Bacteriological studies on the conjunctival sac of cataract patients.

Seventy-five per cent of the patients undergoing cataract operation harboured microorganisms in their conjunctiva, out of which 40 per cent were pathogenic species. Preponderance of Moraxella was encountered. One third of the pathogenic microorganisms were found to be resistant to most of the antibiotics except Gentamycin. Positive conjunctival cultures were also obtained from 70% controls and 50% staff members. Pathogens were isolated in 25% controls and 8% staff members. Preoperative determination of conjunctival microorganisms and administration of appropriate antibiotics may reduce post operative complications(JPMA 31:10,1981).
