Lens Opacity Clinical Trial
Official title:
Effects of Vitamin C and Lycium Barbarum Supplements on the Progression of Senile Cataract in Hong Kong Chinese Population
With the rapid growing aging population, age-related eye diseases including cataract are
becoming more prevalent. The demand for cataract surgery and post-surgical care posed
enormous financial burdens to the government.
Vitamin C, also known as ascorbate, is a highly effective antioxidant which may help to
protect the cells including the crystalline lens components from oxidative damage, which is
believed to be one of the causes of senile cataract.
Lycium barbarum, on the other hand, contains lutein and zeaxanthin which can filter the
phototoxic blue light and neutralize the reactive oxygen species, thus provide a protective
effect against cataract formation.
This study aims to determine the effects of Vitamin C and Lycium barbarum Supplements on the
progression of senile cataract in Hong Kong Chinese elderly.
