[Contrast sensitivity in aphakia and artiphakia].
Examination of the contrast sensitivity in aphakic eyes corrected by glasses and in artephakias provides information which cannot be obtained by measurement of visual acuity and is thus a suitable supplement of the basic test of visual functions. Contrast sensitivity declines significantly with advancing age. Contrast sensitivity of aphakic eyes corrected by glasses corresponds to values of contrast sensitivity of phakic eyes of the same age group. Artephakias with an iris clip lens have a contrast sensitivity reduced by cca one half as compared with a control group, while in artephakias with a posterior chamber lens there is a decline by one third, as compared with a control groups of the same median age.
