Description The authors examined in a group of patients with cataract the visual acuity and contrast sensitivity before and after cataract surgery. A VF-7 questionnaire was used for subjective evaluation of the result of surgery. The authors did not detect a significant difference of the contrast sensitivity of eyes with a PMMA lens, Acrysof lens or Silicone lens. Only one question in the questionnaire correlated significantly with contrast sensitivity. The authors found a significant reduction of contrast sensitivity caused by an altered transparency of the lens. The decline of contrastsensitivity in eyes with cataract and good visual acuity may be an important factor in indication of cataract surgery.
