BACKGROUND: Trabeculectomy has become a mainstream treatment in intraocular pressure (IOP) reduction for primary angle-closure glaucoma (PACG); combined trabeculectomy and cataract surgery was reported to reduce IOP and simultaneously improve vision for patients with PACG and coexisting cataract. This study was specialized to compare the efficacy and safety of combined phacotrabeculectomy with that of trabeculectomy only in the treatment of PACG with coexisting cataract. METHODS: This is a comparative case series study. Thirty-one patients (31 eyes) with PACG and coexisting cataract were enrolled. Of these, 17 underwent phacotrabeculectomy and 14 underwent trabeculectomy alone. IOP, filtering blebs, and complications were compared at the final follow-up. Complete success was defined as a final IOP less than 21 mmHg without IOP-lowering medication. RESULTS: After 10 months of postoperative follow-up, the phacotrabeculectomy and trabeculectomy groups showed no significant differences regarding IOP reduction ((20.59 ± 7.94) vs. (24.85 ± 14.39) mmHg, P = 0.614), complete success rate (88% vs. 71%, P = 0.370), formation rate of functioning blebs (65% (11/17) vs. 93% (13/14), P = 0.094), and complications (41% (7/17) vs. 57% (8/14), P = 0.380). IOP-lowering medication was not required for most of the patients in both groups. Additional surgery interventions, including anterior chamber reformation and phacoemulsification, were needed in the trabeculectomy group, whereas no surgery was needed postoperatively in the phacotrabeculectomy group. CONCLUSION: Phacotrabeculectomy and trabeculectomy treatments exhibit similar IOP reduction, successful rates, and complications when it comes to treating PACG patients with coexisting cataract, although additional surgery intervention may be needed for a few cases with cataract and complications after trabeculectomy.
