Cytopathic effects of PHMB on human corneal epithelial cells. Human corneal epithelial (HCE) cells were incubated with 0.02% PHMB for 10 min to 5 h. PHMB showed 46% lysis of the HCE cells within 10 min. After treatment of 0.02% PHMB for 2 h, over 60% of the HCE cells were lysed. The data are expressed as means ± SEM of the results of three independent experiments, run in triplicate.
