Fig. 1

Comparison of changes in preoperative and postoperative corneal elevation values between eyes that underwent combined transepithelial photorefractive keratectomy and accelerated corneal collagen cross-linking and transepithelial photorefractive keratectomy alone. PRK-CXL = Combined transepithelial photorefractive keratectomy and accelerated corneal collagen cross-linking; PRK = transepithelial photorefractive keratectomy; Δ = change; pph = measurements of 6-mm and 4-mm zone; central = measurements of 2-mm zone and center; max = measurements of maximal elevation zone; BFTE = best-fit toric ellipsoid; BFS = best-fit sphere. Error bars represent standard error of the mean (*p < 0.05, **p < 0.01)
