Methods: Clinically presumed case s of POE were reported in a prospective survey involving all Swedish ophthalmic surgical units except one. Data on results of the intraocular culture and visual outcome after infection, as well as patient age and gender and various elements of the surgical procedure, were collected. Results: The nationwide incidence of POE was 0.0595%, representing 112 cases in 188 151 cataract operations. Gram- positive bacteria were the predominant aetiology, with an 84.6%share of culture -positive cases. A significantly decreased risk for POE was found for patients who had received prophylactic intracameral antibiotics (mainly cefuroxime) in co mparison with those who had been treated with topical antibiotics only. Conclusi ons: The prevalence of POE after cataract surgery in Sweden is at the lower end of the spectrum of incidence currently reported in the developed world. The admi nistration of intracameral antibiotics may have contributed to these results.展开更多

Methods: Patients’self assessed visual function was evalua ted using the Catquest questionnaire both before and 6 months after a cataract e xtraction. The study population consisted of 615 patients undergoing a cataract extraction during 1995-2002. A final follow up with a new questionnaire was per formed in 2003, between 1 year and 8 years after surgery. Results: 445 (72.4%) patients were alive at follow up and agreed to participate in the study. The num ber of subjects still showing improved visual function after surgery decreased w ith longer follow up. After 7 years, 80%had improved visual function compared w ith before surgery. 50%of all originally operated subjects were alive 7 years p ostoperatively and enjoyed better visual function than they had done before surg ery. Ocular co-morbidity in the operated eye or self assessed poor visual funct ion before surgery was significantly related to deteriorated visual function at follow up. Conclusion: The number of subjects who experienced improved visual fu nction after a cataract extraction decreased over the course of time postoperati vely. Presence of ocular co-morbidity was significantly related to worsened fun ction.展开更多
