Ahram mineral water-induced sulfate keratopathy: histopathologic, electron microscopic, and confocal scan features.

Purpose: To characterize histopathologic, electron microscopic, and confocal scan features of Ahram mineral water (AMW)-induced keratopathy in cadaver corneas.

Methods: Seven cadaver globes were examined, 5 of which were exposed to AMW from the corneal side for different durations (30 seconds and 3, 15, 30, and 60 minutes) and the other 2 were considered as control. After performing confocal scan on each cornea, we excised the corneoscleral rim and sent it for histopathologic evaluation.
