Popis: Purpose: To compare the surgical outcomes of twin-site phacotrabeculectomy with Mitomycin C (MMC) in primary open-angle glaucoma (POAG) versus primary angle-closure glaucoma (PACG). Methods: Prospective, comparative, observational study. Patients with visually significant cataract and primary glaucoma were divided into two groups: POAG and PACG. They underwent twin-site phacotrabeculectomy with MMC and followed up on days 1, 15, 1 month, 6 months, and 12 months. Baseline and follow-up visits were compared to find the differences in intraocular pressure (IOP), antiglaucoma medications (AGM), success rates, anterior chamber depth (ACD), and axial length (AXL). Results: There were 50 eyes each in POAG and PACG groups. Mean IOP reduction from baseline to 12 months (21.22 ± 6.0 to 11.40 ± 2.8—POAG group vs 24.16 ± 7.6 to 12.42 ± 3.2—PACG group) was statistically significant in both groups (P < 0.001), but no significant difference between groups (P = 0.095). There was a statistically significant decline in the number of AGM in POAG [1.66 (0.7) to 0.38 (0.7), P < 0.001] and PACG [2.10 (0.7) to 0.70 (0.8), P < 0.001]; the decline was more in POAG (P = 0.012) at last visit. Probability of overall (complete and qualified) success at 12 months postop was 72.0% [95% confidence interval (CI): 57.4–82.4] in PACG and 84.0% (95% CI: 70.5–91.7) in POAG group. There was a significant increase in ACD and a decrease in AXL in both groups (P < 0.001). More interventions were required in the PACG group (38, P = 0.012). Conclusion: Phacotrabeculectomy with MMC causes a significant reduction in IOP and improvement in biometric parameters in both POAG and PACG. Patients with PACG required more postoperative interventions, while a lesser number of antiglaucoma medications were needed in POAG patients.
