Novel Technique of Transepithelial Corneal Cross-Linking Using Iontophoresis in Progressive Keratoconus

(a) Slit-lamp photographs of a representative case (A1200) after T-ionto CL. One day after treatment, moderate epithelial haze of the central cornea (arrow), with no fluorescein staining, was noted in 5 cases (23%); this superficial haze regressed in all cases within 1 week after treatment. Six months after T-ionto CL, the cornea was clear in all cases. (b) Slit-lamp photographs of a representative case (B700) after standard CL. Six months after treatment, anterior corneal haze and mild stromal edema, which was confined to the posterior stroma, were still observed in 50% and 8% of controls, respectively.
