Parasitological and microbiological assessment of contact lens storage cases: a survey of asymptomatic lens student wearers from five medical specialties in Tunisia, North Africa.

Background: Contamination of contact lenses has always been correlated with contamination of lenses and lens storage cases (LSCs), with higher loads of microorganisms in LSCs. The aim of the present study is to better understand non-compliance with strict hygiene rules in asymptomatic contact lens wearers, and to track circulating germs in LSCs that may affect the integrity of the eye.

Methods: Demographic and behavioral data were collected from 111 asymptomatic lens wearers belonging to different medical faculties in Tunisia.
