摘要
角膜屈光手术引入飞秒激光制作角膜瓣已经有十年的历史，设备从原先的高脉冲能量低频率逐渐转变为当前的低脉冲能量高频率。与传统的机械式显微角膜板层切开刀相比，飞秒激光具有一定的优势，如制做准分子激光原位角膜磨镶术（LASIK）角膜瓣厚度精确、均匀，术中无角膜瓣破碎等严重并发症；可以个性化地设计角膜瓣形状、大小以及边切角度。也有利用飞秒激光进行角膜透镜切除，即全飞秒激光矫正近视及散光的方法。但飞秒激光也有其特殊的术中及术后并发症，如激光制瓣过程中负压丢失、纽扣瓣、不透明气泡层、彩虹症及光敏综合征等。我们对此要有正确客观的认识，随着设备技术的改进与操作经验的积累．不断提高角膜屈光手术的疗效以及患者的满意度。
Since 2002, femtosecond lasers have been used for more than a decade to create laser in situ keratomileusis （LASIK） flaps. The equipment shifted from higher pulse energy and lower frequency to lower pulse energy and higher frequency. Compared to the traditional mechanical microkeratome, the femtosecond laser has its own advantages, such as a more precise and even corneal flap, no severe flap break during the operation, and the flap can be customized for shape, size and side cutting angle. The femtosecond laser can also perform corneal lenticule extraction for correcting myopia and astigmatism. Nevertheless, complications such as suction loss during the operation, an opaque bubble layer, a flap button hole and some visual problems after femtosecond laser-assisted LASIK should be of concern.
