PURPOSE: The outcome of XEN implantation in Chinese eyes has not been previously reported. The purpose of our study is to evaluate the efficacy and safety of combined cataract surgery and XEN implantation in Chinese eyes with glaucoma. METHODS: We conducted a prospective study of 31 consecutive Chinese patients who underwent combined phacoemulsification and XEN implantation at the National University Hospital (Singapore) in this study. Patients were assessed preoperatively and postoperatively on days 1 and 7, and months 1, 3, 6, and 12. The intraocular pressure (IOP), glaucoma medication use, Snellen visual acuity (VA), and complications were assessed at each visit. The Wilcoxon signed rank test for non-parametric data was used for the analysis of IOP and glaucoma medications at baseline versus 12 months after the procedure. RESULTS: The mean age of the patients was 70 ± 7.9 years and 48.4% were male. Twelve patients (38.7%) were diagnosed with primary open angle glaucoma and 19 patients (61.3%) were diagnosed with primary angle closure glaucoma. There was a significant decrease in IOP at 12 months (12.1 ± 2.6 mmHg) compared with preoperative medicated (15.6 ± 2.7 mmHg, p < 0.0001) and unmedicated IOP (22.1 ± 3.6 mmHg, p < 0.001). as well as a significant reduction in the number of glaucoma medications (1.4 ± 0.6 vs 0.1 ± 0.4, p < 0.0001). The most common complications were transient hypotony (12.9%) and ptosis (12.9%) and there were no sight-threatening intraoperative or postoperative complications. One patient required additional glaucoma surgery for uncontrolled IOP at 8 months after combined phacoemulsification and XEN implantation. CONCLUSION: Combined XEN implantation with cataract surgery was effective in lowering the IOP and the number of glaucoma medications in Chinese eyes for at least 12 months, with a favorable safety profile.
