Purpose:
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.
Setting:
Hayashi Eye Hospital, Fukuoka, Japan.
Methods:
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.
Results:
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
Conclusions:
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.
