Abstract:
Recently, we performed an ezperi nlent to detect residual ethylene oxide(EO) gas and methylmethacrylate(MMA) monomer in the intraocular lenses from eleven different makers using gas-liquid chromatography. The residual EO gas over 25ppm was seen in 2 makers and also the MMA monomer over 2% was present in two makers. As a result, we recommend that the precise product quality-control of the IOLes is necessary especially for the lenses from foreign manufacturers.
