Fig. 3From: Factors influencing haze formation and corneal flattening, and the impact of haze on visual acuity after conventional collagen cross-linking: a 12-month retrospective studyRelationship between changes in densitometry at 12 months (ΔcGSU-0-2A, GSU/mm3) and changes in maximum keratometry (ΔKmax, D). Higher decrease in Kmax (i.e. corneal flattening) is associated with greater increase of densitometryBack to article page
