[摘要] 目的: 通过对角膜表面曲率、表面规则指数、表面不对称指数、中央角膜厚度的观察，评价眼挫伤后角膜表面形态的变化。方法: 单眼角膜挫伤患者25例，以健眼作对照眼，用TM S23角膜地形图检查仪测量健眼、患眼(1 d、1周、1月)3次，取结果最好者，记录角膜表面曲率、表面规则指数、表面不对称指数、中央角膜厚度。结果: 角膜表面曲率、表面规则指数、表面不对称指数、中央角膜厚度，与健眼比较，伤后1 d、1周均增加，经统计学分析，有显著性差异，1月后差异不明显，统计学分析无显著性。结论: 眼挫伤后角膜前表面曲率及表面不对称性增加，1周后呈下降趋势，1月后逐渐恢复到健眼水平。

[Abstract] Objective: To evaluate the change of the corneal surface morphology after ocular contusion through the observation of curvature, regularity index, and asymmetry index of corneal surface, as well as central corneal thickness. Methods: Twenty-five patients with monocular corneal trauma were selected, and healthy eyes were as the control.TM S23 corneal topography map was used to measure the healthy eye, bad eyes for 3 times (at the end of 1 day, 1 week, and 1 month, respectively) to get the best results. Corneal surface curvature, asymmetry index and central corneal thickness were recorded. Results: The corneal surface curvature, regularity index, asymmetry index, and the central corneal thickness were all increased compared with the healthy eyes 1 day or 1 week after injury, the differences were significantly different by statistics analysis, but there were no statistical differences between injured eyes and healthy eyes 1 month after injury. Conclusion: Corneal surface curvature and asymmetry increase after eye contusion within 1 week, but they decrease after 1 week, and gradually return to the healthy level post 1 month.
