Abstract

Aim: To evaluate the short-term efficacy of XEN45 Gel Stent (XEN) implantation for primary open angle glaucoma (POAG) and pseudoexfoliation (PEX) glaucoma across two university eye clinics, aiming to assess the impact of varying center-specific protocols during the first postoperative year.

Methods: We retrospectively examined 282 patients (183 in center 1, 99 in center 2), who underwent XEN microstent implantation for uncontrolled POAG or PEX glaucoma. Parameters including intraocular pressure (IOP), IOP-lowering medication count, best corrected visual acuity (BCVA), and postoperative complications were evaluated over 12mo.

Results: Post-implantation, center 1 reported a mean IOP reduction from 25.3±7.4 to 14.1±4.7 mm Hg (P<0.01) and a decrease in IOP-lowering medications from 3.2±1.2 to 1.0±1.3 (P<0.01). Center 2 observed a similar reduction from 24.4±6.5 to 15.1±5.5 mm Hg (P<0.01) and medication decrease from 3.0±1.1 to 1.2±1.0 (P<0.01). BCVA remained stable in both cohorts. The most common complications were hypotony (center 1: 32; center 2: 20) and choroidal detachment (center 1: 22, center 2: 15), with nearly identical needling rates (40% in center 1, 41% in center 2).

Conclusion: XEN implantation yields consistent reductions in IOP and medication use across different centers using comparable surgical and postoperative treatment regime. These findings underscore XEN's short-term effectiveness and suggest standardizable outcomes regardless of exact surgical procedure or treatment differences.

评估XEN微支架一年的疗效：独立于部位变异性。

目的：评估两所大学眼科诊所XEN45凝胶支架（XEN）植入术治疗原发性开角型青光眼（POAG）和假性脱落型青光眼（PEX）的短期疗效，旨在评估不同中心特异性方案在术后第一年的影响。方法：我们回顾性研究了282例（中心1 183例，中心2 99例）接受XEN微支架植入术治疗不可控POAG或PEX型青光眼的患者。随访12个月，评估眼压（IOP）、降眼压药物计数、最佳矫正视力（BCVA）及术后并发症。结果：植入术后，中心1报告平均IOP从25.3±7.4降至14.1±4.7 mm Hg （ppppp）。结论：不同中心采用相同的手术和术后治疗方案，XEN植入术的IOP和药物使用降低一致。这些发现强调了XEN的短期有效性，并提出了标准化的结果，而不考虑确切的手术程序或治疗差异。
