Membrane formation and endothelial cell growth on an intra-ocular lens in the human eye, a SEM study

Abstract

In this study we have demonstrated the formation of an acellular and a cellular membrane on the surface of an explanted intra-ocular lens by scanning electron microscopy. The acellular membrane is considered to be the result of a physiological process, whereas the cellular membrane is looked upon as a pathological endothelial membrane formed as the result of intermittent touch between the implant and the endothelium.

Physical and cytological characters of carbon, titanium surface modified intraocular lens in rabbit eyes

“…When an IOL is inserted in the eye, biological interactions occur; these include protein deposition [8,17], complement activation [14,24], and cellular adhesion [15,26]. In order to improve PMMA-IOL biocompatibility and reduce implantation complications, we performed carbon (C) and titanium (T) surface modification on PMMA-IOLs using the technique of carrier energy ion beam combined low temperature and low-pressure plasma.…”
