Modeling Laser Damage Thresholds Using the Thompson-Gerstman Model

Abstract

As lasers become more pervasive, the dangers posed by laser radiation to the human retina have increased. Computer aided modeling of laser tissue interaction in the retina allows for researchers to simulate parameter ranges where exposure can cause damage. While this approach has been studied using a variety of methods, one of the most referenced models has been the Thompson-Gerstman melanin granule model. Due to limited computing resources at the time, the original FORTRAN version of this model was implemented as a stand-alone serial code and was only able to model single-pulse exposures. A new C++ version of the Thompson-Gerstman model has been implemented, which expands both the functionality and portability of the method. The source type has been expanded to include multi-pulse as well as single pulse. Additionally, the functions developed by Thompson and Gerstman are now part of a library that can be accessed through other modeling software.
