To compare all-distance visual acuity and contrast visual acuity with and without glare (glare visual acuity) between phakic eyes with a clear lens and pseudophakic eyes with a monofocal intraocular lens.
Hayashi Eye Hospital, Fukuoka, Japan.
This study comprised phakic), pseudophakic eyes in 4 age groups (40s, 50s, 60s, 70s). Corrected visual acuity from far to near, contrast visual acuity, and glare visual acuity were examined.
The mean corrected intermediate and near visual acuities were significantly better in phakic eyes than in pseudophakic eyes in patients in their 40s and 50s (P<or=.0215); corrected distance visual acuity was similar. In the 60s and 70s age groups, there was no statistically significant difference in corrected visual acuity at any distance. The region of accommodation at which eyes achieved a corrected visual acuity of 20/29 or 20/40 was greater in phakic eyes than in pseudophakic eyes in the 40s and 50s age groups (P<or=.0302) but was similar in 60s and 70s age groups. In all age groups, there were no significant differences in photopic or mesopic contrast visual acuity or glare visual acuity.
In patients in their 40s and 50s, the region of accommodation in phakic eyes was greater than in pseudophakic eyes; the region was similar in patients in their 60s and 70s. Because contrast sensitivity with and without glare was similar at all ages, visual function appeared to be comparable in patients 60 years and older.
比较无晶状体眼和单焦点人工晶状体眼的全距视力和对比视力（眩光视力）。
日本福冈林眼科医院。
本研究包括 4 个年龄组（40 多岁、50 多岁、60 多岁、70 多岁）的有晶状体眼和无晶状体眼。检查远、近矫正视力、对比视力和眩光视力。
在 40 多岁和 50 多岁的患者中，有晶状体眼的中间和近距矫正视力明显优于无晶状体眼（P<0.0215）；远距矫正视力相似。在 60 多岁和 70 多岁的年龄组中，任何距离的矫正视力均无统计学差异。在 40 多岁和 50 多岁的年龄组中，有晶状体眼达到 20/29 或 20/40 矫正视力的调节区域大于无晶状体眼（P<0.0302），但在 60 多岁和 70 多岁的年龄组中相似。在所有年龄组中，明、暗光对比度视力或眩光视力均无显著差异。
在 40 多岁和 50 多岁的患者中，有晶状体眼的调节范围大于无晶状体眼；在 60 多岁和 70 多岁的患者中，调节范围相似。由于所有年龄组的对比敏感度和眩光敏感度相似，因此 60 岁以上患者的视觉功能似乎相当。
