精准自由曲面角膜塑形镜验配技术在儿童青少年近视矫正中的应用效果OA

Objective To explore the application effect of single-used precision free form orthokeratology(SPFO)in correcting myopia in children and adolescents.Methods 104 myopic children and adolescents were selected as the research subjects.They were divided into the SPFO group(52 cases)and the traditional test strip library technology group(52 cases)using random number table grouping.The SPFO group was given SPFO technology for shaping mirror fitting,while the traditional test piece library technology group was given traditional test piece library technology for fitting.Both groups were followed up for 12 months after wearing it.The changes in axial length(AL),uncorrected visual acuity(UCVA),tear film rupture time(BUT),corneal endothelial cell count,and complications after wearing for 3,6,and 12 months of the two groups were compared.Results After wearing for 12 months,both groups showed an increase in AL compared to wearing for 3 and 6 months,and an increase after wearing for 6 months compared to wearing for 3 months.However,after wearing for 12 months,the increase in AL in the SPFO group was less than that in the traditional test strip library technology group(P＜0.05).After wearing for 12 months,both groups of UCVA were higher than those after wearing for 3 and 6 months,and higher than those after wearing for 3 months after wearing for 6 months.Moreover,after wearing for 12 months,the SPFO group was higher than the traditional test strip library technology group(P＜0.05).After wearing for 3,6,and 12 months,the incidence of complications in the SPFO group was lower than that in the traditional test strip library technology group(P＜0.05).Conclusion The application of SPFO technology in correcting myopia in adolescents is superior to traditional tech-niques in terms of AL control,visual improvement,and safety,and was worthy of clinical promotion.
