Cataracts A review measured serum tocopherol and reported higher serum concentration was associated with a 23% reduction in relative risk of age-related cataracts (ARC), with the effect due to differences in nuclear cataract rather than cortical or posterior subcapsular cataract. In contrast, meta-analyses reporting on clinical trials of alpha-tocopherol supplementation reported no statistically significant change to risk of ARC compared to placebo.
