Analysis of the control effect of DIMS on different degrees of myopia in adolescents
Objective To compare and observe the control effect of multi-point defocus incorporated multiple segments(DIMS)lens on different myopia degrees of adolescents of different ages.Methods A retrospective analysis was conducted on 110 adolescents with different myopia degrees,aged 6-18 years,admitted to Jilin Province People's Hospital from January 2020 to December 2022.They were divided into a low myopia group(spherical equivalent[SE]≤-0.50 D and>-3.00 D,n=56)and a moderate myopia group(SE≤-3.00 D and>-6.00 D,n=54)according to the SE of wearing DIMS.The changes of SE and axial length of adolescents in low myopia group and moderate myopia group aged 6 to 11 years and 12 to 18 years were observed respectively before and after wearing DIMS for 1 year.Results After one year's correction,in the low myopia group,the increase in SE in the age group of 6-11 years was greater than that in the age group of 12-18 years,and the difference was not statistically significant(P>0.05),and the growth rate of axial length was greater than that in the age of 12-18 years,and the difference was statistically significant(P<0.05).In the moderate myopia group,the increase in SE and axial length in the age group of 6-11 years old was greater than that in the age group of 12-18 years,and the difference was statistically significant(P<0.05).In the same age group,there was no significant difference between the low myopia group and the moderate myopia group in the growth range of SE and axial length(P>0.05).Conclusion DIMS can slow down the growth of axial length and refractive diopter for adolescents with different myopia degrees in different age groups,especially for those aged 12 to 18.DIMS can be used as an effective control method for adolescents with low and moderate myopia.
