UV corneal cross-linking (CXL) is a crucial treatment in ophthalmic care which has the potential to be an alternative procedure in
reducing the progression of early keratoconus. This treatment needs further study to determine it is adequate to improve corneal
rigidity and visual rehabilitation. Therefore, descriptors of corneal asymmetry parameters should emphasize and refer to the clinical
assessment correctly to classify, monitor and evaluate the cross-linked cornea. There are many separate elements available in the
software to the Oculus Penatcam for assessing corneal asymmetry. These elements have been found to be more valuable in monitoring
the normalization of the cornea. According to previous studies, they have reported that the cornea becomes more optically regular
after CXL using the same indices, where, patients were analyzed after 1 year, after the treatment. However, their data did not assess the
posterior corneal elevation changes to show reliable improvement of corneal shape after cross-linking corneas. In this study, corneal
asymmetry indices were measured by Oculus Pentacam before and after CXL for keratoconus patient in conjunction with the back
elevation map. Assessing peripheral corneal asphericity (6-8 mm) might be more useful for increasing our comprehension of corneal
regularity after treatment, though more long-term follow-ups are need after CXL to confirm these findings.
