An $ABCD$ beam-propagation method was used to build a first-order mathematical model of a thermal lens effect from a near-infrared laser beam in water and ocular media. The model was found to fit experimental z-scan data best when the thermo-optic coefficient $\mathrm{d}n∕\mathrm{d}T$ of liquid water at $292\mathrm{K}$ was $-4.46\times {10}^{-5}{\mathrm{K}}^{-1}$ . The physiological parameters of the human eye were simulated in a simple eye model using this fitted $\mathrm{d}n∕\mathrm{d}T$ value. Conservative model simulations for 1150 and $1318\mathrm{nm}$ laser radiation include parameter sets used in experimental ocular exposures performed by Zuclich et al. [Health Phys. 92, 15 (2007)] to illustrate the transient response of the thermal lens approaching the limits of the retinal damage thresholds for equivalent laser radiation sources.
