Jack Lund
SEG Member - PG Laser Guidelines

David Jack Lund retired in 2008 after a 46 year career as a research physicist with the US Army Medical Research Command where he studied the effect of laser radiation on ocular tissue and the visual system. His principle focus was in the conduct and analysis of research pertaining to the injurious effect to the retina of laser exposure and the determination of the minimum dose required to produce retinal injury. He has authored /coauthored papers relating the damaging effect of laser irradiation to the parameters of the laser exposure which are highly instructive to the formulation of the current ICNIRP, ANSI, and IEC guidance for calculation of the maximum permissible exposure of the human eye to laser radiation. His research has included studies of the hazards of “eye safe” infrared lasers, experimental studies of the additivity of effect for exposure to repetitive laser pulses yielding empirical methods for assessing the hazards of such exposures, experimental determination of action spectra for the threshold for laser-induced thermal retinal injury and studies of the dependence of the threshold for laser-induced retinal injury on both the duration of the laser exposure and the diameter of the laser-irradiated area on the retina. He serves on ANSI and CIE committees/subcommittees and collaborates with international investigators in the exploration of laser-induced ocular bioeffects. He was an ICNIRP Consulting Expert from 2002 to 2012. He was then elected to join the Scientific Expert Group in 2018.
