Abstract:
Purpose . To report the visual, refractive, and corneal topography and wavefront aberration results of accelerated corneal cross-linking (CXL) during a 24-month follow-up. Methods . Forty-seven eyes underwent riboflavin-ultraviolet A-induced accelerated CXL treatment (30 mW/cm 2 with a total dose of 7.2 joules/cm 2 ). Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical and cylindrical values, keratometry ( K ) measurements ( K s t e e p , K f l a t , K a v g , and K a p e x ), central corneal thickness, and anterior corneal aberrometric analyses including total wavefront error (WFE), total high order aberration (HOA), astigmatism, trefoil, coma, quadrafoil, secondary astigmatism, and spherical aberration were evaluated. Results . The mean UDVA and CDVA were significantly improved at 1 ( p = 0.003 and p = 0.004 , resp.) and 2 years after treatment ( p = 0.001 and p = 0.001 , resp.). The mean K s t e e p , K f l a t , K a v e r a g e , and K a p e x values were significantly lower than baseline at 12 months ( p = 0.008 , p = 0.024 , p = 0.001 , and p = 0.014 , resp.) and 24 months ( p = 0.014 , p = 0.017 , p = 0.001 , and p = 0.012 , resp.). Corneal thickness showed a significant decrease at 1 month. Total HOA and coma decreased significantly at the 12-month ( p = 0.001 and p = 0.009 , resp.) and 24-month visits ( p = 0.001 and p = 0.007 , resp.). Conclusion . Accelerated CXL (30 mW/cm 2 ) was found to be effective in improving UDVA, CDVA, corneal topography readings, total HOA, and coma aberrations during the 24-month follow-up.
