全部病例球镜的主要变化为远视度数减少或近视度数增加（75％）。

During development there was decrease in the degree of hypermetropia of increase in the degree of myopia (75% ) on the major spherical changes of all cases.

与角膜厚度、眼压无明显的相关性。结论眼轴长度、角膜屈光力、晶状体厚度、前房深度和年龄对近视度数(等值球镜度数)均有一定的影响。

Conclusion the length of axis, corneal refractive power, lens thickness, anterior chamber depth and age have certain effect on the spherical equivalent refraction.

方法在正常眼前放置正、负球镜，人工诱导单纯性远视、近视性屈光参差。

Methods Hypermetropia and myopia were induced by playing concave and convex lens in front of eyes of 32 subjects.
