Abstract Details


to evaluate the changes in central corneal thickness (CCT) and corneal volume (CV) in eyes that underwent corneal crosslinking (CCL)


National Ophtalmology Centre named after acad. Zarifa Aliyeva.


CCT and CV obtained with an Oculus Pentacam before, 1, 3 and 6 months after CCL were analyzed in 57 eyes of 52 patients with a mean preoperative refraction of -1.55 ± 2.33 D, and mean preoperative Sim?K of 46.98 ± 4.07 D, mean CCT of 491 ± 35 µm and mean CV of 56.72 ± 2.86 mm3 .


one month after CCL, we observed a statistically significant decrease (p<0.01) both in CCT (mean 449 ± 37 µm) and CV (mean 54.71 ± 3.15 mm3). Three months after CCL, we observed a further non significant decrease (p<0.6) in CCT (mean 448 ± 37 µm) and a significant decrease (p<0.01) in CV (mean 55.27 ± 3.07 mm3). Six months after CCL we observed a statistically significant increase (p<0.01) in CCT (mean 471 ± 46 µm) and a no significant increase (p<0.1) in CV (mean 56.03 ± 3.5 mm3).


even if our results have to be confirmed in further studies with larger population and longer follow up, our findings suggest that there is a corneal remodelling after CCL up to six months.
