Abstract Details


To evaluate the safety and efficacy of accelerated topography guided CXL (corneal crosslinking) for keratoconus treatment.


Kiev Center of therapy and eye microsurgery, Kiev, Ukraine


Accelerated topography guided CXL was performed with the CXL system ( wavelength 365nm, 5 minute irradiance 18.0 mw/cm2 over 7 mm diameter spot, applied to the cone apex. 25 eyes (13 patients, age 20 to 29 years old, 4 women, 9 men) were followed for 6 months after CXL. The following parameters were assessed before CXL and 6 month postoperatively: UDVA (uncorrected distance visual acuity), CDVA (corrected distance visual acuity), TL (cornea's thinnest location), Kmax ( maximum K), TA (topographic astigmatism).


Preoperatively the mean UDVA was 0.25, CDVA was 0.51, TL 450μm, Kmax 58.3D, TA 3.7D. 6 months postoperatively: UDCA was 0.3, CDVA was 0.54, TL 444μm, Kmax 57.1D, TA 3.3D. Thus, flattening of the cornea was 1.2D, topografic astigmatism reduction was 0.4D, improving of UDVA and CDVA 0.05 and 0.03 accordingly, corneal thickness decreased by an average of 6 μm. No severe complications occured.


We found that accelerated topography guided corneal crosslinking is a safe and effective procedure for stabilizing the cornea in case of keratoconus progression.
