Purpose: Postoperative endophthalmitis, although a rare occurrence, is one of the most serious and potentially devastating complications after cataract surgery. Our aim is to compare the incidence rate of post–operative endophthalmitis after cataract surgery in three teaching hospitals in the UK, Sri Lanka and Paraguay. Methods: This is a retrospective case note study looking at the demographics, various sterilisation techniques and the incidence of post–operative severe infection within a three month follow up period in the three centres. Results: Over a twelve month period between December 2003 and November 2004, over 8900 cataract surgeries were reported from Sri Lanka, around 2000 from Paraguay and approximately 2200 cataract surgeries were performed in the UK. Of these, 18 cases (0.202%) of endophthalmitis were reported from Sri Lanka, 1 case (0.048%) from Paraguay and 3 cases (0.15%) in the UK. While an elaborate and expensive method of asepsis is practised in the UK, only basic sterilization techniques are performed in Paraguay and Sri Lanka . Conclusions: There seems to be a wide variation in sterilisation techniques in different parts of the world. In the developed countries like the UK, a significant amount of resources have been invested into developing expensive sterilization and surgical techniques as well as disposable materials in order to reduce the incidence of postoperative endophthalmitis. In spite of the lack of these resources and less stringent criteria for asepsis, the incidence of postoperative endophthalmitis in the developing countries seems to be quite low and well within the limits reported internationally.
