A sample population of myopes with an initial correction of 2 DS or more is extracted from the longitudinal sample of ametropes reported by Saunders (1986). The myopes are partitioned by means of cluster analysis and, as a result, three distinct groups of myopes are identified. The time/regression equations which best describe the groups are stated. It is concluded that meaningful long-term prognosis of medium and high myopes is unlikely and that reasonable prediction of short-term trends requires at least two consecutive refraction data to determine the group allocation of a myope.
从桑德斯（1986年）报告的屈光不正患者纵向样本中提取初始矫正度为2屈光度或更高的近视样本群体。通过聚类分析对近视患者进行划分，结果确定了三组不同的近视群体。阐述了最能描述这些群体的时间/回归方程。得出的结论是，中高度近视不太可能有有意义的长期预后，并且对短期趋势的合理预测至少需要两个连续的验光数据来确定近视患者的组分配。
