Abstract:
Background: Age-related cataract is one of the most important causes of preventable blindness among elderly population in the world. Among various causes of cataract, the level of ascorbic acid in the plasma and aqueous humor is an important parameter that can prevent cataract formation. The level of ascorbic acid in the plasma and aqueous humor is also an indicator of various morphological pattern of cataract.
 Materials and Methods: A hospital-based cross-sectional study was conducted among 136 patients with immature age-related cataract (≥50 years) who underwent Manual Small Incision C

Lab prepared Triphala ghrita was studied for its possible anticataract activity on galactose induced cataract in Swiss albino rats. Administration of Triphala ghrita at a dose of 216 mg/200 g, 1080 mg/200 g and 2160 mg/200 g of rat orally offered significant dose dependent protection against galactose induced cataract and delayed the onset and progression of cataract. It was seen that the dose of 1080 mg of Triphala ghrita did not show stage II cataract in 14 days and stage III in 21 days. It did not show even stage III and stage IV cataract after 30 days whereas group B and group C showed sta
