Figure 1From: Evaluation of the cytotoxic effects of ophthalmic solutions containing benzalkonium chloride on corneal epithelium using an organotypic 3-D model Cytotoxicity of benzalkonium chloride (BAC) and saponin in 3-D corneal epithelial cultures. The viability of the 3-D corneal inserts was determined after treatment with BAC (A) or saponin (B) for 60 minutes at 37°C. Data represent mean percent (± range) of the saline control.Back to article page
