Abstract

The purpose of this study was to investigate the cause of discomfort come from wearing of soft contact lens(SCL) exposed to fundamental cosmetics, After SCLs were smeared with skin lotion, essence lotion or nutritional cream, they were exposed to artificial tear for 7 days, and then changes of the adhered protein amount, the transmission of visible light, the wettability and the base curve were estimated. The amount of protein adhered to SCLs were increased 3 times by being exposed to fundamental cosmetics. Moreover, the transmission of visible light of SCL exposed to both nutritional cream and artificial tear was 92.8%, which was 4.7% lower than SCL exposed only to artificial tear. By being exposed to skin lotion, essence lotion or nutritional cream, the contact angle of SCLs were increased up to $7.1^{\circ}$, $7.0^{\circ}$ or $5.7^{\circ}$ and the base curve of SCLs were decreased to 3.2%, 5.1% or 8.3%, respectively.

본 연구의 목적은 기초화장품에 노출된 소프트콘택트렌즈를 착용하였을 때 나타나는 불편감의 원인을 밝히는 것이다. 소프트콘택트렌즈를 스킨로션, 에센스로션 또는 영양크림에 노출 후 다시 7일간 인공누액에 노출하여 부착된 단백질 양, 가시광선 투과도, 습윤성 및 곡률반경의 변화를 측정하였다. 소프트콘택트렌즈에 부착된 단백질 양은 기초화장품의 노출에 의해 약 3배 증가하였다. 또한 영양크림과 인공누액 모두에 노출된 소프트콘택트렌즈의 가시광선 투과도는 92.8%로 인공누액에만 노출된 소프트콘택트렌즈의 97.5%보다 4.7% 더 낮았다. 스킨로션, 에센스로션, 영양크림에 노출됨에 따라 렌즈의 접촉각은 각각 $7.1^{\circ}$, $7.0^{\circ}$, $5.7^{\circ}$가 증가하였으며, 소프트콘택트렌즈의 곡률반경은 각각, 3.2%, 5.1% 및 8.3% 더 감소하였다.
