摘　　要：配戴DIMS(Defocus incorporated multiple segments)镜片是目前应用比较成熟的近视管理方法,且通过6年的临床观察发现,长期配戴该镜片可获得持续、稳定、有效的近视管理效果。然而,以往评估近视管理效果主要是以测量等效球镜度和眼轴的进展为主,未能准确给出配戴DIMS镜片对散光变化的影响。通过回顾分析儿童青少年坚持配戴DIMS镜片6个月和12个月后的数据发现,所有入组儿童在配戴期间所产生的等效球镜度变化与球镜变化之间没有显著差异(P>0.05),说明等效球镜度变化基本来源于球镜变化。结果显示,配戴DIMS镜片可以达到良好的近视防控效果,且不会对散光变化产生不利影响,儿童青少年在配戴DIMS镜片期间所出现的散光变化可以忽略不计。DIMS(Defocus incorporated multiple segments)lens represents a relatively advanced method for myopia management at present.Through six years of clinical observation,it has been demonstrated that prolonged use of this lens yields sustained,stable,and effective outcomes in myopia control.However,previous evaluations primarily focused on measuring the progression of spherical equivalent(SE)and axial length(AL),failing to accurately assess the impact of DIMS lenses on astigmatism.A retrospective analysis involving adolescents and children who wore DIMS lenses for 6 months and 12 months revealed that all participants exhibited favorable results in myopia prevention and control during follow-up periods.Notably,there was no significant difference observed between changes in spherical equivalent lens measurements compared to those of spherical lenses during the wearing period(P>0.05).This indicated that variations in spherical equivalent were predominantly attributable to changes in spherical lens measurements.In conclusion,based on the aforementioned data analysis and existing literatures,it could be asserted that wearing DIMS lenses effectively contributes to myopia prevention and control without adversely affecting astigmatism changes.Furthermore,the alterations in astigmatism observed in adolescents and children during the use of DIMS lenses were negligible.
