Intermediate-term outcome of Aurolab aqueous drainage implant

ABSTRACT

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.
