With the increase in laser technology for ophthalmic surgeries, the knowledge of the heat transfer mechanism in the human eye becomes increasingly important. The accuracy in predicting thermal behavior is linked to the use of adequate thermal and numerical methods. In this way, this study presents the results of two two-dimensional models, cartesian and axisymmetric in cylindrical coordinate, to calculate transient temperature of the human eye. Heat transfer was modeled using the Pennes’ thermal model, and the mechanism of heat conduction was assessed through two different approaches, classical Fourier law and non-Fourier law also known as Cattaneo and Vernotee modification. The Fourier and non-Fourier bio-heat equations were solved using the finite element method and the numerical solutions were compared to solutions reported in the literature, as well as numerical results were presented under various conditions to evaluate the differences between the two approaches to predict the diffusion of heat inside the retinal region of human eye subjected intentionally and accidentally to heat sources.

随着用于眼科手术的激光技术的增加，对人眼中的热传递机理的了解变得越来越重要。预测热行为的准确性与使用适当的热方法和数值方法有关。通过这种方式，本研究提出了圆柱坐标中的笛卡尔坐标系和轴对称二维二维模型的结果，以计算人眼的瞬态温度。使用Pennes的热模型对热传递进行建模，并通过两种不同的方法（经典的傅里叶定律和非傅里叶定律，也称为Cattaneo和Vernotee修正）来评估热传导机理。使用有限元方法求解了傅立叶和非傅立叶生物热方程，并将数值解与文献报道的解进行了比较，
