Autobahn of Cornea cross linking to treat Keratoconus


BMW on the autobahn is a hair rising experience. Now our German friends want to bring that concept to cxl or corneal cross linking. You may have heard of accelerated cornea cross linking? This is cxl with 10 minutes of UV radiation treatment, In the newest version they propose treatment of only 5 minutes utilizing 18 mw/cm2 of UV radiation.

This would of great benefit to patients. The amount of time they have to stare at the blue light would decrease. Exposure of the cornea to the elements  would be less.

We would like to quote the results of the study here ” The mean follow-up time was 21.7 ± 7.2 months (range, 12-34 months). No statistically significant changes were found in the mean corrected distance visual acuity, corneal astigmatism, Kmean, Kflat, Ksteep, corneal pachymetry (at the apex and at the thinnest point), and corneal densitometry at follow-up. A significant reduction of Kmax, index of surface variance, index of vertical asymmetry, and Km of the posterior corneal surface (Km(B)) was observed (Kmax: P = 0.018; index of surface variance: P = 0.016; index of vertical asymmetry: P = 0.038; Km(B): P = 0.008). No complications were reported during the postoperative follow-up period in this study.”

Our question for the authors are. 1) How deep was the demarcation line?

2) was any comparison made to conventional cross linking?

Other papers or followup studies should be address the questions.
