Abstract: The aim of this study was to investigate the occurrence of endophthalmitis after cataract operation in a population living under substandard social-economic conditions and to answer the question of whether any corellations exist between the surgical technique applied and the development of postoperative endophthalmitis.

Methods: 2446 cases of cataract extraction (using either extracapsular extraction (ECCE) or phacoemulsification) have been evaluated at the Eye Clinic of the General Hospital of Komotini, between January 1996 and January 1999.

Conclusions: The overall occurence of endophthalmitis following cataract extraction was 0,81% (20/2446). The occurence when using extracapsular extraction (ECCE) was 1.12% (12/1055) whereas after phaco-emulsification it was 0.57% (8/1391). The mean period before the appearance of postoperative endophthalmitis following phaco-emulsification and ECCE was 23 and 73 days respectively.

Discussion: We tested this difference statistically and found it significant. Endophthalmitis appears to develop significantly later when ECCE has been used comparing to phacoemulsification. This is because factors influencing endophthalmitis development, such as hygiene conditions, can be easier controlled in the case of phacoemulsification. Conclusively, in order to reduce the occurrence of postoperative endophthalmitis after cataract extraction in patients living under substandard conditions, phacoemulsification should be prefered over ECCE.
