To evaluate reading performance of patients with monofocal intraocular lenses (IOLs) (Acrysof SN60WF) with or without reading glasses under bright and dim light conditions.

Evaluation of a diagnostic test or technology.
In pseudophakic patients, the spherical refractive error was limited to between +0.50 diopter (D) and -0.75 D with astigmatism of 0.75 D (mean spherical equivalent: right eye, -0.08 ± 0.43 [SD]; left eye, -0.15 ± 0.35). Near addition was +2.75 D. Reading performance was assessed binocularly with or without reading glasses at an illumination of 100 candelas (cd)/m(2) and 4 cd/m(2) using the Radner Reading Charts.
In the 25 patients evaluated, binocularly, the mean corrected distance visual acuity was -0.07 ± 0.06 logMAR and the mean uncorrected distance visual acuity was 0.01 ± 0.11 logMAR. The mean reading acuity with reading glasses was 0.02 ± 0.10 logRAD at 100 cd/m(2) and 0.12 ± 0.14 logRAD at 4 cd/m(2). Without reading glasses, it was 0.44 ± 0.13 logRAD and 0.56 ± 0.16 logRAD, respectively (P < .05). Without reading glasses and at 100 cd/m(2), 40% of patients read 0.4 logRAD at more than 80 words per minute (wpm), 68% exceeded this limit at 0.5 logRAD, and 92% exceeded it at 0.6 logRAD. The mean reading speed at 0.5 logRAD was 134.76 ± 48.22 wpm; with reading glasses it was 167.65 ± 32.77 wpm (P < .05).
A considerable percentage of patients with monofocal IOLs read newspaper print size without glasses under good light conditions.
评估单焦点人工晶状体（IOL）（Acrysof SN60WF）患者在明亮和昏暗光线下戴或不戴阅读镜的阅读表现。

诊断测试或技术的评估。
在无晶状体患者中，球镜屈光度限制在+0.50 屈光度（D）至-0.75 D 之间，散光为 0.75 D（平均等效球镜：右眼-0.08±0.43[标准差]；左眼-0.15±0.35）。近附加为+2.75 D。在 100 坎德拉（cd）/平方米和 4 cd/m²的照明下，使用 Radner 阅读图表双眼评估阅读表现。
在 25 名评估的患者中，双眼平均矫正远视力为-0.07±0.06 logMAR，未矫正远视力为 0.01±0.11 logMAR。在 100 cd/m²时，戴阅读镜的平均阅读视力为 0.02±0.10 logRAD，在 4 cd/m²时为 0.12±0.14 logRAD。不戴阅读镜时，分别为 0.44±0.13 logRAD 和 0.56±0.16 logRAD（P<.05）。不戴阅读镜，在 100 cd/m²时，40%的患者每分钟阅读 80 字以上可达到 0.4 logRAD，68%的患者超过 0.5 logRAD，92%的患者超过 0.6 logRAD。0.5 logRAD 时的平均阅读速度为 134.76±48.22 wpm；戴阅读镜时为 167.65±32.77 wpm（P<.05）。
相当一部分单焦点 IOL 患者在良好的光线下不戴眼镜可以阅读报纸印刷字体。
