Abstract

In the present article, authors evaluate the influence of spherical defocus on contrast sensitivity level in patients with monofocal vs bifocal pseudophakia. The study included 27 patients (30 eyes) after cataract surgery, in whom contrast sensitivity in the setting of different illumination conditions at spherical defocus of different degree and sign was tested. To measure contrast sensitivity Optec® 6500 was used. Mann-Whitney U-test was used to compare results between groups. It was established that illumination level and defocus degree exert different influence on contrast sensitivity in patients with monofocal and bifocal pseudophakia.
