Clinical study on rigid gas permeable lenses decreasing the children's anisometropia caused by hyperopia

Abstract

AIM:To investigate the effect of rigid gas permeable lenses(RGP)for the difference of spherical equivalent(△SE)and the difference of axial length(△AL)in children with non-amblyopia anisometropia.METHODS:In department of optometry in our hospital, 95 children 190 eyes aged from 6～12 year-old with hyperopic refractive error, of whom the difference of spherical equivalent between two eyes was 1D≤△SESE and △AL of the two groups were calculated and analyzed statistically. RESULTS:The △SE between two eyes of group A was less than that of group B, and the difference was statistically significant(F=18.508,P=0.002AL between two eyes of group A was less than that of group B, the difference was statistically significant(F=1116.765,P=0.000CONCLUSION:In children with non-amblyopia anisometropia, RGP is very necessary to correct the vision of higher-dioptry eye. And it can significantly reduce the binocular refraction, correct anisometropia, avoid visual function abnormalities caused by anisometropia and so on.
