Figure 3. Effects of the four anti-inflammatory eye drops on cell damage of cultured HCECs. HCECs were treated with 0.001%, 0.002%, and 0.010% eye drops for 24 h (n=4). Cell supernatants were collected and detected by LDH assay. LDH release after exposure of cells to the eye drops was concentration dependent. Diclofenac Sodium Eye Drops showed the most significant toxicity among the four eye drops at the three concentration groups. At the higher 0.010% concentration, all four eye drops caused apparent cell damage and LDH releasing, and the differences among them became less significant.
