(A) Right eye videokeratographic map in a 34-year-old female patient before treatment. The topographic pattern highlights irregular astigmatism (relative scale, tangential algorithm). (B) Pattern of transepithelial customized ablation. (C) Right eye videokeratographic map 2 years after customized photorefractive keratectomy and corneal collagen cross-linking with riboflavin and ultraviolet A irradiation. The topographic pattern showed an improvement in the corneal profile, with central flattening (relative scale, tangential algorithm).
