AIMS: To compare success proportions at 5 years in three surgical groups: group 1, trabeculectomy alone; group 2, trabeculectomy followed by cataract surgery within 2 years; and group 3, trabeculectomy performed on a pseudophakic eye. METHODS: A retrospective cohort study. 194 eyes of 194 patients were identified with at least 5 years' follow-up post trabeculectomy (N=85, 60 and 49 in groups 1, 2 and 3, respectively). MAIN OUTCOME MEASURES: 1. PRIMARY OUTCOME MEASURE: intraocular pressure (IOP) at 5 years post-trabeculectomy surgery, 2.Secondary outcome measure: change in visual acuity at 5 years. RESULTS: At 5 years, the mean IOP (SD) was 12.9 (3.5), 12.5 (4.8) and 12.7 (4.8) mm Hg in groups 1, 2 and 3, respectively. Overall success was almost identical, 58%, 57% and 59% in groups 1, 2 and 3, respectively. There was no significant difference between the groups in terms of percentage IOP reduction, number of medications, proportion restarting medication and reoperation rates at 5 years. Logistic regression for an outcome of failure showed men to be at increased risk of failure OR 1.97 (95% CI 1.10 to 3.52, p=0.02). Nearly 80% of patients retained or improved their vision following their initial trabeculectomy. CONCLUSIONS: The sequence in which surgery is carried out does not appear to affect trabeculectomy function at 5 years, success being similar to trabeculectomy alone. In our study, men may be at increased risk of failure.
