Intermediate-term outcome of Aurolab aqueous drainage implant

PURPOSE: To report the intermediate-term safety and efficacy of Aurolab aqueous drainage implant (AADI) in patients with glaucoma. METHODS: Retrospective review of patients who underwent AADI between January 2013 and December 2016. Patients aged >16 years and with a minimum follow-up of 6 months were included. Success was defined as complete when the intraocular pressure was ≥6 and ≤21 mmHg without antiglaucoma medication and as qualified if those requiring additional antiglaucoma medications were included. RESULTS: The study included 55 patients (55 eyes) with a mean age ± standard deviation (SD) of 47.3 ± 18.1 years with a mean follow-up of 16.7 ± 11.4 months. Mean intraocular pressure reduced from 30.8 ± 11.1 mmHg to 13.1 ± 4.7, 14.1 ± 4.8, 15.7 ± 2.5 (P < 0.001) mmHg at 6 months, 1 year, and 2 years, respectively. The mean number of antiglaucoma medications reduced from 3.4 ± 1 to 0.8 ± 1.2, 0.7 ± 1.1, 0.8 ± 1 (P < 0.001) at 6 months, 1 year, and 2 years, respectively. The cumulative probability of complete and qualified success was 62% and 100% at 6 months, 54% and 92% at 1 year, and 43% and 88% at 2 years, respectively. Four patients failed during the follow-up period. Postoperative complication occurred in 28 eyes (51%), of which 17 eyes (31%) required intervention. CONCLUSION: AADI is a safe and effective treatment for the control of intraocular pressure in patients with glaucoma.
