ABSTRACT = {Pan Retinal photocoagulation (PRP), a retinal laser surgical process, is simulated using a three-dimensional bio-heat transfer numerical model. Spots
of two different type of array, square array of 3 × 3 spots and a circular array of six spots surrounding a central spot, are sequentially irradiated.
Pennes bio-heat transfer model is used as the governing equation. Finite volume method is applied to find the temperature distribution due to laser
irradiation inside the human eye. Each spot is heated for 100 ms and subsequently cooled for 100 ms with an initial laser power of 0.2 W. Based on
the outcome of temperature distribution, the laser is pulsated in subsequent simulations to reduce the average peak temperature of spots to minimize
the temperature induced cell damage. A method to reduce the laser power to attain the peak temperature towards photocoagulation temperature
(60 ℃) is also presented.},
