Mingmu Dihuang Tang (MDT), a traditional Chinese medicine formula, is postulated to offer antioxidative and anti-inflammatory benefits in this context. Objectives: This study evaluated the clinical efficacy of MDT as an adjunctive therapy for antioxidant and anti-inflammatory effects in elderly patients after cataract surgery. Methods: In this randomized controlled trial, 120 patients were allocated to either a control group receiving conventional Western medicine or an experimental group receiving conventional treatment plus MDT. Serum and aqueous humor levels of glutathione peroxidase (GSH-Px), catalase (CAT), superoxide dismutase (SOD), total antioxidant capacity (TAC), nitric oxide and inflammatory cytokines (IL-2, IL-6, TNF-α) were measured. Visual acuity and lens opacity were also assessed. Results: Compared with the control group, the experimental group demonstrated significantly higher antioxidant activities (GSH-Px, CAT, SOD, TAC) and IL-2 levels, along with lower nitric oxide, IL-6 and TNF-α concentrations (P<0.05). The MDT group also showed better visual acuity recovery, reduced lens clouding and a lower complication rate. Conclusion: Adjunctive therapy with MDT enhances antioxidant capacity, modulates inflammation and improves clinical outcomes in cataract surgery recovery, indicating potential clinical value. ER -
