基于双眼视功能的角膜塑形术联合视觉训练干预儿童近视的临床效果评价OA

Objective To analyze the clinical effect of corneal reshaping surgery based on binocular visual function(Ortho-K)combined with visual training in the intervention of children's myopia.Methods 90 cases(180 eyes)of chil-dren with myopia admitted to our hospital from January 2024 to January 2025 were selected as the research subjects.They were randomly divided into the combined group(Ortho-K combined with VT intervention,n=45)and the control group(simple Ortho-K intervention,n=45).Follow-up was conducted for 12 months,and the pre-and post-intervention uncorrected visual acuity(UCVA),spherical equivalent(SE),accommodation lag(Lag),axial length(AL),accommodation amplitude(AMP),positive relative accommodation(PRA),negative relative accommodation(NRA),and adverse reactions were compared between the two groups.Results After 12 months of intervention,the absolute values of LogMAR and SE in the combined group were both lower than those in the control group(P＜0.05);the reduction in LogMAR in the combined group was greater than that in the control group(P＜0.05),and the increase in the absolute value of SE was less than that in the control group(P＜0.05).After 12 months of intervention,the Lag in the combined group was lower than that in the control group(P＜0.05);the reduction in Lag in the combined group was greater than that in the control group(P＜0.05).Before intervention and 12 months after intervention,there was no statistically significant difference in AL between the two groups(P＞0.05);the growth in AL in the combined group was less than that in the control group(P＜0.05).After 12 months of inter-vention,the AMP in the combined group was higher than that in the control group(P＜0.05);the growth in AMP in the combined group was greater than that in the control group(P＜0.05).After 12 months of intervention,the absolute value of PRA in the combined group was greater than that in the control group(P＜0.05),and NR A was higher than that in the control group(P＜0.05);the increase in the abso-lute value of PRA and the increase in NRA in the combined group were both greater than those in the control group(P＜0.05).There were no serious adverse reactions in both groups,and there was no statistically significant difference in the incidence of mild corneal staining(P＞0.05).Conclusion Ortho-K combined with VT based on binocular visual function intervention can synergistically delay the progression of children's myopia and effectively improve the accommodation func-tion,which is worthy of clinical promotion and application.
