1、中低度近视SBK与LASIK术后角膜后表面高度的临床研究雷玉琳1，郑秀云1，苏燕1，刘素美1，党光福2【摘要】目的：探讨中低度近视前弹力层下激光角膜磨镶术(sub?Boanskeratomileusis，SBK)及准分子激光原位角膜磨镶术(laserinsitukeratomileusis，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1o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
2、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。【关键词】SBK;LASIK;近视;Pentacam;角膜后表面 ElevationofposteriorcornealsurfaceafterSBKandLASIKinmoderatetomildmyopia Yu?LinLei1,Xiu?YunZheng1,YanSu1,Su?MeiLiu1,Gua
