摘要

<正> Purpose: To investigate the cytotoxicity of soft contact lens multi-purpose care solutions which are now in common use in China.Methods: The cell culture method was used. Cytotoxicity was indicated by significant increases in the number of dead cells relative to controls.Results: Cells were exposed to soft contact lens care solutions for 15 min. They were irregular in shape and variable in size. The intercellular space increased and variable in size.The in-tercelluar space increased and the cells became scrunken. With the time of exposure elongated , damage of cells became more severe.Conclusions: Four kinds of soft contact lens multi-purpose care solutions may have harmful effects on the culture of human corneal epithelial cells. Soaked lenses should be rinsed with saline before being placed in the eyes in order to reduce the potential toxicity of contact lens care solutions. Eye science 1998; 14 :45 - 47.
