title: Change in health-related quality of life after cataract surgery in a population-based sample.
abstract: OBJECTIVE
  To assess the long-term outcomes from cataract surgery on self-rated health, and health-related quality of life (HRQOL) in a population-based older sample.
  
  
  METHODS
  Participants of the Blue Mountains Eye Study at the baseline (n=3654), 5 (n=2335), and 10-year follow-up (n=1952) were interviewed and examined. Questionnaires included an assessment of self-rated health and HRQOL using the 36-item Short-Form Health Survey (SF-36). Incident cataract surgery was defined if participants had cataract surgery since baseline, and confirmed via lens photographic grading.
  
  
  RESULTS
  There was no statistically significant difference in the proportions of participants who experienced a change in self-rated health between those who had incident cataract surgery (14.1% improvement; 29.1% deterioration) and non-surgical subjects (16.7% improvement; 27.0% deterioration). We found no association between incident cataract surgery and the odds for 10-year change in self-rated health, after multivariate adjustment. In contrast, participants who had incident cataract surgery had a significant improvement in the mean scores of 'mental health' domain of HRQOL (+1.60 vs-2.04, P=0.02) and in the mental component score (+1.43 vs-0.82, P=0.02) than participants who did not undergo surgery. Cataract surgery during follow-up had no significant influence on change in mean scores of other domains or in their physical component score of the SF-36 (-2.57 in participants who had incident surgery vs-2.29 in non-surgical participants, P=0.78).
  
  
  CONCLUSIONS
  We confirmed long-term improvement following cataract surgery in the mental but not in the physical domain of the SF-36 or in answers to a specific self-rated health question.
