Abstract Details

Purpose:

to assess the two-year efficacy of femtosecond laser-assisted intrastromal corneal ring segments (ICRS) implantation followed by transepithelial accelerated corneal collagen cross-linking for treatment of keratoconus in children with vernal keratoconjunctivitis .

Setting:

Sohag University Hospital and Future Center, Sohag, Egypt.

Methods:

Fifty two eyes of 27 children with keratoconus and vernal keratoconjunctivitis were included in this retrospective comparative study. Thirty three eyes of 19 children (group A) were treated with femtosecond laser-assisted ICRS implantation followed by transepithelial accelerated corneal collagen cross-linking and nineteen eyes of 11 children (group B) were treated with transepithelial accelerated corneal cross-linking only. Three children had cross-linking in one eye and ICRS plus cross-linking in the other eye.

Results:

In group A; the preoperative mean best-corrected visual acuity (BCVA) was 0.7 ± 0.2 (logMAR) whereas the two-year postoperative mean BCVA was 0.42 ± 0.3. The preoperative average keratometry was 51.5 ± 3.1D, whereas the postoperative average keratometry was 45.5 ± 2.9 D. One eye showed progression of keratoconus and required repeat cross-linking. In group B; the preoperative mean BCVA (logMAR) was 0.3 ± 0.4 whereas the postoperative mean BCVA was 0.28 ± 0.5. The preoperative average keratometry was 47.1 ± 1.9 D, whereas the postoperative average keratometry was 46.2 ± 2.2 D.

Conclusions:

Although femtosecond laser-assisted ICRS implantation followed by corneal collagen cross-linking is effective in the management of keratoconus in children with vernal keratoconjunctivitis, progression is ineviatable in some cases necessitating long-term follow-up.
