摘　　要：目的:探讨中低度近视前弹力层下激光角膜磨镶术(sub-Bowmans keratomileusis,SBK)及准分子激光原位角膜磨镶术(laser in situkeratomi leusis,LASIK)术后角膜后表面高度的变化。方法:中低度近视患者108例216眼,前瞻性、随机性为其1眼行SBK手术,其对侧眼行LASIK手术,术前及术后1wk;1,3,6mo应用Pentacam三维眼前节分析系统检查,分析比较SBK和LASIK两组间各个不同时间点的角膜后表面高度。结果:术后所有患者视力均达到或超过术前矫正视力。经配对t检验,SBK组和LASIK组术前术后,术后各时间段的比较,差异均无统计学意义。各时期两组间角膜后表面高度值比较,差异亦无统计学差异。结论:SBK和LASIK手术对中低度近视患者术后角膜后表面高度无明显影响。AIM：To evaluate and compare the influence of laser in situ keratomileusis（LASIK） and sub-Bowmans keratomileusis（SBK） on the elevation of posterior corneal surface in moderate to mild myopia. METHODS： Totally 108 patients with mild to moderate myopia were included. One eye in each patient was randomly selected to have LASIK（Group LASIK,n=108）, and SBK was performed in the follow eye（Group SBK,n=108）. Changes in the elevation of posterior corneal surface were measured with Pentacam system （Pentacam, OCULUS） preoperatively and 1 week,1,3,and 6 months postoperatively. RESULTS：After surgery, the acuity of vision in all eyes reached or exceeded that of preoperative. The posterior corneal surface in Group SBK displayed a mean elevation of 7.08±4.10μm, 6.54±4.27μm,6.48±3.41μm,6.63±311μm and 6.59±3.23μm,in preoperative,1 week,1 month, 3 months and 6 months postoperatively,respectively. In Group LASIK were 7.29±3.83μm,7.07±3.92μm,704±4.13μm,7.15±2.80μm,7.09±3.01μm respectively. None of the elevation of posterior corneal surface of Group LASIK or SBK was found to have a significant change after surgery. CONCLUSION： LASIK and SBK dont affect the elevation of posterior corneal surface significantly.
