Abstract

In order to model the thermal effect of laser exposure of the iris during laser corneal surgery, we simulated the temperature increase in porcine cadaver iris. The simulation data for the 60 kHz FS60 Laser showed that the temperature increased up to 1.23°C and 2.45°C (at laser pulse energy 1 and 2 [micro sign]J, respectively) by the 24 second procedure time. Calculated temperature profiles show good agreement with data obtained from ex vivo experiments using porcine cadaver iris. Simulation results of different types of femtosecond lasers indicate that the Laser in situ keratomileusis procedure does not present a safety hazard to the iris.

摘要

为了模拟激光角膜手术中虹膜激光照射的热效应，我们模拟了猪尸体虹膜的温度升高。60 kHz FS60 激光的模拟数据表明，在 24 秒的手术时间内，温度分别升高了 1.23°C 和 2.45°C（激光脉冲能量分别为 1 和 2 [微符号]J）。计算出的温度分布与使用猪尸体虹膜进行离体实验获得的数据吻合良好。不同类型的飞秒激光的模拟结果表明，准分子激光原位角膜磨镶术不会对虹膜造成安全隐患。
