초록

We investigated the change in the characteristics of contact lenses according to the interpenetrating polymer network (IPN) time and method when a contact lens was dual-networked with alginate and carrageenan. The IPN was formed for four weeks using semi-IPN and full-IPN. The functions of contact lenses were assessed based on the measurement of water content, oxygen permeability, contact angle, protein adsorption, and antimicrobial. With the increase in IPN time, all physical and chemical properties of contact lenses were improved. The oxygen permeability and wettability were better when using alginate than using carrageenan. The water content and oxygen permeability were better when using the semi-IPN method than using the full-IPN method, whereas wettability was further improved when using the full-IPN method. The result of this study verified that seaweed polysaccharides were helpful in the functional improvement of hydrogel contact lenses, and performance was better in a longer IPN time.
