Abstract

The functional acryl hydrogel contact lenses have attracted great attention because of their superior antioxidant and antifouling activities, resulting that they can be worn for a long time. In this study, acryl hydrogel contact lenses coated with phosphorylcholine polymer and EGCG, such as MPC2EG and MPC4EG, were prepared to improve antioxidant and antifouling activities. The resulting contact lenses exhibited higher optical transparency, oxygen permeability, and blue light blocking ability compared with PHEMA lens. In addition, they exhibited highly enhanced radical scavenging activity and antifouling activity. They removed most of DPPH and ABTS radical, and the suppressed the adhesion of albumin, lysozyme, and γ-globulins on the surfaces of contact lenses. In particular, they displayed superior antimicrobial activities against Staphylococcus aureus and E. Coli.


항산화성과 단백질 흡착 억제능이 극대화된 기능성 아크릴 하이드로젤 콘택트렌즈는 부작용 없이 장시간 착용이 가능하기 때문에 최근 많은 관심을 받고 있다. 본 연구에서는 포스포릴콜린 고분자와 천연 폴리페놀인 에피갈로카테킨 갈레이트(EGCG)로 렌즈 표면을 코팅함에 의해서 항산화성과 단백질 흡착 억제능이 극대화된 아크릴 하이드로젤 콘택트렌즈인 MPC2EG 및 MPC4EG를 제조하였다. 제조된 콘택트렌즈는 높은 광학 투명도를 보였으며, 코팅 처리하지 않은 PHEMA 렌즈 대비 높은 산소투과율과 청색광 차단율을 보였다. 또한 여러 종류의 라디칼에 대해서 매우 뛰어난 라디칼 제거능을 보였고, 다양한 단백질에 대해서는 우수한 단백질 흡착 억제능을 보였다. 특히 감염성 안질환 원인균인 포도상구균과 대표적인 그램 음성균인 대장균에 대해서 매우 우수한 항균성을 보였다.
