摘要
目的观察周边近视性离焦镜片和渐变多焦点镜片对控制青少年近视发展的作用。方法随机抽取12～14岁配戴周边近视性离焦镜片的青少年近视患者111例(共222只眼),作为甲实验组;随机抽取12～14岁配戴渐变多焦点镜片的青少年近视患者98例(共196只眼),作为乙实验组;随机抽取12～14岁配戴普通单焦点镜片的青少年近视患者165例(共330只眼),作为对照组。戴镜一年后复查并对复查结果进行统计学分析。结果配镜前三组屈光度差异无统计学意义(P>0.05)。一年后甲试验组近视屈光度人均增加(-0.67±0.25)°,乙试验组近视屈光度人均增加(-0.68±0.24)°,对照组近视屈光度人均增加(-0.80±0.26)°。甲试验组与对照组屈光度人均增加差异有统计学意义(P<0.01);乙试验组与对照组屈光度人均增加差异也有统计学意义(P<0.01);甲试验与乙试验组屈光度人均增加差异无统计学意义(P>0.05)。结论配戴周边近视性离焦镜片和渐变多焦点镜片比配戴普通单焦点镜片能在一定程度上缓解青少年近视的发展,"周边近视性离焦"镜片和渐变多焦点镜片对缓解青少年近视的发展无明显差异。
Objective To study the effects of ＂defocus spectacle lenses for peripheral myopia＂ and ＂progressive multi-focal lenses＂ in preventing myopia from increasing in young. Methods Randomly select 111 young myopia patients （222 eyes） of 12-14 years old who wear ＂defocus spectacle lenses for peripheral myopia＂, and treat them as group A. Randomly select another 98 young myopia patients （196 eyes） of 12-14 Years old who wear ＂progressive multi-focal lenses＂, and treat them as group B. Then randomly select another 165 young myopia patients （330 eyes） of 12-1~t years old as a control group who wear ＂Ordinary single focus lenses＂. To have a clinical review and a statistical analysis on all groups a year later. Results There＇ s no statistical significance （P〉0.05） on the diopter difference among the 3 groups before wearing glasses. A year later, in group A, per capita myopia diopter increases （-0.67±0.25）°, in group B, per capita myopia diopter increases （-0.68±0.24）°, while in the control group, per capita myopia diopter increases （-0.80±0.26）°. The difference in per capita diopter increasing between group A and the control group is statistically significant （P〈0.01）. While the difference in per capita diopter increasing between group B and the control group is also statistically significant （P〈0.01）. But the difference in per capita diopter increasing between group A and group B has no statistical significance （P〉0.05）. Conclusion Wearing ＂defocus spectacle lenses for peripheral myopia＂ or ＂progressive multi-focal lenses＂ could slow down myopia increasing in young people to some extent than wearing ＂Ordinary single focus lenses＂.
