Abstract

As life expectancy increases worldwide, the incidence and prevalence of age-associated cataract do and impair the daily activities of millions. Correction is poor and surgery remains the most common solution, albeit out of reach for the vast majority of (poor) mankind. Reports on the efficacy of traditional Asian medicines (Chinese = TCM; Japanese = kampo) prompted us to evaluate a widely available/affordable TCM formula (GFDHW) in aged (≥ 60) subjects recruited from the Optometry Clinic of HKPU; 30 were enrolled and 22 completed the course. These subjects presented with mild cataract without any other significant health problem. After 90 days of GFDHW we did not observe any effect on the development and/or progression of cataract. However, a number of subjects reported improvement in areas of their "quality of life". A pronged, placebo-controlled and comparative (e.g. Bawei Dibuang) study seems warranted.
