Four cases of endophthalmitis following ECCE with IOL were identified from a total number of 5453 cases ; one case of post-trabeculectomy endophthalmitis was found from a total number of 1092 cases, and endophthalmitis occurred in one case among the one-hundred and two cases in which phacoemulsification with IOL was performed. Positive vitreous cultures yielded acenetobacter in one case and proteus milabilis in another.

The final visual outcome was devastating in all but one case in which the final vision was 20/30. Potential risk factor were carefully reviewed including, for example, prolonged operating time and uncleared air-conditioning ventilation. Improper steritization of surgical instruments was a significant finding. Literature review of comparable studies was also provided.
