目的　比较中高度散光患者配戴框架眼镜和透气性硬性接触镜（RGPCL）的主客观视觉质量。方法　选取2008年6月－2011年5月中高度角膜散光20例共40只眼进行角膜地形图、综合验光仪验光等检查后，选择合适试戴片作配适评估并定制RGPCL。要求患者戴镜后1周、1个月、3个月和6个月复查，记录矫正视力、镜片配适、眼部情况，并在第4次复查时进行对比敏感度视力检查及主观问卷调查。结果　RGPCL矫正视力优于框架眼镜，但两者对比敏感度视力在各空间频率均无明显差异。主观评分时，远视力两者无明显差别；中距离视力框架眼镜评分（3.825 ± 0.245）分，RGPCL评分（3.525 ± 0.302）分，差异有统计学意义（t=5.339，P=0.000）；近距离视力框架眼镜评分（3.795 ± 0.233）分，RGPCL评分（3.690 ± 0.194）分，差异有统计学意义（t=3.462，P=0.030）。有45%患者选择RGPCL为主要配戴方式；40%患者选择RGP CL和框架眼镜交替使用的方式；10%患者选择仅在有特殊社交需求时使用RGPCL；另5%患者放弃使用RGPCL。结论　RGPCL和框架眼镜矫正中高度角膜散光均能取得较满意效果，在中近距离精细作业时框架眼镜矫正视力更为稳定清晰。但由于RGPCL在成像质量和外观上的优势，多数患者仍愿意坚持配戴RGPCL。
