Effect of surfactant, BAK, and PBS-lens exposure on the metabolic activity of corneal epithelial cells in a curved, stratified culture.

Following exposure to the stimuli for 24 hours, the stratified culture was digested and the cells were routinely processed for ADP/ATP expression using a luciferase assay. All values are expressed as a ratio relative to the ADP/ATP ratio on cells incubated with no lens or solution (no lens control).n = 4.*significantly different from BA PBS control, p
