目的：应用Pentacam分析系统对准分子激光上皮下角膜磨镶术(LASEK)和准分子激光原位角膜磨镶术(LASIK)后角膜后表面高度的变化进行观察比较。
方法：回顾性分析我院2013-01/06行LASEK和LASIK术治疗的近视患者50例100眼的临床资料，比较术前和术后3mo时采用Pentacam分析系统测量的角膜后表面高度变化。
结果：术后3mo，LASEK角膜后表面高度为7.4±5.0mm，显著高于术前(5.6±3.4mm)。LASIK角膜后表面高度为7.5±5.1mm，显著高于术前(5.5±3.5mm)，差异均具有统计学意义(均P<0.05)； 术后3mo后，两种术式角膜表面高度前凸量(1.74±3.67mm vs 1.80±3.61mm)相当，差异无统计学意义(P>0.05)。
结论：LASEK和LASIK术后角膜后表面均前移，早期LASIK术角膜表面高度前移量高于LASEK术，但前移量均不足以引发不良反应。

AIM: To explore the application of Pentacam excimer laser epithelial keratomileusis(LASEK)and excimer laser
in situ keratomileusis(LASIK)after the changes of posterior corneal surface height.
METHODS: Retrospective analysis of clinical data of 100 patients with myopia by using LASEK and LASIK for the treatment of the 50 patients(100 eyes)in our hospital from January 2013 to June 2013, surface height changes after preoperative and postoperative 3 months were compared by measuring Pentacam corneal analysis system.
RESULTS: Three months after operation, the LASEK posterior corneal surface height was 7.4±5.0mm, significantly higher than 5.6±3.4mm before operation, LASIK posterior corneal surface height was 7.5±5.1mm, significantly higher than 5.5±3.5mm before operation, the differences were statistically significant(P<0.05); 6 months after surgery, two methods of corneal surface height obtained was 1.74±3.67mm and 1.80±3.61mm, there was no significant difference(P>0.05).
CONCLUSION: LASEK and LASIK on corneal posterior surface forward, LASIK is slightly obvious in early period.
