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

Figure 4

Tangential corneal topography maps in a patient who underwent transepithelial corneal cross-linking in the right eye (A1500) and standard cross-linking in the left eye (B700). The preoperative, 1-week, and 1-, 3-, and 6-month postoperative maps are shown from the left to right, respectively. At 6 months, the flattening of was 1.74 D (from 59.46 D to 57.72 D) and 0.92 D (from 50.55 D to 49.63 D) in the right and left eye, respectively. Scale bars are normalized and shown in diopters. RE: right eye; LE: left eye; and represent the simulated keratometry values.
