飞秒激光在白内障手术中的应用

Application of femtosecond laser-assisted cataract surgery

新近发展的飞秒激光技术以其穿透性强,精密度高等特点成功整合于白内障手术中。它利用激光爆破作用来制作透明角膜切口,精确进行晶状体前囊膜切开而代替手法撕囊,还可进行角膜缘松弛切开矫正散光等,因此其在白内障手术中具有广阔的应用前景。由于其出现时间较短,目前尚缺乏随机对照临床研究结果。在其实际应用中,手术适应证有待细化,应加快飞秒激光超声乳化一体机的研发进程。

Phacoemulsification is the main method for cataract surgery in the world. Femtosecond laser-assisted cataract surgery gives several surgical advantages over conventional phacoemulsification, including laser capsulotomy, lens fragmentation, clear cornea incisions and limbal relaxing incisions. The benefits such as reduced complication rates and improved postoperative refractive results are being investigated. In practical application, the surgical indication have to be detailed, and speeding up the progress of developing femtosecond laser combine phacomulsification system for cataract surgery is still important.
