Phacoemulsification combined with Kahook Dual Blade Goniotomy versus with Trabectome in the treatment of open angle glaucoma.

To compare the surgical effectiveness and safety of phacoemulsification combined with KDB (Phaco-KDB) and with Trabectome (Phaco-Trabectome) at 6 months follow-up in patients with open-angle glaucoma (OAG) METHODS: This comparative case series was conducted at Beijing Tongren Hospital, including patients diagnosed with OAG who underwent Phaco-KDB from November 2021 to April 2022 and Phaco-Trabectome from April 2017 to December 2017. Surgical success was defined as an IOP reduction ≥ 20% or a postoperative IOP ≤ 21 mmHg. Kaplan-Meier methods were used to calculate cumulative rates of success among groups RESULTS: A total of 35 eyes from 29 patients were included in the analysis. At 6-month, Both groups exhibited a significant reduction in IOP and the number of IOP-lowering medications compared to preoperative (P=0.01 and P<0.01, respectively). There were no significant differences among groups in terms of reducing IOP and the number of IOP-lowering medications (all P values<0.05). In the Phaco-KDB and Phaco-Trabectome groups, 53.8% and 45.0% of patients achieved an IOP reduction of ≥ 20%, while 92.3% and 85% achieved a mean IOP ≤ 21 mmHg 6 months after surgery. The incidence of IOP spike was 20%, and 3 eyes (8.6%) needed further surgery to control the IOP CONCLUSIONS: Both Phaco-KDB and Phaco-Trabectome demonstrate a significant reduction in IOP and the number of IOP-lowering medications. Phaco-Trabectome appears to provide a more predictable postoperative course in the early postoperative period compared to Phaco-KDB, and the postoperative mean IOP is lower in Phaco-KDB compared to Phaco-Trabectome, despite not being statistically significant.
