高非球微透镜对儿童青少年低度近视的控制效果

目的：探讨高非球微透镜对低度近视的控制效果。方法：前瞻性研究。收集2022-05-1/31在我院就诊的7-12岁低度近视患者100例。根据配镜意愿分为两组：配戴单光眼镜组50例、配戴高非球微透镜组50例，均取右眼参数分析。比较两组戴镜后6mo，1a近视增长量(绝对值)、眼轴(AL)增长量、低度近视进入中度近视率、AL负增长率的差异。结果：两组患者戴镜6 mo，1 a后配戴高非球微透镜组近视度数增长量低于配戴单光眼镜组，AL增长量小于配戴单光眼镜组(均P<0.001)； 戴镜6 mo AL负增长率明显高于配戴单光眼镜组(P<0.001)； 两组患者进入中度近视率无差异(P=0.62)； 但戴镜1a后配戴高非球微透镜组进入中度近视率明显低于配戴单光眼镜组(P<0.001)，两组间AL负增长率差异无统计学意义(P=0.12)。对比配戴单光眼镜组患者，配戴高非球微透镜对低度近视患者6 mo近视度数增长控制率为88.2%，AL增长控制率为90.0%，低度近视进入中度近视控制率为66.7%； 戴镜1 a近视度数增长控制率为75.6%，AL增长控制率为69.2%，低度近视进入中度近视控制率为88.9%。结论：对于7-12岁的低度近视儿童青少年，高非微透镜在控制近视效果上远优于单光眼镜，是低度近视防控的优质手段之一。

Control effect of high aspherical lenticule in children and adolescents with low myopia

AIM:To explore the effect of high aspherical lenticule on controlling low myopia.METHODS: Prospective study. A total of 100 patients aged 7 to 12 years old with low myopia who visited our hospital from May 1 to 31, 2022 were collected. They were divided into two groups with 50 cases in each group according to the wishes of patients. The control group was given single vision glasses after optometry, while the study group was given high aspherical lenticule. The myopia progression(absolute value), axial length(AL)growth, transition rate to moderate myopia, and AL negative growth rate over 6 mo and 1 a were compared between the two groups.RESULTS: The myopia progression and the AL growth of study group was lower than that of the control group after 6 mo and 1 a(all P<0.001).The negative growth rate of AL after 6 mo of treatment was significantly higher than that of the control group(P<0.001). The transition rate to moderate myopia between the two groups was not statistically significant(P=0.62); while the transition rate to moderate myopia in the study group was significantly lower than that in the control group after wearing lens for 1 a(P<0.001), and there was no statistically significant difference in AL negative growth rate between the two groups(P=0.12). Compare with single vision glasses, high aspherical lenticule achieved an 88.2% control rate for low myopia progression over 6mo and a 90.0% control rate of AL growth. The control rate for low myopia to moderate myopia was 66.7%; while the control rate of myopia progression growth was 75.6% after wearing lens for 1a, the control rate of AL growth was 69.2%, and the control rate of the transition rate to moderate myopia was 88.9%.CONCLUSION: For children and adolescents aged 7 to 12 with low myopia, high aspherical lenticule was more effective than single vision glasses in controlling myopia, making it one of the optimal choices for myopia control.
