Zeit ihrer Einführung. Trübungen im IOL-Material werden vermehrt als Explantationsgrund in der Literatur beschrieben. Diese Arbeit soll einen Überblick über die verschiedenen Formen von IOL-Materialeintrübungen geben. Die heute relevanten Formen von IOL-Materialeintrübungen und deren Auswirkungen auf die optische Abbildungsqualität wurden zusammengestellt. Als Grund für eine Eintrübung steht bei hydrophilen IOL die Kalzifikation im Vordergrund, während bei hydrophoben IOL v. a. über die Entstehung sog. „Glistenings“ berichtet wird. Die meisten Materialeintrübungen beeinflussen verschiedene optische Parameter und führen zu einem erhöhten intraokularen Streulicht. Im Falle einer störenden Materialeintrübung besteht die einzige Therapieoption in einem Austausch der eingetrübten IOL.

BACKGROUND
BACKGROUND
Since their introduction the spectrum of complications of intraocular lenses (IOLs) has changed. Clouding of the IOL material is increasingly described in the literature as a reason for explantation.
OBJECTIVE
OBJECTIVE
This study aimed to give an overview of the various pathologies of IOL material.
MATERIAL AND METHODS
METHODS
The currently relevant types of IOL material opacities are summarized as well as their effects on the optical quality.
RESULTS AND CONCLUSION
CONCLUSIONS
In current IOL models calcification can occur in lenses made of hydrophilic acrylate, while in IOLs made of hydrophobic acrylate "glistenings" can develop. These different material opacifications have varying impacts on optical quality parameters and in general lead to an increased intraocular light scattering. In the case of intolerable IOL material opacification, the only treatment option is its removal and the implantation of a new IOL.

UNASSIGNED
Als Grund für eine Eintrübung steht bei hydrophilen IOL die Kalzifikation im Vordergrund, während bei hydrophoben IOL v. a. über die Entstehung sog. „Glistenings“ berichtet wird. Die meisten Materialeintrübungen beeinflussen verschiedene optische Parameter und führen zu einem erhöhten intraokularen Streulicht. Im Falle einer störenden Materialeintrübung besteht die einzige Therapieoption in einem Austausch der eingetrübten IOL.
