Influence of duration from first symptoms to correct diagnosis on clinical findings and need for pKP. A significant correlation of the appearance of strong pain ((A) p < 0.001), epithelial defect ((B) p = 0.017), and ring infiltrate ((D) p = 0.038) with a longer duration from first symptoms to correct diagnosis was shown. There was no significant correlation between duration to diagnosis and perineural infiltrates as well as pseudodendrites (not shown). (F) Furthermore, the number of pKPs performed significantly correlated with a longer duration from first symptoms to correct diagnosis (p = 0.0001)
