Abstract Details


To evaluate the 2 years results of accelerated corneal collagen cross-linking (CXL) in the managment of progressive keratoconus.


Beyoglu Eye Research and Training Hospital, Istanbul, Turkey


77 eyes of 77 patients were included in this retrospective study. All patients underwent accelerated CXL at an irradience of 30 mW/cm2 for 4 minutes (total surface dose 7.2 J/cm2). Topografic findings ( K flat, K steep, K apex, K average and thinnest corneal thickness (TCT)) were evaluated at baseline and follow-up visits during 2 years.


Mean ± SD age of 29 female and 48 male was 20.11± 6.27 years. K flat value decreased from baseline by 46.16 ± 2.73 D to 45.88 ± 2.70 D at last visit, and the K steep value decreased from 50.32 ± 3.95 D to 49.92 ± 3.83 D (P<0.05 for both) K average value decreased from 48.08 ± 3.15 D to 47.80 ± 3.07 D and the K apex decreased from baseline by 56.65 ± 5.05 D to 55.62 ± 4.78 D at last visit (P<0.05 for both) The TCT was 464.16 ± 23.82 μm preoperatively while it was 471.15 ± 25.16 μm at 24 months postoperatively. (P<0.05)


Accelerated CXL (30 mW/cm2) was found effective at stabilization of progressive keratoconus without any side effects during 24 months follow up.
