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

Figure 5

((a), (b), and (c)) Graphs showing best spectacle corrected visual acuity (BSCVA, LogMAR), contrast sensitivity function (CSF, log units), and spherical equivalent refraction (D) compared with baseline at 3 days, 1 week, and 1, 3, and 6 months after T-ionto CL (black curve) and standard CL (grey curve), respectively. Bars indicate ± standard deviation. BSCVA improved significantly () and spherical equivalent refraction was significantly less myopic () after T-ionto CL. On average, visual performance decreased in the first week after standard CL and reached preoperative values at 3 months postoperatively.
