Ex-Vivo Porcine Cornea Suprathreshold Dose Response to 10 ms and 100 ms Pulse Durations at 1940 nm

Abstract

Advances in the development and increased use of high-energy lasers in military settings requires the development of corneal dose response models that relate the level of exposure to the probability and severity of an injury. This enables a comprehensive risk assessment as part of pre-employment reviews. To develop and validate those models, there is a need to document and characterize supra-threshold corneal damage, including ablation, resulting from laser exposures. There is a lack of data on supra-threshold corneal exposures for wavelength between 1400 nm and 2000 nm. This study focused on documenting and characterizing suprathreshold corneal damage in response to a strongly absorbing laser at 1940 nm for 10 ms and 100 ms single pulse exposures in excised porcine corneas.
