The microbial contamination in contact lens care systems and conjunctivas of 40 asymptomatic cosmetic soft contact lens wearers was investigated. Patient ages ranged from 19 to 27(mean:22), most of them have used hydrogel contact lenses for less than 1 year, and the ages of lens cases were 1 weeks ∼ 3 months (43 %) or 4∼6 months (52%). Twenty-seven patients (67%) chemically disinfected their lenses and 8(20 %) used hydrogen peroxide, and 5 used heat to disinfect. Fourteen patients used commercial non-preserved saline, and 26(65%) were using commercial preserved saline. Sixty-two percent of the patients had bacterial contamination of lens case, and 17% had conjunctival contamination. The bacterial contamination rate was highest in lens cases, followed by unpreserved salines, disinfecting chemicals(non-hydrogen peroxide), and conjunctivas. The fungal contamination rate of cases and conjunctivas was 67% and 15%, respectively, and lens case, unpreserved saline, and conjunctiva seemed more susceptible to contamination. The use of hydrogen peroxide for disinfection rather than chemical disinfection was associated remarkabley with decreased contamination of solution itself, and there was no significant difference in contamination rates between hydrogen peroxide care system and other disinfecting systems. Five of lens cases(13%) and 2 conjunctivas(5%) were contaminated with Pseudomonas aeruginosa, and Candida albicans were isolated from 11cases (27%) and 5 conjunctivas (12%). Of the organisms that were contaminated lens cases and conjunctivas, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Aspergillus fumigatus were isolated from lens cases, whereas Pseudomonas aeruginosa, Candida albicans, and Aspergillus fumigatus were recorvered from conjunctivas. Fortunately all of the these tested samples showed 0% of Acanthamoeba in this investigation.
