Abstract
We suggest a general method to determine the optimum laser parameters for maximizing the ablation efficiency for different materials (in particular human cornea) at different incidence angles. The model is comprehensive and incorporates laser beam characteristics and ablative spot properties. The model further provides a method to convert energy fluctuations during ablation to equivalent ablation deviations in the cornea. The proposed model can be used for calibration, verification and validation purposes of laser systems used for ablation processes at relatively low cost and would directly improve the quality of results.
摘要
我们提出了一种通用方法，用于确定在不同入射角下使不同材料（特别是人角膜）的消融效率最大化的最佳激光参数。该模型全面且包含了激光束特性和消融光斑特性。该模型还提供了一种方法，可将消融过程中的能量波动转换为角膜中的等效消融偏差。所提出的模型可用于以相对较低的成本对用于消融过程的激光系统进行校准、验证和确认，并且将直接提高结果的质量。
