Abstract Details

Purpose:

To evaluate the effectiveness of using a specialized contact lens to protect the cornealendothelium during corneal collagen crosslinking in progressive keratoconus in thin corneas

Setting:

Rowad Cornea Center Giza Egypt

Methods:

17 eyes of 10 patients with progressive KC were included in the study with  thinnest point of less than 400 micron on Pentacam.   After epithelial removal, a special Contact Lens without a UV filter (Soflens, Bausch & Lomb) soaked in riboflavin was applied over the cornea and riboflavin was applied for 10 minutes followed by UV application  (9mW for 10 minutes) One month after surgery , AS OCT imaging was used to evaluate the presence and depth of a stromal demarcation line.

Results:

A visible demarcation line was detected by AS OCT  in all cases with a mean depth of 187 microns

Conclusions:

Contact lens assisted epithelium off accelerated CXL appears to be safe in thin corneas, however the demarcation line is shallower than standard epithelium off CXL.
