方法：采用自身对照方法，对41例近视(平均屈光度-9.03±6.19DS，最大值-23.00DS)、散光(平均-1.41±1.32DC，最大值-5.50DC)患者，共计65眼，用RGP进行矫正，并与患者自身使用框架眼镜，在自然瞳孔下验光的最佳矫正视力进行对比。

结果：近视、散光65眼配制了RGP，RGP基弧(BC)绝大多数位于7.20～8.25mm区间内，度数-9.92±5.96DS。RGP矫正视力达到1.0的占46.2%，0.6以上的占80.1%，框架眼镜矫正视力达到1.0的占28%，0.6以上的占60%。RGP最佳矫正视力为0.81±0.22，框架眼镜的最佳矫正视力为0.66±0.28。RGP的最佳矫正视力优于框架眼镜(P<0.01)。RGP比较框架眼镜最佳矫正视力提高1行以上有40眼(62%)，视力不变有24眼(37%)，视力下降一行的1眼(2%)。

结论：RGP在矫正高度近视、散光方面效果优于普通框架眼镜。

METHODS: Forty-one patients(65 eyes)with myopia(-9.03±6.19DS, maximum -23.00DS)and astigmatism(-1.41±1.32DC, maximum -5.50DC)were fitted with RGP after strict routine ophthalmological examination, objective refraction and subjective refraction. All these patients were followed after 1wk, 1, 3mo and half one year.

RESULTS: Sixty-five eyes were fitted with RGP(-9.92±5.96DS). RGP base curve(BC)was majorly located within the range 7.20～8.25mm. 46.2% eyes with RGP achieved 1.0(BCVA)and 80.1% achieved above 0.6(BCVA). However, with spectacles, the percent was 28%(1.0)and 60%(>0.6), respectively. BCVA of RGP was 0.81±0.22, but BCVA with spectacles was 0.66±0.28, there was statistical significance(P<0.01). There were 40 eyes(62%)fitted with RGP whose vision were enhanced more than 1 line, 24 eyes(37%)whose vision were not changed and 1 eye(2%)whose vision were dropped 1 line.

CONCLUSION: RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.
