미세먼지 농도가 소프트콘택트렌즈 착용에 미치는 영향 = Effects of Particulate Matter Concentration on Wearing Soft Contact Lenses

국문 초록 (Abstract)

목적: 미세먼지 농도에 따른 소프트콘택트렌즈의 파라미터, 눈물막 안정성 및 자각증상 변화에 대해 알아보고자하였다. 방법: 미세먼지 농도가 보통인 날과 나쁜 날 각각 8시간 동안 20안에 etafilcon A 재질의 일일 착용 소프트콘택트렌즈를 착용하도록 하였다. 소프트콘택트렌즈를 착용하기 전과 각각의 농도에서 착용 후의 비침입성 눈물막파괴시간을 확인하였으며, 소프트콘택트렌즈의 전체직경, 곡률반경, 중심두께, 굴절력, 가시광선 투과율, 산소투과도와 같은 파라미터 및 자각증상을 측정하였다. 결과: NIBUT와 전체 자각증상은 미세먼지 농도에 따라 통계적으로유의하게 변하였다. 소프트콘택트렌즈 파라미터의 변화 정도는 차이가 적었고 통계적으로 유의하지 않았다. 미세먼지 농도가 높은 날에 더 크게 나타난 전체 자각증상의 변화는 눈의 불편 증상 보다는 전신 증상의 영향을 더 많이받았다. 결론: 본 연구를 통해 미세먼지 농도가 일일 착용 소프트콘택트렌즈 착용 시의 관련 자각증상에 영향을 미침을 밝혔다. 미세먼지 환경에서의 안전하게 소프트콘택트렌즈를 착용하기 위해 미세먼지에 반복적으로 장시간 노출되었을 때 유발되는 문제점과 소프트콘택트렌즈 재질에 따른 차이에 대한 연구가 추후에 진행될 필요가 있음을제안한다.

Purpose: This study was aimed to investigate the changes of soft contact lens parameters, tear film stability and subjective symptoms according to the concentration of the particulate matter. Methods: 20 eyes wore etafilcon A oneday disposable soft contact lenses for 8 hours on both usually and poor days of concentration of the particulate matter.
The non-invasive tear film break up time (NIBUT) was measured before and after wearing the soft contact lens on each day and the parameters such as total diameter, back optic zone radius, center thickness, refractive power, visible light transmittance, oxygen permeability, and subjective symptoms were measured. Results: NIBUT and overall subjective symptoms score were significantly different according to the concentration of the particulate matter. The degrees of change in parameters of the soft contact lens were little and were not significantly different. Changes in overall subjective symptoms, which were greater on the day when the particulate matter density was high, were more affected by systemic symptoms than by the symptoms of eye discomfort. Conclusions: This study showed that the particulate matter concentration affects the related symptoms when wearing one-day disposable soft lenses. It is suggested that further studies on the problems caused by repeated exposure to the particulate matter for a long period of time and the difference according to the soft contact lens material need to proceed in order to safely wear soft contact lens in the particulate matter environment.
