Schilcher, Jennifer Prues-Hoelscher, Kristina Spaniol and Gerd Geerling\u003Cbr>Abstract\u003Cbr>Background: Minimally invasive glaucoma surgeries (MIGS) have gained attention for their safety and efficacy, especially in clinical trials involving primary open-angle glaucoma. However, real-world data on pseudoexfoliation glaucoma (PEX glaucoma) remain limited. To our knowledge, this is the first real-world study comparing postoperative outcomes of Kahook Dual Blade Excisional Goniotomy (KDB) or trabecular aspiration (TA) in PEX glaucoma. Objective: To compare the efficacy and safety of combined clear cornea cataract extraction with either KDB or TA in patients with PEX glaucoma.\u003Cbr>Design: A retrospective analysis.\u003Cbr>Methods: We reviewed 113 eyes from 99 patients who underwent cataract surgery combined with either KDB (n = 71) or TA (n = 42) between May 2017 and May 2023 at the University Eye Hospital. Propensity score matching was used to create comparable groups of 30 KDB and 30 TA cases based on age, sex, baseline intraocular pressure (IOP), and number of glaucoma medications. Key outcomes included IOP, number of glaucoma medications, complications, and reoperations.\u003Cbr>Results: The mean patient age was 80.5 ± 7.3 years for KDB and 80.4 ± 7.7 years for TA, p = 0.94. 73.3% were women, p = 1.0. The mean baseline IOP was 20.4 ± 7.1 for KDB and\u003Cbr>20.0 ± 8.4 for TA, p= 0 .35, and the baseline number of glaucoma medications (Meds) was\u003Cbr>2.0 ± 1.2 for KDB and 2.0 ± 1.2 for TA, p= 0.78. The mean postoperative IOP at 12 months was\u003Cbr>13.5 ± 3.6 mmHg for KDB and 14.2 ± 2.6 mmHg for TA, p= 0.12, and Meds at 12 months were\u003Cbr>1.0 ± 1.2 for KDB and 1.4 ± 1.1 for TA p= 0.12. The median follow-up was 13.1 (IQR: 11.6–17. 1) months for the whole group. A total of four eyes following KDB and two after TA required additional surgery to lower the IOP.\u003Cbr>Conclusion: Both KDB and TA with cataract extraction lowered IOP in PEX glaucoma.\u003Cbr>However, KDB was associated with a higher rate of additional surgical interventions to achieve adequate IOP control.\u003Cbr>Keywords: goniotomy, Kahook Dual Blade, PEX glaucoma, trabecular aspiration\u003Cbr>Received: 24 April 2025; revised manuscript accepted: 21 November 2025. |  | TherAdv Ophthalmol 2026, Vol. 18: 1–10\u003Cbr>DOI: 10. 1177/ 25158414251405351 © The Author(s), 2026.\u003Cbr>Article reuse guidelines: [sagepub.com/journals](sagepub.com/journals)permissions\u003Cbr>Correspondence to:\u003Cbr>Alicja Strzalkowska\u003Cbr>Department of Ophthalmology, Medical Faculty and University Hospital Düsseldorf, Heinrich Heine University Düsseldorf, Moorenstreet 5, Düsseldorf 40225, Germany\u003Cbr>Alicja.Strzalkowska@ [med.uni-duesseldorf.de](med.uni-duesseldorf.de)\u003Cbr>Piotr Strzalkowski Alexandra V.
