Abstract Details


To conduct analysis of medical records of adolescents with advanced stages of keratoconus (KC) in late terms after epikeratoplasty and penetrating keratoplasty.


UFA Eye research institute, UFA, Russia.


Over the 2008 to 2013 period Ufa Eye Research Institute performed surgeries in18 patients (16 boys, 2 girls) aged 16,9 ± 1,1 years. EKP was performed in 16 adolescents (18 eyes) with KC including 9 (11 eyes) with the 3d stage, 1 (1 eye) with the 4th stage and 4 patients (4 eyes) with acute KC. PKP was performed in 1 patient (1 eye) with the 4th stage and 1 (1 eye) with acute KC. Intact donor cornea was transplanted. No complications during and after surgery were observed.


Stabilization of process and improvement of the visual functions were observed in all cases during the 3 year follow-up period. Uncorrected visual acuity increased from 0,035 ± 0,07 to 0,35 ± 0,09, corrected visual acuity – up to 0,54 ± 0,07, central corneal thickness was equal to 389 ± 1,26 to 740,1 ± 1,16 um, the refractive power of the cornea lowered from 62,5 ± 0,7 to 45,9 ± 0,9 D. After PKP in both children the graft remained transparent during the follow-up period of five years, visual acuity was above 0.2, and 0.6, respectively.


Epikeratoplasty as well as penetrating keratoplasty at advanced stages of keratoconus in adolescents is an optimal treatment solution enables to stabilize the disease and improve visual function.
