| 摘 要： | 目的：研究近视眼角膜的非球面特性和屈光状态之间的相关性,调查Q值（非球面性参数）与角膜曲率、前房深度、晶体厚度、玻璃体腔深度和眼轴长等参数的相关性。方法：随机选取113只正视眼和近视性屈光不正眼,检影验光法测量屈光度数,应用角膜地形图仪测量角膜前表面平均Q值及角膜曲率,应用眼部A超仪测量前房深度、晶体厚度、玻璃体腔深度和眼轴长度,SPSS10.0统计分析软件分别进行Q值对等效球镜度、角膜曲率等屈光参数的相关性分析。结果：角膜Q值和等效球镜度之间存在正相关（r=0.275,p〈0.01）,Q值和玻璃体深度,Q值和眼轴长之间存在明显相关（r=0.17,p〈0.01;r=0.23,p〈0.01）,Q值和角膜曲率半径之间无显著相关。近视程度越高,中央角膜曲率越小,前房和玻璃体腔深度越大,眼轴越长。结论：近视眼屈光度数越高,角膜前表面的Q值趋于正值,周边角膜变扁平的趋势越缓慢,而这种角膜非球面特性的变化与玻璃体腔深度和眼轴长度的增加有关。
