目的：观察角膜塑形镜控制青少年单眼近视的临床效果。

方法：选取2014-06/2016-03于我院视光门诊单眼验配角膜塑形镜的单眼近视患者56例112眼，将配戴角膜塑形镜的眼作为试验组，未作处理的另一眼作为对照组。观察戴镜前和戴镜12mo后屈光度、角膜曲率、眼轴长度变化情况。

结果：戴镜12mo后，试验组屈光度增加量(0.29±0.15D)与对照组(0.76±0.41D)差异显著(t=2.8631，P<0.001)； 试验组水平角膜曲率变化量(0.27±0.11D)与对照组(0.20±0.14D)无差异(t=0.8204，P>0.05)； 试验组眼轴长度增加量(0.14±0.10mm)与对照组(0.32±0.14mm)差异显著(t=2.7518，P<0.001)。

结论：角膜塑形镜可通过减缓眼轴增长来控制近视度数的增加，从而延缓近视的发展。

METHODS: Totally 56 cases(112 eyes)with anisometropia myopia receiving monocular orthokeratology treated were divided into two groups. For every case, eye wearing orthokeratology was assigned to the experimental group and another eye to the control group. The refraction, corneal curvature and axial length were measured at pre-wear and 1mo discontinuation after wearing orthokeratology 1y.

RESULTS: The statistically significant changes(t=2.8631, P<0.001)of increase in refraction were(0.29±0.15D),(0.76±0.41D)for the experimental and control group respectively. The horizontal corneal curvature was(0.27±0.11D)and(0.20±0.14D)for two groups, and there was no statistically significant difference(t=0.8204, P>0.05). The increase of axial length was(0.14±0.10)mm and(0.32±0.14)mm for the experimental and control group, respectively, and the increase was statistically significant(t=2.7518,P<0.001).

CONCLUSION: Orthokeratology can slow down myopia progression by reducing axial length to control myopia increase.
