Purpose : The purpose of this study was to utilize the basic data of regional refraction change by comparison of the refractive state of elementary school students in Wonju, Gangwon-do.

Methods : Uncorrected visual acuity was classified into 6 groups, according to age, such as 58 eyes of 8 years, 69 eyes of 9 years, 55 eyes of 10 years, 60 eyes of 11 years, 33 eyes of 12 years, and 23 eyes of 13 years. The spherical refractive power according to the degree of myopia was classified as mild myopia of less than ?2.00 D, moderation myopia of ?2.00 D ~ -5.00 D, and high myopia of ?5.00 D or higher. A total of 298 myopic eyes were performed refraction before and after cycloplegic refraction(CR).

Results : Uncorrected visual acuity of 101 eyes having 0.5~0.6 was shown the highest, spherical mean value was ?0.83¡¾0.25 D, the refraction range was ?0.25 D to ?1.50 D, and average age was 10.2 years. In comparison of spherical powers according to age, the manifest refraction(MR) value of children at 8 years was ?1.15¡¾0.64 D, CR value was ?0.92¡¾0.75 D, and myopia under CR was 0.24¡¾0.36 D lower(t=-4.745, p<0.050), and the MR value of children at 13 years was ?1.40¡¾1.36 D, CR value was ?1.26¡¾1.26 D, and myopia under CR was 0.21¡¾0.21 D lower (t=-2.614, p<0.050). As a result of comparing between MR and CR according to the degree of myopia, the MR and the CR values of mild myopia in 8 years children were ?1.02¡¾0.44 D and ?0.79¡¾0.62 D, respectively, and the myopia under CR was 0.24¡¾0.37 D lower(t=-4.473, p<0.050), and that in 13 years children were ?0.86¡¾0.51 D and ? 0.75¡¾0.51 D, respectively and the myopia under CR was 0.19¡¾0.20 D lower(t=-1.810, p<0.050)

Conclusion : There was statistically a significant difference in spherical power and mild myopia between 8 and 13 years children, when compared with the MR and the CR values of spherical power for elementary school students in Wonju, Gangwon-do. In addition, it was confirmed that the refractive power increases finely at all ages except for 9 years.
