다국어 초록 (Multilingual Abstract)

Purpose: In this study, the change of luminance transmittance and contrast sensitivity was studied by the change of UV cut-off soft contact lens according to increasing the exposure UV-A, UV-B, UV-CMethods: Luminance transmittance of two hydrogel lenses, two silicone hydrogel lenses which affected UV-A, B, C lamp was measured and the contrast sensitivity was examined to the patient 23(46 eyes)Results: The luminance transmittance of soft contact lens irradiated UV lamp greatly decreased from the lens irradiated by UV-C lamp to UV-B and UV-A.
Contrast sensitivity test was performed to experimental subjects who wore soft contact lens affected by the same amount of ultraviolet irradiation.(9.35mJ/cm2) The measured value of lens irradiated by UV-C lamp was the lowest, which was a statistically significant difference(p<0.05).
Conclusions: The change of luminance transmittance and contrast sensitivity of soft contact lens irradiated by ultraviolet A, B, C was affected by UV-C, UV-B, UV-A in regular sequence and silicone hydrogel material type was more affected than hydrogel material type.

목 적: 본 연구에서는 자외선 UV-A, UV-B, UV-C의 노출 증가에 따른 UV 차단용 소프트 콘택트렌즈의 시감투과율 및 대비감도의 변화에 미치는 영향에 대하여 연구하였다.
방 법: UV-A, UV-B, UV-C lamp의 영향을 받은 2개의 하이드로겔 렌즈, 2개의 실리콘 하이드로겔 렌즈의 시감투과율과 피검자 23명(46안)의 대비감도를 검사하였다.
결 과: UV lamp에 영향을 받은 콘택트렌즈의 시감투과율이 UV-C 조사받은 렌즈가 가장 크게 감소하였으며 UV-B, UV-A순으로 감소하였다. 동일한 자외선 양(9.35mJ/cm2)을 조사 받은 소프트 콘택트렌즈로 피검사자에게 착용 후 대비감도를 측정값은 UV-C 조사 받는 소프트 콘택트렌즈가 가장 낮게 측정되었고, 이는 통계적으로 유의한 차이를 보였다(p<0.05).
결 론: UV-A, UV-B, UV-C lamp의 영향을 받은 소프트 콘택트렌즈의 시감투과율 및 대비감도 변화는 UV-C, UV-B, UV-A lamp 순으로 영향을 많이 받는 것을 알 수 있었고, 하이드로겔 재질보다 실리콘 하이드로겔 재질이 더 많은 영향을 받은 것으로 나타났다.
