摘　　要：目的 探讨用框架眼镜和透气性硬性角膜接触镜（RGPCL）分别对无晶状体眼进行矫正后，两者在矫正视力和处方度数有无差异。方法51例（53眼）无晶状体眼分别接受框架眼镜和RGPCL矫正，记录其矫正视力和处方度数，将框架眼镜处方度数使用12mm镜眼距进行换算后，再对两组数据进行统计学分析。结果发现RGPCL矫正视力明显优于框架眼镜矫正视力，差异有统计学意义；框架眼镜和RGPcL矫正无晶状体眼处方度数，差异无统计学意义。结论用框架眼镜矫正效果可大致预估RGPCL矫正效果，但RGPCL矫正在视力舒适度及双眼视的获得较框架眼镜有不可取代的优势，并且对由于角膜不规则散光等造成的屈光矫正视力不佳，能取得更好的效果。在对无晶状体眼进行光学矫正时，应首选RGPCL。Objective To evaluate the differences of the degree and corrected visual acuity between spectacles and contact lens in correcting aphakic eyes. Method 51 subjects were fitted with both RGP CL lenses and spectacles. They were first examined with corneal topography and refractometry, then were fitted with RGP CL trial lenses and lastly fitted with RGP CL lenses. Take 12 mm as mirror eye distance to calculate patients＇ needed diopters according to formula, then compared with the diopters of RGP CL lens. Resuits The differences of the degree in the two groups are not statistically significant. RGP CL lens provide a significant improvement in visual acuity. Conclusion RGP CL is safe and effective in correcting aphakics.
