Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Vitamin E (tocofersolan) has been investigated for its potential role in preventing or slowing the progression of cataracts, primarily due to its antioxidant properties. Oxidative stress is believed to contribute to lens opacification, which is the hallmark of cataracts. Several observational studies have suggested that higher dietary intake or plasma levels of vitamin E are associated with a lower risk of cataract formation. However, randomized controlled trials (RCTs) and meta-analyses have produced mixed results. For example, the Age-Related Eye Disease Study (AREDS) found no significant reduction in cataract progression with vitamin E supplementation. Other large RCTs, such as the Vitamin E and Cataract Prevention Study, also failed to demonstrate a significant protective effect.

Tocofersolan is a water-soluble form of vitamin E, which may offer higher bioavailability, but there is currently no strong evidence to suggest that it is more effective than standard vitamin E forms in cataract prevention or treatment. Overall, while the antioxidant rationale is scientifically plausible and some epidemiological data is supportive, high-quality clinical trial evidence does not robustly validate the use of vitamin E (including tocofersolan) for cataract prevention or treatment. Clinical guidelines do not currently recommend vitamin E for this purpose.
