Abstract Details


This study aimed to investigate the differences in values of K1 and K2 readings, the central corneal thickness (PAH ) before the collagen crosslinking procedure (CXL) and 3, 6, 12 months later.


The study was done at Eye Policlinic 'Dr.Sefić' in Sarajevo, BiH. We used WaveLight Allegro Oculyzer produced by Alcon (corneal biomechanical parameters).


64 eyes were evaluated in retrospective cross sectional study. The corneal biomechanical parameters were taken with WaveLight Allegro Oculyzer produced by Alcon before the CXL , 3,6, 12 months after the procedure. The curvature of K1 reading and K2 reading were taken and the central corneal thickness were considered due to the time after CXL.


The value of K1 reading before the treatment was 48,8 diopters and was statistically significant lower compering to the value of K1 3 months after the CXL procedure 46,30 D (p=0,0006), K1 reading one year post CXL was 47,20 D (p=0,002). K2 reading before the CXL was 52,65 D, 3 months after the procedure was 51,4, 6 months later 48,55 D, 12 months later 51,30 D. There is statistically significant lower value of K2 reading 6 months after the treatment comparing to the values 3 months postoperatively(p=0,014). However there is significantly lower values of K2 reading 12 months postoperatively comparing to preoperative period(p=0,006).There is statistically significant lower values of pachymetry 12 months after CXL comparing to the values preoperatively (p=0.032).


After CXL in keratoconic eyes there is significant decrease in central corneal thickness 3 and 6 months later but is almost the same 12 months later. However K2 (Kmax) reading is significantly changed 3 and 6 months later and is followed by changing of K1 reading.
