Effect of Ultraviolet Light Irradiation Combined with Riboflavin on Different Bacterial Pathogens from Ocular Surface Infection

Table 2

Survival fraction of Staphylococcus epidermis and Staphylococcus aureus under different UV irradiation time in the UV-riboflavin group (UV light energy: 5.273 mW/cm²).

Irradiation time (min)	Survival fraction of S. epidermidis (%)	Survival fraction of S. aureus (%)
0	100	100
5	47.5 ± 3.3	60.8 ± 4.3
10	43.5 ± 2.6	53.3 ± 3.0
20	38.1 ± 1.9	43.3 ± 1.7
30	6.2 ± 0.7	25.4 ± 1.4
