title: [Vision analysis of cataract extraction with intraocular lens implantation in venerable aged patients].
abstract: OBJECTIVE
  To evaluate possible diseases affecting visual acuity in cataract extraction with intraocular lens implantation in venerable aged patients.
  
  
  METHODS
  387 patients (425 eyes) over 80 years old were performed cataract extraction and intraocular lens(IOL) implantation, The postoperative vision was observed and affecting factors were analysed.
