Long-term follow-up of school-age children on the effectiveness of myopia correction with contact lenses

Introduction and purpose. Early use of contact correction for congenital myopia astigmatism in children adolescents contributes to their social rehabilitation. The with lenses provides sustainability absence periods blurred retinal images, which are experienced the glasses. purpose study was determine, through long-term follow-up, extent lens improves uncorrected maximally corrected visual acuity school-age myopic astigmatism. Material methods. We followed up three years 84 (168 eyes) aged 6–16 manifest refraction astigmatism, who used soft silicone hydrogel aspherical correct ametropia. In early late these patients were examined acuity, objective subjective clinical refraction, axial eye length, corneal thickness diameter, keratometry, phorometric data (accommodation, vergence, disparate areas, oculomotor apparatus interaction). Results.In course monitoring children, statistically significant results recorded after observation, namely: an increase by 47% (t=5.2; p<0.01), vision 8% (t=9.3; spheroequivalent 17% (t=3.7; anteroposterior segment 4% (t=7,1; amplitude accommodation 27% (t=14.6; negative part relative (t=7.3; positive 32% (t=7.1; flexibility 35% (t=14.2; ratio convergence 19% (t=3.4, stereovision 56% (t=4.1; as well a decrease keratometry index strong meridian 2% delays accommodative responses 33% p <0.01), distance phoria 16% (t=10.1; near (t=11.3, p<0.01). Conclusions. has shown that school-aged can maximum acuity. axis (APA) indicates progression myopia, but (SCL) leads changes anterior surface: central zone, its flattening. Improvement accommodation, parts apparatus, interaction also observed. obtained indicate deceleration progression.
