A mathematical model of the human eye based on the bioheat transfer equation is developed. The intraocular temperature distribution is calculated using the Galerkin finite element method. A difficulty associated with the development of an accurate model of the human eye is the lack of reliable biological data available on the constants and parameters that are used in the model. These parameters include the thermal conductivities of the ocular tissues, the heat loss from the anterior corneal surface to the surroundings by convection and evaporation, and the convective heat loss from the sclera to the body core. The different values for the parameters reported in the ophthalmic literature are employed in the model, and the sensitivity of the temperature distribution to uncertainties in the parameters is investigated. A set of control parameter values is suggested for the normal human eye. The effect of the ambient temperature and the body-core temperature on the temperature distribution in the human eye is considered.
基于生物热传递方程建立了人眼的数学模型。采用伽辽金有限元法计算眼内温度分布。建立准确的人眼模型所面临的一个困难是，模型中使用的常数和参数缺乏可靠的生物学数据。这些参数包括眼组织的热导率、前角膜表面通过对流和蒸发向周围环境的热损失，以及巩膜向身体核心的对流热损失。模型采用了眼科文献中报道的不同参数值，并研究了温度分布对参数不确定性的敏感性。针对正常人眼提出了一组控制参数值。考虑了环境温度和身体核心温度对人眼温度分布的影响。
