飞秒激光在晶状体手术中应用的研究进展

飞秒激光主要用于角膜屈光手术，近年来随着全飞秒激光技术的问世，角膜屈光手术发生了巨大的变革和发展。飞秒激光的光致分解作用可使人体组织发生电离，可在组织内进行精确切削，而对切削区以外的组织影响较小，具有极高的安全性。飞秒激光在白内障手术中的应用包括透明角膜切口的操作、晶状体前囊膜的切开、晶状体核的碎核等，在晶状体屈光手术方面主要用于老视眼的矫治。就近年来飞秒激光技术在白内障手术和晶状体屈光手术中的应用进行综述。

Application of femtosecond laser in lens surgery

Femtosecond laser is mainly used in corneal refractive surgery. In recent years, the progress of the entire process of femtosecond laser makes a dramatic change and development of corneal refractive surgery. Photo- induced decomposition of femtosecond laser can ionize human tissue and accurately carry out intratissue cutting with less influence for the outside area of target site. So it is proved to have a high safety in clinical application. Femtosecond laser-assisted cataract surgery and lens refractive surgery is going to be a new stage in ophthalmology, and its application in cataract extraction includes the cutting of clear corneal incision and anterior capsula of lens as well as cutting up of lens nuclei. The advancement of femtosecond laser in lens refractive surgery mainly is the correction of presbyopia. The progress of femtosecond laser in lens surgery was summarized.
