Abstract Details


To investigate refractive, topometric, pachymetric, and visual rehabilitation changes induced by anterior surface normalization for keratoconus by corneal wavefront-guided (CW) excimer laser ablation in conjunction with corneal cross-linking (CXL).


Veni-Vidi Eye Hospital, Istanbul, Turkey


Twenty four eyes of 17 keratoconic cases subjected to the procedure were studied for visual acuity, keratometry, pachymetry, and anterior surface irregularity indices by wavefront analysis system.


The mean age of the patients was 34.16 years (range 22 to 56 years) and the mean follow-up was 18.5 ± 6.5 months (range 6 to 31 months). Pre-operatively, all eyes had irregular astigmatism ranging from 0.25 to 6.00 diopters (D). The means of pre- and post- operative RMS of high order aberrations were 2.10 ± 1.04 and 1.27 ± 0.66 (p=0.009). The means of pre- and post- operative uncorrected and corrected visual acuities were 0.10±0.04, 0.26 ±0.1 and 0.45 ±0.30, 0.77±0.19 Snellen lines respectively (p1=0.108, p2=0.001).12 eyes (50%) had an increase of more than 5 lines.


Two years outcomes has demonstrated that the procedure is a safe and effective method to arrest keratectasia progression and to improve corneal regularity in keratoconus management.
