e2speqod1 represent SE at baseline;kod represent corneal power;CP represent lens power;aldf31d represent the difference in axial length between baseline and 6-year follow-upcages represent age groups.<br>

e2speqod1 代表基线时的球镜度数（Spherical Equivalent，SE）；kod 代表角膜屈光力（corneal power）；CP 代表晶状体屈光力（lens power）；aldf31d 代表基线与6年随访时的眼轴长度（axial length）差值；cages 代表年龄组（age groups）。
