目的：观察轻中度近视青少年配戴夜戴型角膜塑形镜后眼部的早期变化。方法选取我院眼科门诊8~16岁轻中度近视患者31例60眼，按照角膜塑形镜规范验配流程验配，戴镜后1d、1周、1个月、3~6个月后检查视力，屈光度，眼压；角膜形态变化等。结果配戴者1 d视力既有提高，戴镜1周后稳定，球镜屈光度明显减少，眼压变化无统计学意义。角膜地形图3 mm区域角膜曲率平均值下降，戴镜1周后变化有统计学意义（P＜0.05），1个月后变化无统计学意义（P＞0.05）；角膜前表面diff值下降变化有统计学意义（P＜0.05）；后表面diff值变化无统计学意义（P＞0.05）；角膜最薄厚度减少变化有统计学意义（P＜0.05）；前房深度变化无统计学意义（P＞0.05）；white-to-white值变化无统计学意义（P＞0.05）。结论轻中度近视的青少年通过科学合理地配戴高透氧夜戴型角膜塑形镜矫治可以有效地提高裸眼视力，减少角膜屈光度，抑制近视的发展。

Objective To observe the effects of overnight orthokeratology lens on the corneal shape in mild and middle adolescent myopia.Methods Twenty-one mild and middle myopia patients(42 eyes, aging from 8 to 16 years old)had been followed up for one day, one week, one month, three months and six months. All patients wore night orthokeratology lens after standard optometry for spectacles. The corneal shape was measured by OrbscanⅡ.Results Compared with the past, The uncorrected visual acuity was signiifcantly im proved after one day, and it was stable after one week. Corneal curvature flattened, the average corneal curvature became lower after wearing glasses one week, the differences were statistically significant(P<0.05), there was no statistically signiifcant difference(P>0.05)after wearing glasses for one month, three months, six months. There was statistically signiifcant difference(P<0.05)for corneal front surface diff number and the corneal thickness. There was no statistically signiifcant difference(P>0.05)for corneal white-to-white, corneal rear surface diff number and anterior chamber depth.Conclusion The vision can be abvisle increased in mild and middle myopia for teenager with overnight orthokeratology lens. The degree of myopia can be decreased.
