摘　　要：目的:观察和评价夜戴型角膜塑形镜矫治儿童屈光参差的临床效果。方法:对屈光参差患儿38例给予角膜塑形镜进行矫正。戴镜后1d;1wk;1,3,6mo;1,2,3a进行随诊,观察裸眼视力、角膜曲率、眼轴长度、裂隙灯检查有无并发症的发生。结果:戴镜后1d裸眼视力有大幅提高,在1wk后稳定。个别病例有轻微的结膜炎及点状角膜上皮剥脱,经治疗后均可恢复;角膜曲率变平,配戴角膜塑形镜前平均角膜曲率为43.42±1.17D,戴镜1wk后,平均角膜曲率为41.65±1.56D,与配戴前比降低,有统计学意义(P<0.01);戴镜1,3,6mo;1,2,3a后无明显变化,无统计学意义(P>0.05);戴镜1,2和3a后眼轴较前增长为0.18±0.13,0.22±0.11和0.25±0.10mm,与戴镜前比无明显统计学意义(P>0.05)。结论:角膜塑形镜是青少年屈光参差的首选治疗方法,它可以充分矫治屈光参差,达到双眼平衡,并且可以有效地控制近视发展,进而减小屈光参差的度数差距。AIM：To observe and evaluate the efficacy of wearing orthokeratology lens for anisometropia.METHODS：Totally 38 patients with anisometropia were fitted with orthokeratology lens.They were followed up 1 day,1 week;1 month,3,6 months;1 year,2,3 years after wearing glasses,and uncorrected visual acuity,corneal curvature,axial length,slit-lamp examination with or without complications were observed.RESULTS：The uncorrected visual acuity was significantly improved,and it was stable after 1 week.Individual cases with conjunctivitis and punctate epithelial exfoliation could be restored after treatment.Corneal curvature flattened,the average corneal curvature was 43.42±1.17D before wearing glasses,and was 41.65±1.56D one week after wearing glasses,the differences were statistically significant（P0.01）.After wearing glasses for 1 month,3,6 months,1 year,2 3 years,there were no significant changes.There was no statistically significant difference（P0.05）.After wearing glasses for 1 year,2,3 years,the axial length increased by 0.18±0.13,0.22±0.11,0.25±0.10mm than before wearing glasses,and there was no statistically significant difference（P0.05）.CONCLUSION：Orthokeratology appears to be a preferred treatment for juvenile anisometropia,it can correct anisometropia,achieve the balance between two eyes,and it also can effectively control the development of myopia,thereby reducing the gap the degree of anisometropia.
