Morphology of the capsule-like portion of the reactive membranes on intraocular lens implants

Abstract

The glass-membrane-like capsules probably are the practically most important part of the separating membranes that typically form on intraocular lens implants in the human eye. With time in the eye, these clear capsules become tougher, more firmly adherent, and less eosinophilic. Their formation occurs early after implantation and is associated with the reactions of intraocular macrophages. Examples of well developed capsules are presented to show that only few cells are needed for their maintenance and that they can be of irregular thickness. Cell life on the film-like capsules is demonstrated using the examples of blood-eating macrophages, epitheliod cells, and melanocytes. Attachment of fibrous structures containing zonular fibers to the haptics is recorded.

Zusammenfassung

Die glasmembran-ähnlichen Kapseln sind wahrscheinlich der wichtigste Teil der trennenden Membranen, die sich typischerweise auf intraokulaeren Linsenprothesen bilden. Im Auge werden diese klaren Kapseln mit der Zeit zäher, fester anhaftend und weniger eosinophil. Ihre Bildung geschieht im Auge bald nach der Implantation und ist mit den Reaktionen der intraokulären Makrophagen verbunden. Beispiele von voll entwickelten Kapseln werden gezeigt, um zu zeigen, daß nur wenige Zellen zu ihrer Instandhaltung notwendig sind und daß sie von sehr unregelmäßiger Dicke sein können. Das Zelleben auf den filmartigen Kapseln wird am Beispiel von blutfressenden Makrophagen, Epithelioidzellen und Melanozyten demonstriert. Das Anhaften von fibrösen Strukturen, die Fasern der Zonula lentis enthalten, an haptische Teile der Linsenprothesen wird beschrieben.
