利用模型眼研究飞秒激光在屈光手术中的光学副作用。我们表明，彩虹眩光是主要的扰动，这可以避免随机分布的激光光斑内的透镜。对于角膜应用，如fs-LASIK，即使是点到点距离约为3 µm的规则网格也足以最大限度地减少彩虹眩光感知。当用大的3D图案处理透镜时，对比灵敏度受到影响。
Optical side-effects of fs-laser treatment in refractive surgery are investigated by means of a model eye. We show that rainbow glare is the predominant perturbation, which can be avoided by randomly distributing laser spots within the lens. For corneal applications such as fs-LASIK, even a regular grid with spot-to-spot distances of ~3 µm is sufficient to minimize rainbow glare perception. Contrast sensitivity is affected, when the lens is treated with large 3D-patterns.
