摘　　要：目的观察角膜塑型术(OK镜)对青少年近视防治的近期、远期效果,为青少年近视防治提供依据。方法对270例(525只眼)近视青少年验配OK镜,对其裸眼视力和屈光度改变进行4 a的临床观察。结果治疗1 a后裸眼视力恢复并保持正常(≥5.0)者的比率矫正前屈光度≤-3.00 D组为96.61%(228/236),-3.25^-5.00 D组为55.12%(113/205),≥-5.25 D组只有5.95%(5/84)。但近视度数仍出现上升趋势,屈光度增长超过-1.00D的比率矫治1 a后为0,2 a后为2.29%(12/525),3 a后为7.24%(38/525),4 a后为16.95%(89/525)。结论对低于-5.00D的近视,OK镜的近期、远期效果均明显,但仍不能完全控制近视进展。Objective To observe the effects of orthokeratology lenses（OK） on myopia adolescents, and to provide evidence for their prevention against myopia. Methods A four-year elinical observation was carried on 270 myopia adolescents （525 eyes） whose eyesight were corrected by OK. The change of uncorrected visual acuity （UVA） and myopia diaopters were observed. Results After one year, percentages of adolescents whose UVAs were recovered （≥5.0） were 96.61%, 55.12% and 5.95% in ≤ - 3.00D group, - 3.25 - - 5.00D group and ≥- 5.25D group respectively. Percentages of adolescents whose myopia dipters had increased over 1.00D were 0, 2.29% （12/525）, 7.24% （38/525） and 16.95（89/525） after one year, two years, three years and four years respectively. Conclusion Orthokeratology has apparent and stable effects on adolescents＇ myopia, especially on those whose UVA -5.00D. However, it cannot complete control myopia yet.
