ABSTRACT: In this paper, a bio-heat transfer model of temperature
distribution in human eye is discussed using appropriate boundary conditions
for cornea and sclera. Variational finite element method with Crank-Nicolson
scheme is used to calculate the transient temperature distribution in normal
human eye. The temperature with and without the effect of blood perfusion and metabolism
on retina is simulated and compared for various ambient temperatures,
evaporation rates and lens thermal conductivities. The obtained results
are compared with experimental results and past results found
in literatures. The results show that the steady state corneal temperature is
achieved in around 31 and 45 minute of exposure at ambient
temperatures 10℃ and 50℃ respectively. Steady state eye temperature is achieved earlier
at higher evaporation rate. Similar result is achieved for
higher lens thermal conductivity and also for lower ambient
temperature.
