Abstract Details

Purpose:

To compare the visual, refractive and topographic outcomes of corneal collagen crosslinking for progressive keratoconus in pediatric and adult age groups.

Setting:

Prospective study

Methods:

Twenty-two patients younger than 19 years and 21 patients older than 19 years with progressive keratoconus who underwent standart collagen crosslinking (CXL) procedure and followed for 36 months were enrolled into this sudy. Uncorrected diastance visual acuity (UDVA), best corrected distance visual acuity (CDVA), manifest refraction, corneal topography and biomicroscopy findings were evaluated at baseline and at all postoperative follow-up examinations.

Results:

The mean age of patients was 15.8±2.1 years in the pediatric group and 21.0±2.4 years in the adult group. At month-36, the mean improvement in UDVA was 1.9±1.9 Snellen lines versus 0.9±0.2 Snellen lines, the mean improvement in CDVA was 2.5±2.3 Snellen lines vs 0.2±1.8 Snellen lines(p=0.002) in pediatric and adult age groups, respectively. The mean improvement in MRSE was 0.38±2.92 D in pediatric group and 1.97±3.57 D in adult group. The mean improvement in topographic astigmatism was 9.86±4.35 D in pediatric group and 8.20±4.16 D in adult group(p=0.02). The mean flattening in K max was 1.23±2.11 D versus 1.24±2.03 D in pediatric and adult age groups, respectively.

Conclusions:

Corneal collagen crosslinking halts keratoconus progression and improves visual acuities and topographic astigmatism at all ages, however, the improvement in CDVA was significantlly more in pediatric patients compared to adults at postoperative month-36.
