Variation in the Best Fit Sphere Radius of Curvature as a Test to Detect Keratoconus Progression on a Scheimpflug-Based Corneal Tomographer

The introduction of corneal cross-linking (CXL) in 2003 revolutionized the treatment of corneal ectatic diseases such as keratoconus. The activation of riboflavin by ultraviolet-A 370-nm radiation creates an excited molecule that promotes new molecular bonds within and/or between collagen fibers. These new bonds stiffen the corneal stroma and halt keratectasia progression.1,2 The indication for cross-linking is typically clinical progression of the underlying disease. In addition to visual acuity and subjective refraction, topographic and tomographic indices are used to diagnose and monitor
