Abstract

Purpose: The purpose of this study was to measure improvement in best corrected visual acuity with rigid gas permeable (RGP) contact lenses compared to best corrected spectacle visual acuity for patients with irregular astigmatism.

Methods: We compared best corrected visual acuity obtained with spectacle correction to best corrected visual acuity obtained with rigid gas permeable contact lenses for forty-eight eyes of 29 patients with irregular astigmatism.

Results: Patients with 20/20 spectacle visual acuity achieved, on average, no improvement in visual acuity with RGP contact lenses. Patients with 20/25-20/30 spectacle visual acuity achieved a one line average improvement. Patients with 20/40 spectacle visual acuity achieved a two line average improvement. Patients with 20/50-20/200 spectacle visual acuity achieved a four line average improvement and patients with spectacle visual acuity of 20/400, a six line average improvement.

Conclusions: RGP contact lenses can provide a significant improvement in visual acuity compared to spectacle correction for patients with irregular astigmatism.

目的:本研究的目的是测量非规则散光患者使用硬质透气性(RGP)隐形眼镜与使用最佳矫正眼镜的视力的改善。方法:对29例不规则散光患者48眼进行眼镜矫正与硬性透气隐形眼镜矫正后最佳矫正视力的比较。结果:眼镜视力为20/20的患者配戴RGP隐形眼镜后视力平均无改善。20/25-20/30眼镜的患者视力平均改善一条线。配戴20/40眼镜的患者视力平均改善2条线。眼镜视力为20/50-20/200的患者平均改善4线，眼镜视力为20/400的患者平均改善6线。结论:与眼镜矫正相比，RGP隐形眼镜对不规则散光患者的视力有明显改善。
