AbstractPurposeReport annual benchmark exercise of aqueous shunt implants (tubes) outcomes and risk factors for failure over 4 years.MethodsRetrospective cases series: Annual reporting of outcomes of tube implants. A total of 332 eyes were included in this study. The main outcomes were intra‐ocular pressure (IOP), loss of visual acuity (VA), number of medications and failure/visually threatening complications at 1‐year follow‐up.ResultsSurgical success rate was 93% at a mean follow‐up of 13.3 months. Compared to preoperative IOP (25.8 ± 7.9 mmHg), the mean postoperative IOP was significantly lower (14.4 ± 5.5 mmHg, p < 0.00001) on significantly fewer ocular hypertensive medications (from 3 ± 1 to 1.4 ± 1.3, p < 0.00001). There were 2 (0.6%) cases of loss of light perception.ConclusionAnnual reporting of tube implant within a service provides an exceptional tool for monitoring outcomes in line with major literature. It allows to monitor safety as well as new trends in surgical technique.
