title: [Vision change and quality of life in the patients with cataract].
abstract: OBJECTIVE
  We tried to assess the relationship between quality of life and visual impairment and restoring of patients with cataract and explore the factors which affect quality of life of patients with cataract.
  
  
  METHODS
  The 142 cases of cataract with different visual impairment and the 33 cases of cataract prior to surgery and at 3 months after cataract extraction and intraocular lens implantation were measured by the scale of quality of life for diseases with visual impairment.
  
  
  RESULTS
  The scores of quality of life and their subscores were significantly associated with the visual acuity of patients with cataract. The scores of quality of life between preoperation and after surgery had significantly difference. The factors which affect quality of life of patients with cataract included visual impairment, age and occupations.
  
  
  CONCLUSIONS
  Visual impairment that caused by cataract would cause decline in quality of life. Cataract surgery was effective in improving visual acuity and quality of life of the patients. Measuring quality of life would afford a new method for evaluating visual impairment of cataract.
