목적: 재질이 다른 하루 교체용 소프트 콘택트렌즈(daily disposable soft contact lens: DDCL)의 자각적 증상, 타각적 증상 및 눈물막을 비교하였다. 방법: 소프트 콘택트렌즈를 착용하고 있는 33명(남: 2명, 여: 31명 ; 평균 21.94±1.58세)을 대상으로 재 질이 다른 세 종류(A;Nesofilcon A, B;Omafilcon A, C;Etafilcon A)의 DDCL을 단일맹검법을 사용하여 하 루 8시간 이상 2주 동안 양안에 착용하도록 하고 콘택트렌즈 피팅상태(중심잡기, 래그, 푸쉬업 검사), 자각 적 증상의 빈도와 정도, 타각증상 및 눈물막 검사 결과를 비교하였다. 결과: 세 종류의 콘택트렌즈 모두 피팅 상태가 적합한 것으로 나타났고, A 렌즈가 다른 렌즈보다 중심이 탈이 적고(p=0.000), 래그(Lag), 푸쉬업(push-up) 움직임이 적었다(p<0.01). 자각적 증상의 빈도(frequency) 와 정도(intensity) 평가에서는 재질에 따른 차이가 없었고, 타각적 증상은 A 렌즈가 다른 렌즈보다 결막충 혈과 염색(staining)이 더 많았고(p<0.05), NIBUT(noninvasive break-up time)와 TBUT(tear break-up time)는 A 렌즈가 다른 렌즈보다 길었다(p=0.000, p=0.008). 결론: 재질이 서로 다른 세 종류의 DDCL 착용 후 재질에 따른 자각적 증상은 차이가 없었고, 눈물막 안 정성과 타각적 증상은 차이가 있었으나 눈물막 안정성, 자각적 증상 및 타각적 증상 사이에 상관성은 확인할 수 없었다.
Purpose: To compare the subjective symptoms, objective signs and tear film of three different daily disposable hydrogel contact lenses (DDCL). Methods: Thirty three(male:2, female:31; mean 21.94±1.58 years) subjects who have successfully experienced wearing soft contact lenses were refitted with three different DDCL [A (Nesofilcon A), B (Omafilcon A) and C (Etafilcon A)] randomly assigned to one of three DDCL with a subject-masked method. They were indicated to wear those DDCLs for more than 8 hours a day for two weeks, bilaterally. Assessments including contact lens fitting (centration, lag, push-up test), frequency and intensity of subjective symptoms, objective signs, and tear film test were evaluated and compared after wearing three different DDCLs. Results: The fitting of three different contact lenses were shown optimal, and A lens showed good centration, less movement in lag gaze and push-up test compared to other lenses(p<0.01). The frequency and intensity of the subjective symptoms were not statistically different between the lenses. There was significantly more conjunctival redness and staining observed in eyes wearing the A lens compared with other lenses(p<0.05), NIBUT (noninvasive break-up time) and TBUT (tear break-up time) were longer in eyes wearing the A lens than other lenses(p=0.000, p=0.008, respectively). Conclusion: Whereas subjective symptoms was not different, objective clinical symptoms and tear film stability were different after wearing three DDCLs. However, we could not find significant correlation between tear film, subjective and objective symptoms.
