Abstract Details

Purpose:

To evaluate the safety and efficacy of rapid corneal cross-linking in pediatric patients with keratoconus.

Setting:

Laser Vision Clinica, Oftalmolgica, Piura, Peru

Methods:

In this study 15 eyes from 11 patients (age range : 10-18 years ) with keratoconus were evaluated during 12 months postoperatively. All the patients underwent to rapid crosslinking with settings of 9 mW/cm2 for 10 minutes using the UV – X 2000 ( IROC ) device that features an optimized beam profile to maximize the cross-linked volume and provides high intensity illumination which allows shortening treatment time to 10 min. The main outcomes were included : Uncorrected and corrected distance visual acuity ( UDVA – CDVA ),refraction ,keratometry , and topographic measurements by Sirius .

Results:

Mean uncorrected distance visual acuity improved significantly from 1.02 ± 0.40 log MAR (20/200) to 0.74 ± 0.27 log MAR (20 /100 ) and mean CDVA from 0.45 ± 0.18 (20 /60 ) to 0.20 ± 0.10 (20/30) . The flat keratometry value decreased from 47.26 ± 1.67 to 46.77 ± 1.62 diopters and the steep keratometry value decresed from 51.95 ± 2.00 (p < 0.01 for both ) The high order aberrations,coma and astigmatism were also decreased at 12 months after treatment. No complications were noted.

Conclusions:

Rapid Corneal collagen CXL was found to be safe and effective in the first 12 months for keratoconus in children , and no evidence of disease progression was seen at 12 months.
