摘要
选取6~11岁的23例首次在眼科医院验配平光高非球面微透镜(highly aspherical lenslets,HAL)设计离焦镜的正视眼儿童,观察其戴镜前和6个月后的眼轴(axial length,AL)和等效球镜度(spherical equivalent refraction,SER)的变化情况,观察平光离焦镜对正视眼儿童近视防控的临床效果。结果显示,戴镜6个月后,SER变化量从(-0.35±0.51)D变为(-0.02±0.30)D,SER变化速度有统计学差异(P=0.02);AL变化量从(0.37±0.26)mm变为(0.06±0.15)mm,AL变化速度有显著统计学差异(P<0.001)。说明配戴平光HAL离焦镜对正视眼儿童预防近视的发生有积极的作用。
Twenty-three children aged 6-11 years with emmetropia,who were fitted with plano highly aspherical lenslets(HAL)defocus lenses for the first time in an ophthalmic hospital,were selected.The changes in axial length(AL)and spherical equivalent refraction(SER)before and after wearing the lenses for 6 months were observed to analyze the clinical effects on prevention and control of myopia.The results showed that after wearing the lenses for 6 months,the amount of change in SER changed from(-0.35±0.51)D to(-0.02±0.30)D,with a statistically significant difference in the rate of change in SER(P=0.02).The amount of change in AL changed from(0.37±0.26)mm to(0.06±0.15)mm,with a highly statistically significant difference in the rate of change in AL(P<0.001).It was demonstrated that wearing plano HAL defocus lenses had a positive effect on preventing the occurrence of myopia in children with emmetropia.
