콘택트렌즈의 교정굴절력을 결정하기 위한 over-refraction에서 자각적 굴절검사와 타각적 굴절검사의 오차 발생분포를 평가하기 위해, 교정시력이 1.0 이상이고 콘택트렌즈 착용 경험이 있는 40명 80안(남 23명, 여 17명, 24.6±2.9세)을 대상으로, 물성이 다른 5종의 콘택트렌즈를 이용하여 렌즈 착용 전과 착용 후 자각적 굴절검사와 자동굴절검사를 실시하였다. 콘택트렌즈의 처방은 교정굴절력이 ±3.00D 이상인 경우 정점간거리를 보정하였고, 등가구면굴절력을 적용하였다. 5종의 콘택트렌즈를 착용한 상태에서 자각적 굴절검사와 자동굴절검사로 over-refraction을 실시한 결과, 구면굴절력은 하루용 소프트콘택트렌즈(p
In order to evaluate the availability of auto-refractometer that determines corrective power of contact lens in the process of over-refraction, 40 people(23 males, 17 females, total 80 eyes, the average age 24.6±2.9 with corrected visual acuity over 20/20 and the history of wearing contact lens) have been tested in subjective refraction, auto-refraction both without wearing contact lens and with wearing 5 different types of contact lenses. Contact lens power was determined in consideration of calculation for correction of vertex distance and spherical equivalent power in cases of that the corrective power was over ±3.00D and astigmatism. In over-refraction by subjective refraction and auto-refraction with wearing 5 different types of contact lens, the difference of a measured values between subjective refraction and auto-refraction was significantly different in spherical power of one-day soft contact lens(p
