Anterior chamber fluid contamination after uncomplicated phacoemulsification

This study determined the rate of anterior chamber aerobic bacterial contamination in 103 eyes that had uncomplicated posterior chamber phacoemulsification. Anterior chamber fluid was aspirated on completion of surgery. Cultures of sterile balanced salt solution served as a control. Of 103 anterior chamber cultures, 4 (3.9%) showed contamination; however, 3 of 103 control cultures (2.9%) also grew micro-organisms. These findings suggest a very low rate of aerobic bacterial contamination after uncomplicated phacoemulsification and underscore the importance of control cultures when determining contamination rates.
