title: [The clinical investigation of early visual function in cataract patients after implantation with aspheric intraocular lens].
abstract: OBJECTIVE
  To initially evaluate the early visual function after implantation with aspheric intraocular lens
  
  
  METHODS
  Eighty-eight subjects (91 eyes) were divided randomly into three groups: AcrySof IQ (SN60WF) group, KS-3Ai group and AcrySof Natural (SN60AT) group. Best corrected visual acuity was observed 1 day, 1 week and 1 month postoperatively, while contrast sensitivity and subjective vision were observed 1 month later.
  
  
  RESULTS
  Best corrected visual acuity was obviously better in KS-3Ai group than in the other groups 1 day postoperatively (P < 0.05), but no significant difference was found 1 week and 1 month later among the groups (P > 0.05). When the pupil diameter was in 2.5 to 4.0 mm and 5.0 to 6.0 mm, AcrySof IQ and KS-3Ai groups were better than the AcrySof Natural group in the low and middle spatial frequency (P < 0.05). However, there was no significant difference between AcrySof IQ and KS-3Ai groups (P > 0.05). VF/QOL questionnaire was obtained, showing that implantation with AcrySof IQ and KS-3Ai satisfied patients preferably.
  
  
  CONCLUSIONS
  Aspheric intraocular lens can greatly improve patients' contrast sensitivity and quality of vision.
