Evaluation of Intrastromal Riboflavin Concentration in Human Corneas after Three Corneal Cross-Linking Imbibition Procedures: A Pilot Study

Table 1

Tested groups. Both EpiOff groups had a 15-minute imbibition with Ricrolin (standard) or RICROLIN+. The EpiOn group had a 30-minute imbibition and the Iontophoresis group had a 5-minute imbibition with RICROLIN+.
