Seaweed Polysaccharide Coating Effect of Contact Lenses Containing Lutein

To evaluate the physical properties and antioxidant duration of contact lenses by room temperature polymerization of hydrogel contact lenses containing lutein, a natural antioxidant, and layer by layer (LBL) coating with seaweed polysaccharide. A contact lenses containing lutein was coated with alginate and carrageenan. Drug release was calculated by measuring absorbance. To evaluate the physical properties of contact lenses, water content, contact angle, and oxygen permeability were measured, and surface analysis was conducted. LBL coating with seaweed polysaccharide on contact lenses containing lutein improved water contents, wettability, and oxygen transmissilility. It was found that the antioxidant duration increased as the LBL layer by seaweed polysaccharide was formed, and the duration increased further as the metal ion was added. It was confirmed that the antioxdant duration and physical properties were improved by forming the LBL coating layer with seaweed polysaccharide containing lutein.
