Aim:
To analyse factors that correlate with best corrected visual acuity (BCVA) improvement after Intacs and trans-epithelial corneal collagen crosslinking with riboflavin-carboxymethylcellulose.
Methods:
A 3-year retrospective study of 14 eyes that underwent trans-epithelial crosslinking and same day Intacs.
Results:
The mean preoperative BCVA and spherical equivalent were significantly related to BCVA postoperatively.
Conclusion:
Poorer preoperative BCVA and spherical equivalent were associated with greater improvement in postoperative BCVA.
