Abstract Details

Purpose:

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).

Setting:

Veni-Vidi Eye Hospital, Istanbul, Turkey

Methods:

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.

Results:

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.

Conclusions:

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.
