We show that by using the Fractional Beer-Lambert Law (FBLL)instead of the Beer-Lambert Law (BLL) as the governing equation of the optical problem, theformulation of the laser heat source changes, along with consequently, the distribution of temperatures.Our theoretical findings apply to laser thermal keratoplasty (LTK), used to reduce diopters ofhyperopia. We show that the FBLL o ers a new approach for heat conduction modeling of laserheating, which is more flexible and could better fit the data in cases where the BLL approach does notfit the data well. Our results can be extended to laser heating of other biological tissues and in othergeneral applications. Our findings imply a new insight to improve the accuracy of thermal models,since they involve a new formulation of the external heat source rather than the heat equation itself.
