The antioxidant eye drops is a topical ophthalmic formulation that contains four nutraceuticals (namely, astaxanthin, resveratrol, pyruvate and epigallocatechin gallate (EGCG)) having antioxidant, anti-inflammatory, and chelating activity in a carbomer gel carrier. The active ingredients can reduce oxidative stress through free radical scavenging and chelating activity. The carrier is composed of a solution of deionized water containing about 0.4% Carbopol 980 NF, 5.7% sorbitol. 0.01% cetrimide, 0.01% EDTA, and sodium chloride and sodium hydroxide in adequate amounts to adjust both the viscosity and the pH of the topical carrier to pH 7.0-7.4. Use of the formulation may delay the development of cataracts, reduce retinal degeneration, and maintain normal tear flow in dry eye due to the antioxidant, anti-inflammatory, and chelating activity of the active ingredients.
