A novel approach for applanation-free femtosecond refractive surgery with the help of a contact liquid layer is presented. A laboratory device for performing corneal procedures is described based on a femtosecond-laser system which has been tested and evaluated by processing ex vivo pig eyes. With its help, flap cuttings for different flap thicknesses were performed. The accomplished corneal surfaces are comparable to already published results. The reproducibility of the flap thicknesses is very good, with a standard deviation of 10 µm. The processing and removal of an intrastromal lenticule as thin as 30 µm could be shown. The extraction of such lenticule through a corneal side channel could also be accomplished successfully and is a promising improvement of the overall surgery procedure.
本文介绍了一种借助接触液层进行免压平飞秒屈光手术的新方法。描述了一种基于飞秒激光系统的用于角膜手术的实验室设备，该设备已通过对离体猪眼进行处理进行了测试和评估。借助该设备，制作了不同瓣厚度的瓣切口。完成的角膜表面与已发表的结果相当。瓣厚度的再现性非常好，标准偏差为10 µm。可以展示处理和移除薄至30 µm的基质内透镜。通过角膜侧通道成功提取这种透镜也是整个手术过程的一个有前景的改进。
