Abstract

Contact lens related disease is a potentially blinding disease. Although the absolute risk is low, this grave complication could be prevented by proper contact lens handling system. The purpose of this study to identify, isolate and confirm the presence of pathogenic microorganism in contact lens storage cases. The presence of pathogenic microorganisms due to non-compliance of hygienic practices among the subjects was also studied. Microbiological techniques were used to identify samples from asymptomatic contact lens wearers. Ten contact lens storage cases samples were culture positive. Five different Gram negative and one Gram positive organisms (Enterobacter spp., Klebsiella spp., E.coli, Aeromonas spp., Providencia spp. and S. aureus) were isolated from the samples. They were considered as potentially pathogenic organisms after biochemical tests as a confirmation method was done. Through questionnaire assessment, the findings showed the subjects did not truly follow the hygienic practice in lens care system. New and more sensitive methods such as Polymerase Chain Reaction (PCR) should be applied in future to detect other than bacteria which may be a potential contaminant in contact lens storage cases.
