摘要

摘要本文综述了飞秒激光在眼科中的历史发展和现代应用，重点介绍了其中涉及的光学概念。激光技术是独一无二的，因为它可以通过光学透明组织在眼睛内部进行非常精确的切割，而不需要任何机械开口。历史上，激光首先用于屈光性角膜手术，后来也用于治疗性角膜手术和晶状体手术。更多新的眼科应用领域正在开发中。最新的激光系统概念是低脉冲能量和高脉冲频率:通过使用更大的数值孔径聚焦光学器件，光学击穿所需的脉冲能量减少，并且具有最小副作用的非热组织切割成为可能。

Femtosecond lasers for eye surgery applications: historical overview and modern low pulse energy concepts

Abstract This review provides an overview of the historical development and modern applications of femtosecond (fs) lasers in ophthalmology, with a focus on the optical concepts involved. fs-Laser technology is unique because it allows very precise cutting inside the eye through optically transparent tissue, without a need for any mechanical openings. fs-Lasers were historically first used for refractive cornea surgery, later also for therapeutic cornea procedures and lens surgery. Further new areas of ophthalmic application are under development. The latest laser system concept is low pulse energy and high pulse frequency: by using larger numerical aperture focusing optics, the pulse energy required for optical breakdown decreases, and athermal tissue cutting with minimal side effects is enabled.
