Fig. 1: Ocular discomfort and slit lamp observation after repeated CXL.

Line charts showed the NRS pain score (a), corneal fluorescein sodium staining score (b), and the conjunctival congestion score (c) before and after transepithelial re-crosslinking. Representative image showing the epithelial defect and recovery after re-crosslinking in one patient (d–g). On day 1 after re-crosslinking (e), both small plaque-like and punctual epithelial staining was seen within the central cornea (9 mm diameter).
