摘　　要：随着准分子激光屈光手术技术的成熟和手术设备的更新，手术的并发症逐渐减少。准分子激光角膜原位磨镶术（LASIK）和准分子激光上皮下角膜磨镶术（LASEK）术后中央角膜变薄，在角膜强度相对降低和正常眼压的作用下，可造成不同程度的角膜前凸。由于角膜后表面不直接受准分子激光手术本身和愈合过程的影响，所以一般用角膜后表面参数的改变来评价角膜的前凸程度。近年来随着眼前节分析系统等仪器的应用，角膜后表面的形态得以更加深入地了解。就准分子激光屈光手术后角膜后表面前凸的表现、原理、预防措施等进行综述。With the mature of techniques and development of equipments in excimer laser corneal refractive surgery, the postoperative complications are decreasing gradually. As the center of cornea become thin after laser in situ keratomileusis （LASIK） and laser subepithelial keratomileusis （LASEK） , the strength of cornea and the intraocular pressure relatively step down, which can cause cornea anterior protrusion more or less. Because the posterior surface which is not directly affected by surgical process and healing process, so it is usually used to evaluate the protrusion of cornea. As the application of ophthalmic anterior segment imaging and analysis system, we can get more message of cornea posterior surface. The manifestation, principle and precautionary measures of corneal posterior surface anterior protrusion after the exeimer laser corneal refractive surgery were reviewed.
