Abstract

Abstract: : Purpose: To investigate possible sources for the induction of silicone oil emulsification in patients'eyes. Methods: Determination of contaminants on a ready-to-use standard set of vitreoretinal instruments and equipment cleaned and sterilized in an eye clinic using their routine procedure. The determination of detergents was carried out according to a standardized method, which uses ultrapurified water to rinse the devices in question, followed by a measurement of the conductivity. Silicone oil remnants were determined using FT-IR spectroscopy. Results: Ionic components of detergents as well as remnants of silicone oil could be detected on "sterile, clean, ready-to-use" instrumentation. Conclusions: During routine cleaning and sterilization of vitreoretinal instruments and accessories remnants of detergents and silicone oil can persist and trigger emulsification of silicone oil which came into contact with these contaminated devices during instillation of the endotamponade.
