Key result
Ocular pulse elastography quantified corneal strains generated by IOP pulsation and detected a significant decrease in corneal strain after UVA-riboflavin-induced corneal crosslinking.
Why the study?
In vivo evaluation of corneal biomechanics holds potential for improving ocular disease management, prompting the development of ocular pulse elastography to quantify corneal strains from IOP pulsations using high-frequency ultrasound.
Population
Whole porcine and human donor globes

May enable noninvasive corneal strain monitoring post-crosslinking; hypothesis-generating, with clinical utility unproven.
Ocular pulse elastography is a feasible ex vivo method to quantify corneal strains generated by IOP pulsation and detect biomechanical changes from corneal crosslinking.
Clayson et al. (2020) studied Corneal biomechanics. UVA-riboflavin-induced corneal crosslinking vs. Before crosslinking was evaluated on Corneal strains. Ocular pulse elastography quantified corneal strains generated by IOP pulsation and detected a significant decrease in corneal strain after UVA-riboflavin-induced corneal crosslinking.
