The article presents an analysis of the change of mean spherical equivalent of refraction, uncorrected (UCVA) and maximally corrected (CDVA) visual acuities in 31 children during 6 months ― 1.5 years (mean 9±2.8 month) after surgery and subsequent conservative treatment of amblyopia. All patients underwent FS-LASIK on amblyopic eye; 500 Hz «Microscan» (Troitsk, Russia) eximer laser and 1 MHz «FemtoVisum» (Troitsk, Russia) femtosecond laser were used. Before surgery uncorrected visual acuity (UCVA) was 0.07±0.03, maximal correction (CDVA) was 0.13±0.1. Mean spherical equivalent refraction (SE) of amblyopic eye was +4.34±2.61 D, mean anisometropia was 4.31±1.56 D. Refraction data of the fellow eye were close to emmetropy. In 9 months after FS-LASIK, the mean SE was +1.02±0.28 D (p=0.00), anisometropia ― 0.58±0.34 D (p=0.00), CDVA 0.2±0.04 (p=0.00), UCVA 0.16±0,1 (p=0.00). Predictability of the planned (in order to lessen anisometropia) refractive effect was within ±0.5 D and ±1.0D in 56% and 64% of cases respectively. In 50% of cases CVA increased 1-2 lines. FS-LASIK in children with hyperopia and anisometropia with the Russian-made 1MHz «FemtoVisum» femtosecond laser use proved to be safe and effective.
Key words: refractive surgery in children, anisometropia, amblyopia, femtosecond laser.
