To compare the outcomes of Paul (PGI) and Ahmed glaucoma implants (AGI) in patients with complex glaucoma.

64 patients undergoing PGI and 40 patients undergoing AGI were included in this study. Intraocular pressure (IOP), the number of IOP-lowering eye drops, and complications were evaluated during an 18-month follow-up.

At 18 months, follow-up was completed by 26 patients (65.0%) in the AGI group and 45 patients (70.3%) in the PGI group. IOP was significantly reduced 18 months following PGI (12.3 ± 4.0 vs. 28.0 ± 9.3 mmHg, p  Conclusion

Both PGI and AGI effectively reduced IOP and the number of IOP-lowering eye drops over an 18-month follow-up period. The PGI demonstrated significantly greater reductions in IOP and IOP-lowering eye drops than AGI at 18 months. The safety profiles of PGI and AGI were comparable.
