摘　　要：【目的】探讨准分子激光原位角膜磨镶（LASIK）术后眼压的变化。【方法】采用非接触式眼压计对72例（139只眼）测量LAsIK术前后眼压；应用计算机辅助的角膜地形图分析系统对LAsIK术前后角膜地形图形态进行检测，并比较分析其与眼压的关系。【结果】术前平均眼压为（17．99±2．69）mmHg，术后1个月平均眼压为（10．99±2．70）mmHg，术后3个月平均眼压为（11．55±2．29）mmHg，明显低于术前，差异有显著性（P〈0．05）。术前后角膜形态对眼压无影响，术后偏心距离与术后眼压呈正相关。【结论】LASIK术后眼压测量值明显低于术前，且术后偏心距离与术后眼压呈正相关。[Objective] To evaluate the ehange of intraoeular pressure （IOP） readings after eximer laser in situ keratomileusis （LASIK）. [Methods] The lOP readings of 139 eyes were measured with noncontaet tonorneter （NCT） before and at one month, three months after LASIK. Computer-assisted corneal topography analysis system was used to measure corneal topographic pattern on 139 eyes before and after LASIK. The. relationship between these indicators was analyzed. [Results] Average IOP was 17.99±2.69 mmHg before operation, 10. 99±2.70mmHg at one month after the operation and 11.55±2. 29mmHg at three months after the operation. The lOP readings after LASIK were lower than those before LASIK （ t = 27.598, P 〈0. 001）. Corneal topographic shapes before and after LASIK had no association with IOP. But the longer was the distance of decentration, the higher was the IOP readings. [Conclusion] The iOP readings after LASIK are lower than those before LASIK. The IOP readings after LASIK are increased with the distance of deeentration.
