Examination of 273 eye-drops, returned to a hospital pharmacy by out-patients showed that 27% were contaminated. Common contaminants included Bacillus spp, Staphylococcus albus and Sarcina spp. Those eye-drops containing the preservatives chlorbutol or thiomersal showed above average levels of contamination, thus questioning the suitability of these preservatives for ophthalmic preparations.
