Changes in corneal refraction and topography among 145 myopic children were monitored over a three-year period as part of a clinical trial of myopia treatment. The spherical equivalent of the right eye increased from -1.46 D to -3.13 D. Refractive astigmatism increased from 0.28 D to 0.46. Corneal astigmatism, horizontal and vertical corneal curvatures, as well as shape factors, did not change significantly. The mean deviation of the corneal apex from the visual axis increased from 0.48 mm to 0.67 mm. Girls showed steeper corneal curvatures than boys. For both sexes the vertical corneal curvatures were steeper, and shape factors were smaller than those along the horizontal plane. Axial elongation of the eye was the primary explanation for myopic progression.
作为一项近视治疗临床试验的一部分，对145名近视儿童的角膜屈光和地形图变化进行了为期三年的监测。右眼等效球镜度从-1.46 D增加到-3.13 D。屈光性散光从0.28 D增加到0.46。角膜散光、角膜水平和垂直曲率以及形态因子均无显著变化。角膜顶点与视轴的平均偏差从0.48 mm增加到0.67 mm。女孩的角膜曲率比男孩更陡。对于男女两性，垂直角膜曲率更陡，形态因子比水平面上的更小。眼轴延长是近视进展的主要原因。
