Anterior chamber aspirate cultures were done for 66 patients who underwent either an uncomplicated intracapsular cataract extraction, extracapsular cataract extraction with posterior-chamber intraocular lens implantation, or phacoemulsification with posterior-chamber intraocular lens implantation. The aspirate was obtained at the time of wound closure. The aspirates were immediately transferred to the microbiology laboratory where one drop of the aspirate was placed on a glass slide for gram stain, and the remainder was unequally divided and inoculated into blood agar, chocolate agar and thioglycolate broth. The cultures were incubated at 37 degrees C with 5% CO2 and held for 5 days. Of 66 patients 4 (6%), had smear-positive anterior chamber aspirates. None of the aspirates showed any growth on any of the 3 culture media used. None of the eyes in the study developed endophthalmitis. This study concludes that there is no contamination of the anterior chamber by viable bacteria after cataract surgery, irrespective of the mode of intervention.

Anterior chamber aspirate cultures were done in 57 patients who underwent uncomplicated manual small incision cataract surgery with posterior chamber intra-ocular lens implantation. The aspirates were collected at the time of wound closures. The specimens were immediately inoculated into blood agar, chocolate agar and thioglycolate broth. The cultures were incubated at 37 degrees C with 5% CO2 and held for 5 days. Out of 57 patients 8 (14%) had culture positive anterior chamber aspirates. Coagulase negative staphylococcus was the commonest (62%). No anaerobic organism was detected. None of the eyes developed endophthalmitis. The study concluded that the strict aseptic measures, the antimicrobial property of the aqueous humour or small inoculum size could be the possible factors to prevent fulminating infection.
