Figure 4. Effects of the four anti-inflammatory eye drops on the viability of cultured HCECs. HCECs were treated with 0.001% eye drops for 24 h (n=4). The cells were stained with 7-AAD, and cell mortality was analyzed using flow cytometry. All four eye drops showed significant effects on the viability of HCECs, and Diclofenac Sodium Eye Drops showed the most significant toxicity among the four eye drops.
