Chihara E, Hamanaka T. Historical and Contemporary Debates in Schlemm's Canal-Based MIGS. J Clin Med 2024; 13:4882.

Abstract
Glaucoma is one of the primary causes of blindness worldwide. Canal opening surgery, a type of minimally invasive glaucoma surgery (MIGS) applied in cases of mild to moderate glaucoma, has gained increasing popularity in recent years due to its efficacy in reducing the intraocular pressure, its safety profile, the simplicity of its technique, and the reduced likelihood of compromised vision. Nevertheless, the existing body of histopathological studies remains insufficient for a comprehensive understanding of post-surgical wound healing. Consequently, debates persist among researchers regarding the mechanism through which Schlemm's canal opening surgery reduces the intraocular pressure, as well as the surgical techniques that may impact the outcomes and the factors influencing surgical success. As the history of MIGS is relatively short and lacks sufficient systemic reviews or meta-analyses evaluating the influence of individual factors, this review was conducted to illuminate the disparities in researchers' opinions at the current stage of research.

Mou D, Wang J, Wang H, Wang N. Phacoemulsification combined with Kahook Dual Blade Goniotomy versus with Trabectome in the treatment of open angle glaucoma. Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06572-0. [PMID: 39007909 DOI: 10.1007/s00417-024-06572-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 06/26/2024] [Accepted: 07/01/2024] [Indexed: 07/16/2024] Open
Abstract
PURPOSE 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.
