激光角膜屈光手术术后角膜生物力学特性会发生改变,评估这一改变需要综合多个生物力学的指标.准分子激光原位角膜磨镶术(LASIK)后角膜生物力学特性中的应力会明显降低,薄瓣有助于维护原有应力.表层切削在角膜生物力学稳定性优于LASIK.飞秒激光能完成平滑整齐的切面并进行边角设计,制作的角膜瓣与下方基质床间贴附更牢固,对角膜生物力学稳定性的干扰较小.重视并维护角膜生物力学可使角膜屈光手术更安全并且效果更稳定.

Corneal biomechanical properties will change after laser refractive surgery,which can be evaluated by several biomechanical parameters.The biomechanical stress will decrease remarkably after LASIK,but thin flap is helpful to maintain its stress.Excimer laser surface ablation has biomechanical advantages over LASIK procedure.The femtosecond laser technology can achieve smooth and regular incision and make the angle design.Flap adhesion is stronger when completed by a femtosecond laser.Laser refractive surgery will become safer and achieve more stable outcomes with the emphasis on biomechanical effects.
