1、郑州人学2009届顾!：学位论文中文摘要结论：1．LASIK、LASEK手术矫正近视，具有相似的临床效果。虽然LASIK术后裸眼视力恢复较LASEK快，但两者术后远期裸眼视力、残留屈光度无显著差异，证明两种术式对近视的矫正均有良好的稳定性。2．LASIK术后与LASEK术后角膜的修复方式有所不同，LASEK术后角膜的修复时间较LASIK长，但其克服了LASIK因角膜瓣所带来的并发症，两者各有优劣。3．LASIK、LASEK手术矫正近视，术后角膜地形图规整度相似，早期LASIK手术患者角膜地形图较LASEK手术患者角

2、膜地形图平整、规则，后期两者角膜地形图规整度无显著差异，证明两种术式对近视的矫正均有较好的安全性。4．LASEK术后角膜刺激症状，术后Haze及激素性高眼压与LASIK术后有明显差异。LASEK术后角膜刺激症状程度较LASIK重；LASEK较LASIK易产生激素性高眼压；LASIK术后无Haze的产生，LASEK术后不能完全避免Haze的发生。关键词：准分子激光原位角膜磨镶术(LASIK)；准分子激光角膜上皮瓣下磨镶术(LASEK)；近视；临床疗效IU郑州人学2009届硕l：学位论文英义摘要ClinicalOutc
