Abstract
We have developed a two-dimensional computer model to predict the temperature increase of the retina during femtosecond corneal laser flap cutting. Simulating a typical clinical setting for 150-kHz iFS advanced femtosecond laser (0.8- to 1-μJ laser pulse energy and 15-s procedure time at a laser wavelength of 1053 nm), the temperature increase is 0.2°C. Calculated temperature profiles show good agreement with data obtained from ex vivo experiments using human cadaver retina. Simulation results obtained for different commercial femtosecond lasers indicate that during the laser in situ keratomileusis procedure the temperature increase of the retina is insufficient to induce damage.
摘要
我们开发了一个二维计算机模型，以预测飞秒角膜激光瓣切割过程中视网膜的温升。模拟典型的 150kHz iFS 高级飞秒激光（0.8-1μJ 激光脉冲能量和 15s 的激光波长为 1053nm 的激光作用时间）的临床设置，温升为 0.2°C。计算出的温度分布与使用人尸体视网膜进行的离体实验数据吻合良好。对不同商业飞秒激光器的模拟结果表明，在激光原位角膜磨镶术中，视网膜的温升不足以引起损伤。
