Abstract

SUMMARY

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

Material and methods
CCT and CV obtained with the WaveLight® Oculyzer™ II (ALCON) 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 of491± 35 pm and mean CV of 56.72 ± 2.86 mm3.

Results
One month after CCL we observed a statistically significant decrease (p<0.01) both in CCT (mean 449 ± 37
pm) 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 pm) 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 pm) and no
significant increase (p<0.1) in CV (mean 56.03 ± 3.5 mm3).

Conclusion
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.
So, the study of topographic parameters such as the central thickness and volume of the cornea in patients with
keratoconus before and after surgery are the main indicators.
