Results – cont. From retrobulbar to topical anesthesia 2009:

Results – cont. Endophthalmitis Israel is a “closed system” all cases: were operated in Israel stayed in Israel during the endophthalmitis were treated in the university hospitals A decrease in the endophthalmitis rate: From 0.24% (2000) to 0.05% (2009)

Results – cont. Intracameral antibiotic injection at the end of surgery: Wide acceptation since 2006 (94% at 2009) Since 2006 worse VA results of endophthalmitis cases

Conclusion During the last 20 years we found:  Continuous increase in cataract surgeries annual number surgeries annual number  Progression in cataract surgery technique technique  Decrease in the severe complication rate (i.e. endophthalmitis) rate (i.e. endophthalmitis)
