Abstract Details


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


Laser Vision Clinica, Oftalmolgica, Piura, Peru


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 .


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.


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.
