Microbial changes in the ocular environment with contact lens wear.

摘要: A group of 30 subjects, each fit with a single disposable or non-disposable soft contact lens, was further randomized to daily wear extended schedule determine the effect lens on normal conjunctival flora. Cultures subjects' inferior cul-de-sacs were taken at baseline before any and after one week wear. Additionally, removed in sterile manner cultured end period. In all fellow eye used as control. There no statistically significant differences respect bacterial culture results between experimental control eyes. Also, there pre- post-lens groups. And found when larger groups broken down into different schedules types compared. The this study suggest that ocular flora is not markedly changed Also raised question whether an altered etiologic factor development infectious keratitis wearers.
