PURPOSE: To compare the outcomes of phakic, pseudophakic and combined phaco-trabeculectomy in eyes of Saudi patients. METHODS: This was a retrospective cohort study. Eyes of patients with primary open angle glaucoma, primary angle closure glaucoma or secondary exfoliation glaucoma (XFG) that underwent phakic (n = 152), pseudophakic (n = 40) or combined phaco-trabeculectomy (n = 45) at the King Khaled Eye Specialist Hospital, Riyadh from January 2012 to December 2017 were included. The primary outcome measure was the success at 3 years after surgery. Complete success was defined as achieving an intraocular pressure (IOP) of ≥ 6 and ≤ 21 mmHg without topical antiglaucoma medications; qualified success as achieving the same IOP criteria with or without the use of glaucoma medications. Cumulative probabilities of failure were computed using Kaplan-Meier survival analysis. We used Cox regression analysis to identify factors associated with treatment failure. Reduction in mean IOP and AGM over time was estimated using mixed-effects linear models. RESULTS: The mean decrease in IOP at 3 years from baseline in the phakic, pseudophakic and combined groups was 12.0 (95% CI, 9.9, 14.1) mmHg, 10.1 (95% 6.3, 13.9) mmHg, and 6.4 (95% CI, 1.9, 11.0) mmHg, respectively, and was not significantly different from each other. The values for qualified success were also comparable: 95.2% (95% CI: 86.7-99.0), 95.3% (95% CI: 76.2-99.9), 92.3% (95% CI: 64.0-99.8). Failure was significantly associated with postoperative suturelysis (p = 0.004), XFG (p = 0.018) and AGM (p = 0.038). CONCLUSIONS: This is the first study to provide relative surgical outcomes of trabeculectomy, phaco-trabeculectomy and pseudophakic trabeculectomy in Saudi Arabia and did not show any significant difference in terms of overall success.
