摘要
目的：评价硬性透气性角膜接触镜（rigid gas permeable contact lens,RGP）矫正高度近视及散光的效果。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。
AlM： To evaluate the effect of rigid gas permeable contact lens （ RGP ） in correcting high myopia and astigmatism.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＆lt;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.CONCLUSlON：RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.
