文摘为比较多区正向离焦镜片(传统多点离焦技术,defocus incorporated multiple segments,DIMS)与费马螺旋多点雾化镜片(微点阵多透镜集合技术,Micro Lens Panel,MLP)对儿童青少年近视的防控效果,本文选取8~12岁近视儿童青少年60例共120眼,均为连续配戴≥12个月的DIMS、MLP镜片者进行自身对照回顾性研究,并对眼轴长度、球镜及柱镜度数的变化进行了分析。结果显示,在控制眼轴年增长量(MLP:0.05~0.06mm vs DIMS:0.19~0.20mm)、保持球镜度数稳定年加深(MLP:0.10~0.12D vs DIMS:0.23~0.25D)、改善散光年加深(MLP:-0.03~-0.05D vs DIMS:0.10~0.11D)方面,MLP镜片均显著优于DIMS镜片(P<0.0001),MLP镜片延缓近视加深有效率为82.06%,回退眼轴比例为41.67%。结论:MLP更适合于散光或者近视快速进展的孩子,DIMS为单纯缓慢进展的近视孩子提供基本防控,并且可作为个体化近视防控的基础。
