We compared the visual performance of toric intraocular lenses (IOLs) and non-toric IOLs made of the same material.
The subjects included patients implanted with either Acrysof IQ toric IOLs (SN6AT3-9) or Acrysof IQ IOLs (SN60WF) bilaterally. The toric group included 103 patients who were implanted with Acrysof IQ toric IOLs bilaterally. The non-toric group was a corneal astigmatism-matched control group and included 103 patients who were implanted with Acrysof IQ IOLs bilaterally.
The uncorrected distance visual acuity was significantly better in the toric group, whereas the uncorrected 50 cm visual acuity was better in the non-toric group. There was no significant difference in contrast sensitivity (with and without glare) between both the groups. The rate of spectacle dependency for distance vision was significantly lower in the toric group. There were no significant differences between the two groups in all items of the postoperative quality-of-vision questionnaire (25-item Visual Function Questionnaire).
The toric IOLs used in this study reduced spectacle dependency more than the non-toric IOLs and did not compromise the subjective visual function, but the uncorrected 50 cm vision was worse in toric IOL implanted eyes.
我们比较了由相同材料制成的散光型人工晶状体（IOL）和非散光型IOL的视觉性能。
研究对象包括双侧植入Acrysof IQ散光型IOL（SN6AT3-9）或Acrysof IQ IOL（SN60WF）的患者。散光型组包括103例双侧植入Acrysof IQ散光型IOL的患者。非散光型组为角膜散光匹配对照组，包括103例双侧植入Acrysof IQ IOL的患者。
散光型组的未矫正远视力明显更好，而非散光型组的未矫正50cm视力更好。两组之间的对比敏感度（有眩光和无眩光）无显著差异。散光型组远距离视力的眼镜依赖率明显更低。在术后视觉质量问卷（25项视觉功能问卷）的所有项目中，两组之间无显著差异。
本研究中使用的散光型IOL比非散光型IOL更能减少眼镜依赖，且不影响主观视觉功能，但植入散光型IOL的眼睛未矫正的50cm视力较差。
