ABSTRACT
The standard vision test using Snellen acuity is not always an accurate indicat or of functional vision loss. Acuity measures optical blur, but psudophakic eyes frequently do not affect optical blur. Therefore, acuity cannot provide relevant informations on the loss of vision experienced by the patients. Contrast sensitivity, not acuity, has been shown to be effective in determining functional vision loss due to psudophakic eyes. The MCT 8000(R), glare and contrast sensitivity system. was used for measurement of contrast sensitivity in 19 pseudophakic eyes at postoperative 1 month, 18 pseudophakic eyes at post-operative 3 months and 18 normal control eyes. The results were as follows 1) Contrast sensitivity decreased in pseudophakic eyes compared to normal eyes in four different conditions; day vision, day vision with perpheral glare, night vision and night vision with central glare. 2) In pseudophakic eyes, contrast sensitivity was not different between 1 month and 3 months postoperatively.
