This study aimed to compare the intraocular pressure （IOP） lowering efficacy and side effects of S-2 polypropylene and PF-7 silicone AGV implantation in Chinese refractory glaucoma patients.Methods Patients were divided into S-2 model AGV group and FP-7 model AGV group. The complete and qualified surgical success rate, change of IOP, number of anti-glaucoma medications used and postoperative complications were recorded and analyzed.Results Average follow-up time was comparable between two groups. IOP was reduced from （37.9±12.7） mmHg preoperatively to （17.3±5.3） mmHg at the last follow-up in S-2 group and reduced from （39.9±14.4） mmHg to （17.7±4.9）mmHg in FP-7 group. Anti-glaucoma medications were reduced from 3.8±0.2 to 1.5±0.2 in S-2 group, and 3.5±0.2 to 0.7±0.2 in FP-7 groups. The cumulative success rates were comparable in two groups, which were 61.2% and 72.1% in S-2 group and FP-7 group respectively. When IOP reduction criteria was used, complete success rates were 30.6% and 51.2% for S-2 and FP-7 groups, and qualified success rates were 86.1% and 92.7% separately. In both groups, the major complication was hypotony, and the previous trabeculectomy of patients was the major risk factor for surgery failure.Conclusions In this short-term retrospective study, S-2 AGV is showed at least as effective as FP-7 AGV in IOP reduction, but associated with higher rate of complications. Previous trabeculectomy is a principle risk factor for AGV implantation failure. These clinical outcomes are important for converting use of the FP-7 silicon AGV in Chinese refractory glaucoma patients.展开更多
