Images of different grades of ocular surface features. (a) Mild corneal haze (F1): The opacity was smaller than 1/4 of the cornea, and iris details could be seen through it. (b) Moderate corneal haze (F2): The opacity was larger than 1/4 of the cornea with the lens and iris details blocked. (c) Severe corneal haze (F3): The lens and iris were completely hidden behind the opacity. (d) Nonvascularized (V0): Opacified cornea with no sign of vascularization. (e) Mildly vascularized (V1): Straight loop-shaped fine vessels grew on the corneal limbus from 4 to 12 o’clock. (f) Moderately vascularized (V2): Two large arborizing vessels grew across the limbus at 2 and 5 o’clock. (g) Severely vascularized (V3): The opacity was completely covered by retiform vessels
