Comparative analysis of accommodative ability in children with hyperopia, anisometropia, amblyopia after femtolaser-assisted laser intrastromal keratomileusis

Abstract

Purpose. Analysis of the accommodative ability in children with hyperopic anisometropia, amblyopia of operated amblyopic and paired leading eyes after femtolaser-assisted laser intrastromal keratomileusis (FS-LASIK). Material and methods. In the 1st group were 20 children with hyperopic anisometropia and amblyopia after FS-LASIK. In the 2nd were children receiving conservative treatment. Results. After 6 months, when analyzing the accommodation, the coefficient of the accommodative response (CAR) of amblyopic eye in the 1st group was 0.05±0.07 conv. units, in the 2nd group was -0.1±0.19 conv. units (рm-u=0.03). The microfluctuation coefficient (CMF) of the amblyopic eye was increased, but the CMF of the paired leading eye in children after FS-LASIK approached the norm and amounted to 58.4±5.4 µF / min. In the conservative treatment group CMF remained high and was 60.8±4.44 µF / min (рm-u= 0.08). The objective accommodative response of the amblyopic eye in the 1st group increased by -1.13±0.03 diopters, in the 2nd group – by -0.82±0.48 diopters (рm-u=0.05). Conclusion. FS-LASIK helps to improve the accommodative ability in children with hyperopia, anisometropia and amblyopia. Key words: accommodation, hyperopia, anisometropia, amblyopia, FS-LASIK.
