Abstract

Purpose : The study looked at how effective each group wearing MyoVison lens, MC lens, and Single Vision lensdepending on their parents' myopia condition. Methods : The study observed the changeof spherical equivalent among customers, who visited between January 2010 and December 2016,of an optical shop in Incheon Metropolitan City. And we observed MyoVision 152 eyes, MC Lens 86 eyes and Single Vision lens 270 eyes. This study was conducted using SPSS ver18, which analyzes the changes in average values of MyoVision, MC Lens, and Single Vision for a year.In each group, the differences in the group were compared using the Paired T-test and then one-way ANOVA (post-hoc; Bonferroni) Results : Group-to-group comparisons showed that MyoVision and MC Lens have a shorterinhibition than Single Vision. In particular, MyoVisionand MC Lens showed different relief effects depending on the degree of refraction of parents.When both parents had normal refractive, the change between MyoVision and Single Vision lens was $-0.35{\pm}0.05D$. When the father had a refraction MC lens were $-0.36{\pm}0.14D$ more effective than Single Vision. When only the mother had refraction, the mean value between MyoVision and Single Vision lens was $-0.37{\pm}0.06D$, and the mean between MC lens and Single Vision lens was $-0.38{\pm}0.08D$. And when both parents had refraction problems, the mean value change between MyoVision and Single Vision lens was $-0.28{\pm}0.07D$, and $-0.31{\pm}0.07D$, respectively. Conclusion : MyoVision and MC Lens appeared to have no effect on the functions of mitigating myopia in within group comparisons, but MyoVision and MC Lens showed reducing myopia than Single Vision in between group.

목적 : 본 연구는 부모의 근시정도에 따라 MC lens, MyoVisonlens 그리고 Single Vision lens를 착용한 그룹들이 각각 어느 정도 효과를 보이는지를 알아보고자 하였다. 방법 : 연구대상은 인천광역시 소재의 한 안경원의 고객 중 2010년 1월에서 2016년 12월 사이에 방문한 7세에서 20세 사이 안질환이 없는 근시안 MyoVision 152안, MC lens 86안, Single Vision lens 270안을 대상으로 등가 구면도수의 변화를 관찰하였다. 본 연구 자료는 MyoVision, MC lens 그리고 Single Vision의 1년간 평균값 변화를 SPSS ver18을 이용하여 분석하였다.각 그룹별로 처음 방문했을 때와 1년 후 재방문 했을 때의 그룹 내 차이를 Paired T-test 이용하여 비교하였고, 이후 One-Way ANOVA(Post Hoc; Bonferroni)분석을 통해 사후분석을 진행하였다. 결과 : 그룹간 비교에서는 MyoVision과 MC lens가 Single Vision 보다 근시 완화효과가 있는 것으로 나타났다. 특히 부모의 굴절이상도에 따라 MyoVision과 MC lens의 근시 완화효과가 다르게 나타났다. 부모 모두 굴절 이상도가 정상일 때는 MyoVision 과 Single Vision lens 간의 변화는 $-0.35{\pm}0.05D$로 통계적으로 유의한 변화값이 나타났다. 아버지만 굴절이상이 있을 때는 MC lens는 Single Vision 보다 $-0.36{\pm}0.14D$만큼 더 효과적인 것으로 나타났다. 그리고 어머니만 굴절이상이 있을 때는 MyoVision 과 Single Vision lens 간의 평균값은 $-0.37{\pm}0.06D$의 변화를 보였고 MC lens 와 Single Vision lens 간의 평균값은 $-0.38{\pm}0.08D$가 변화하여 각각 Single Vision lens에 비해서 근시를 완화시켜주는 효과가 있는 것으로 나타났다.부모모두 굴절이상이 있을 때는 MyoVision 과 Single Vision lens 간의 평균값 변화와 MC lens 와 Single Vision lens 간의 평균값 변화는 각각 $-0.28{\pm}0.07D$, $-0.31{\pm}0.07D$로 MyoVision 과 MC렌즈 모두 통계적으로 유희한 변화값을 보여 근시진행에 억제 효과가 있는 것으로 나타났다. 결론 : 본 연구결과 각 그룹 내에서 MyoVision, MC lens 그리고 Single Vision모두 근시를 완화시켜주는 기능에 있어서 효과가 없는 것으로 보였으나 그룹 간 비교에서는 MyoVision과 MC lens가 Single Vision 보다 근시 완화효과가 있는 것으로 나타났다.
