목적: 본 연구의 목적은 어린이에서 누진가입도렌즈의 착용이 근시진행에 미치는 영향을 평가하고자 한다. 방법: 강원도 횡성과 충남 천안 거주 어린이 80명(8~12세, 구면굴절이상도 -50D~-5.00D)을 대상으로 누진가입도렌즈와 단초점렌즈를 무작위로 착용시켰다. 안경착용 후 2년 동안 6개월마다 조절마비하(Mydrin-P) 타각식 굴절검사(RM8800)와 안축장(IOL Master)을 측정하였다. 결과: 누진가입도렌즈착용군(42명)과 단초점렌즈착용군(38명)에서 2년간 등가구면굴절력의 변화량은 누진가입도렌즈착용군-0.85±0.50D, 단초점렌즈착용군 -1.33±0.61D로 0.48D의 유의한 차이가 있었고 (p=0.00), J0의 변화량은 각각 0.06±0.18D와 0.17±0.21로 0.11D로 유의한 차이가 있었으며(p=0.01), J45의 변화량은 각각 0.01±0.08D와 0.00±0.11로 유의한 차이가 없었다(p=0.40). 안축장의 변화량은 각각 0.45±0.24㎜와 0.67±0.73㎜로 0.22㎜의 차이가 있었으나 유의성은 없었다(p=0.07). 근시진행도는 처음 6개월이 지난후 유의한 차이가 있었고(p=0.02), 그차이는 시간이 지날수록 점차 증가하는 것으로 나타났다(p=0.00). 결론: 어린이에게 누진가입도렌즈를 착용시켰을 때 단초점렌즈와 비교하여 근시진행이 지연되는 것을 확인했다.

Purpose: To evaluate the effectiveness of progressive addition lenses on myopia progression of children. Methods: Children who live in Hoengseong country or Cheonan city with spherical refractive error between -0.50Dto -0.50D 00D wrer randomly assigned to wear Progressive Addition Lenses(PAL) or Single Vision Lenses(SVL). And we measured refractive error(cylcloplegic autorefraction) and, axial lengthe(IOL Master) at for every six months by using the RM 8800 and the IOL Master fos 2-years. Results: Between PAL group(42 subjects) and SVL group(38 subjects) that completed the 2-years study, significant differences wereas observed. First, the change of mean spherical equivalent in Pal group and SVL group was -0.85 ±0.50D and -1.33 ±0.61 Drespectively. Moreover, the change of Jo in PAL group was 0.06 ±0.18D and that of Jo in SVL group was 0.17 ±0.21D. The change of J45 in PAL group and SVL group wereas 0.01 ±0.08D and 0.00 ±0.11D respectively. Also, the change of axial length in PAL group was 0.45 ±0.24 mm and that of SVL group was 0.67 ±0.73 mm. Finally, there is a difference on myopic origression rate after six month(p=0.02), and it gradually increases as times goes by(0.00). Between PAL group and SVL group.the difference of mean spherical equivalent was 0.48D(p=0.00), and that of Jo was 0.11D(p=0.01). Those differences are statistically significant. However, the difference of J45 and that of axial length between two groups wereas 0.01D and 0.22 mm, and these are not statistically significant. Conclusions: Compared to SVL, myopia progression was found to be retarded by wearing PAL. Key words: Myopia, Progression, Progressive Addition Lenses.
