Figure 6. Effects of the active components of the four anti-inflammatory eye drops on cultured HCECs. HCECs were treated with 0.010%, 0.020%, 0.050%, and 0.100% solutions for 24 h (n=4) and analyzed by MTT assay (A) and LDH assay (B). Only diclofenac and bromfenac components showed significant cytotoxicity at the concentrations above 0.020% and 0.100%.
