소프트 콘택트렌즈의 새그깊이 측정에 관한 연구 = A Study on Sagittal Depth Measurement of Soft Contact Lenses

다국어 초록 (Multilingual Abstract)

Purpose : To compare the difference in sagittal depth between soft contact lenses of 15 products from 4 manufacturers sold in Korea and to find out whether the lenses are relatively steep or flat.
Methods : The sagittal depth of soft contact lenses was measured through photography using a rectangular petri dish made of polystyrene containing saline and a reference body with a reference line. The contact lenses used were 15 commercially available soft contact lenses with -3.00 D.
Results : The measured sagittal depth was 3.68±0.16 mm, showing a range of 3.42 to 3.96 mm. The calculated sagittal depth was 3.67±0.15mm, and there was a relatively large difference in some lenses. The calculated base curve for each measured sagittal depth was 8.58±0.16 mm, and the base curve suggested by the manufacturer was 8.59+0.12 mm. There was a relatively large difference in some lenses.
Conclusion : The difference in sagittal depth of 15 soft contact lens products sold in Korea could be compared, and additional information on whether the lenses were relatively steep or flat could be obtained through the measured sagittal depth and the calculated base curve.

목적 : 국내에서 판매되는 4개 제조사의 15개 제품들의 소프트 콘택트렌즈 간의 새그깊이 차이를 비교해보고 렌즈들 이 상대적으로 가파른지 혹은 편평한지에 대해 알아보고자 하였다.
방법 : 식염수가 포함된 폴리스티렌 재질의 사각페트리디쉬와 기준선이 있는 기준체를 사용하여 소프트 콘택트 렌즈의 새그깊이를 사진 촬영을 통해서 측정하였다. 사용된 콘택트렌즈는 시중에서 판매되는 -3.00 D인 15개 제 품의 소프트 콘택트렌즈이었다.
결과 : 측정된 렌즈의 새그깊이는 3.68±0.16 mm로 3.42~3.96 mm의 범위를 보여 주었다. 계산된 렌즈의 새그깊이는 3.67±0.15 mm이었고, 일부 렌즈에서 상대적으로 큰 차이가 있었다. 측정된 새그깊이 별 계산된 기 본커브는 8.58±0.16 mm이었고, 제조 회사의 제시된 기본커브는 8.59+0.12 mm 이었다. 일부 렌즈에서 상대적 으로 큰 차이가 있었다.
결론 : 국내에서 판매되는 15개의 소프트 콘택트렌즈 제품들의 새그깊이 차이를 비교할 수 있었고, 측정된 새 그깊이와 그에 따른 계산된 기본커브를 통해 렌즈들이 상대적으로 가파른지 혹은 편평한지에 대한 추가적인 정보 를 얻을 수 있었다.
