比较角膜塑形镜与多点近视离焦镜片预防青少年近视的效果

Effect Comparison of Corneal Reshaping Lenses and Multi-point Myopic Defocus Lenses for Preventing Myopia of Adolescents

目的探讨角膜塑形镜与多点近视离焦镜片预防青少年近视的效果。方法选取本院2021年7月—2023年6月收治的150例青少年近视儿童,按照等量电脑随机法分为对比组(n=75)和研究组(n=75);对比组予以多点近视离焦镜片佩戴(日间),研究组予以角膜塑形镜佩戴(晚间),展开为期18个月的随访,观察、对比两组戴镜前后屈光度、眼轴及调节功能指标。结果研究组较之对比组,戴镜后屈光度、眼轴更低,组间差异有统计学意义(P<0.05)。两组戴镜后调节功能指标(调节幅度/灵敏度/正、负相对调节)差异较小,对比差异无统计学意义(P>0.05)。结论青少年近视防控中,多点近视离焦镜片与角膜塑形镜的应用均能够促进近视患儿双眼调节功能的改善,并有效控制患儿近视度数的增长;但在近视防控方面,角膜塑形镜的应用更优。

Objective To compare application effect of corneal reshaping lenses and multipoint defocus lenses for preventing myopia of adolescents.Methods The paper chose 150 adolescents and children with myopia admitted to our hospital from July 2021 to June 2023,and divided them into two groups randomly with equal amount computer randomization,control group(n=75)and study group(n=75).Control group was treated with defocused lenses for multi-point myopia(in day time),while study group with corneal reshaping lenses(in night time).After follow-up of 18 months,refractive index,axial length,and regulatory function indicators were observed and compared between two groups before and after wearing glasses.The study was conducted from July 2021 to June 2023.Results Study group had lower refractive index and axial length after wearing glasses than control group,with statistical significance(P<0.05).After wearing glasses,adjustment function indexes(adjustment amplitude/sensitivity/positive and negative relative adjustment)between two groups had little difference,comparison was not statistically significant(P>0.05).Conclusion During myopia prevention and control of adolescents,multi-point defocus lenses and corneal reshaping lenses can improve binocular adjustment function of patients with myopia,and control increase of myopia degree effectively.But corneal reshaping lenses is more optimal for m yopia prevention and control.
