Abstract
Objective To investigate the effect of corneal plastic surgery on stereopsis and dynamic regulation of myopia and the mechanism of myopia. Methods From March 2015-March 2016, 83 cases (166 eyes) myopia children in our hospital were subjected to corneal plastic surgery. The naked eye distant visual acuity, naked eye near visual acuity, naked eye near stereoscopic sharpness, dynamic adjustment function [Near point of accommodation (NP), adjusted sensitivity (AF), negative relative adjustment (NRA), positive relative adjustment (PRA)] and intraocular pressure, anterior chamber depth, central corneal thickness and axial length of children before wearing glasses, wearing glasses 6 months later, wearing glasses 12 months later were compared. Results The distant and near visual acuity, AF and PRA of naked eyes after 12 months wearing glasses were higher than those after 6 months wearing glasses, and all the above indexes were higher than those before wearing glasses , with statistically significant difference (P 0.05). Conclusions Corneal plastic surgery can significantly correct the visual acuity of children, improve their stereovision, control the progression of myopia, improve the ocular adjustment function of children, and its safety is high.
