Pentacam anterior curvature differential maps shows anterior curvature maps from the right eye (OD) in March 2023 and September 2022, respectively (a and c); anterior curvature maps from the left eye (OS) in March 2023 and September 2022, respectively (b and d). Note that there was no evident progression of the ectatic disease, even a mild keratometric reduction in OD (a–c) with clinical treatment with oral supplementation of vitamin B2 and a decrease in curvature in OS (b–d) with the intrastromal corneal ring segments
