title: [Importance of asferic treatment of intraocular lenses in contrast sensitivity of the human eye].
abstract: OBJECTIVE
  Clinical study which follows the influence of asphericity of intraocular lenses on an important parameter of quality of vision in operated cataract patients - contrast sensibility.
  
  
  METHODS
  This is a pilot, prospective study with 131 eyes of 124 patients, which had cataract surgery by phacoemulsification between 2011-2012. All operations were done by the same surgeon. EXCLUSION CRITERIAS WERE: VA ( 0.7; postop refraction >0.75 D sf. or 0.75 D cyl, corneal diseases, optic nerv or retinal pathologies, atypical surgery, pupil diameter 3 mm. Postoperative control was done at six weeks and included : AV, optical correction, contrast sensibility testing, intraocular pressure, posterior pol exam. Contrast sensibility testing was done using a LCD device, in fotopic condition, CC-100 TOPCON.
  
  
  RESULTS
  Contrast sensibility graphics were compared between spheric and aspheric lenses for Zeiss, AMO, Bausch&Lomb, Alcon.
  
  
  CONCLUSIONS
  There were no statistically significant differences between aspherical lenses. Also, there were no differences for the same manufacturer between spherical and aspherical lenses.
