초록

목 적 : 근시정도에 따라 역기하렌즈(reverse geometry lens), MC렌즈(myopia control lens), 단초점렌즈(single vision lens)를 착용 한 후의 근시진행억제 효과에 대한 굴절교정 값의 변화를 단초점렌즈와 비교해 알아보고자 한다.
방 법 : 7세에서 15세 사이의 아동에게 역기하렌즈를 57안, MC렌즈를 56안, 단초점렌즈를 78안 착용시킨 후 근시정도에 따라 3그룹으로 나눴다. 그룹 1은 교정굴절력이 S–2.00D 이하 근시안과 그룹 2는 S-2.25D 이상에서 S–4.00D 이하의 근시안, 그룹 3은 S–4.25D 이상의 근시안으로 나눈 뒤 12개월 이하, 13~24개월, 25~36개월의 굴절교정 값의 변화를 통한 근시 진행 억제 효과를 알아보고 이에 대한 추적 결과의 통계적 유의성을 검증하고자 하였다.
결 과 : 근시정도에 따라 그룹 1에서 36개월 동안 역기하렌즈는 S-0.11±0.32D(P>0.05)로 증가했지만 통계적으로는 유의하지 않았고, MC렌즈는 S-0.58±0.32D(P<0.05), 단초점렌즈는 S-1.50±0.47D로 통계적으로 유의(P<0.05)하게 증가하였다. 그룹 2에서는 36개월 동안 역기하렌즈가 S-0.45±0.78D로 증가했지만 통계적으로는 유의(P>0.05)하지 않았고, MC렌즈가 S-1.06±0.68D(P<0.05), 단초점렌즈는 S-1.95±1.07D로 통계적으로 유의(P<0.05)하게 증가하였다. 그룹 3에서는 36개월 동안 역기하렌즈가 S-0.15±0.39D로 통계적으로 유의(P>0.05)하지 않았고, MC렌즈가 S-1.02±0.42D(P<0.05), 단초점렌즈가 S-1.77±0.74D로 유의(P<0.05)하게 변화하였다.
결 론 : 근시정도에 따른 굴절교정 값의 변화는 약도근시에서 고도근시까지 역기하렌즈가 변화의 증가가 낮아 근시진행억제 효과가 있었으며 MC렌즈는 근시진행억제 효과가 역기하렌즈 보다 낮았고 단초점렌즈보다 높았으며 S–2.00D 이하 근시안에서 가장 높은 근시진행 억제 효과가 있는 것으로 나타났다.

Purpose : To learn the changes of refractive correction value regarding effects of inhibiting myopia progression after wearing the reverse geometry lens, myopia control lens and single vision lens, by degree of myopia, in relation to those after wearing the single vision lens.
Method : Children between the ages of seven and fifteen were organized into three groups according to their degree of myopia and were given fifty-seven reverse geometry lenses, fifty-six MC lenses and seventy-eight single vision lenses to wear. Group 1 consisted of myopic eyes S–2.00D and below, Group 2 consisted of myopic eyes between S-2.25D and S–4.00D, while Group 3 consisted of myopic eyes S–4.25D and above. We attempted to learn the inhibitive effects against myopia progression attained by condition changes in refractive correction value at twelve months and under, thirteen to twenty-four months and twenty-five to thirty-six months, and to verify the statistical significance of the results thus pursued.
Results : By degree of myopia and at thirty-six months, Group 1 users of the reverse geometry lens showed an increase in visual acuity of S-0.11±0.32D (P>0.05), but this was not statistically significant while users of the MC lens and single vision lens in the same group had statistically significant (P<0.05) increases in visual acuity of S-1.06±0.68D (P<0.05) and S-1.95±1.07D, respectively. At thirty-six months in Group 2, users of the reverse geometric lens had an increase in visual acuity of S-0.45±0.78D, but this was statistically insignificant (P>0.05) while users of the MC and single vision lenses showed statistically significant (P<0.05) increases of S-1.06±0.68D (P<0.05) and S-1.95±1.07D, respectively. At thirty-six months in Group 3, wearers of the reverse geometric lens had a statistically insignificant (P>0.05) change of S-0.15±0.39D, while wearers of the MC lens and single vision lens had statistically significant (P<0.05) changes of S-1.02±0.42D and S-1.77±0.74D, respectively.
Conclusion : Regarding condition changes in refractive correction value by degree of myopia, from advanced to early in stage, wearers of the reverse geometry lens had low increases in change, a sign myopia progression was inhibited, and the MC lens was less effective than the reverse geometric lens while more effective than the single vision lens in inhibiting the progression of myopia, and it was discovered to have the greatest effect of inhibiting the progression of myopia in myopic eyes of S–2.00D and below.
