In this article we evaluated the influence of different surgical methods for correction of residual ametropia on contrast sensitivity at different light conditions and high-order aberrations in patients with bifocal pseudophakia. The study included 45 eyes (30 people) after cataract surgery, which studied dependence between contrast sensitivity and aberrations level before and after surgical correction of residual ametropia by of three methods - LASIK, Sulcoflex IOL implantation or IOL exchange. Contrast sensitivity was measured by Optec 6500 and aberration using Pentacam «OCULUS». We processed the results using the Mann-Whitney U-test. This study shows correlation between each method and residual aberrations level and their influence on contrast sensitivity level.
