title: The quality of life associated with presbyopia.
abstract: OBJECTIVE
  To determine the health-related quality of life associated with the presbyopia.
  
  
  METHODS
  Cross-sectional, patient preference-based, time trade-off utility analysis.
  
  
  METHODS
  One hundred and ten patients with spectacle-corrected presbyopia and a best-corrected visual acuity of 20/40 or better were interviewed in a cross-sectional fashion using a standardized, validated, time trade-off utility analysis questionnaire.
  
  
  RESULTS
  The mean utility associated with the health state of presbyopia in our sample was 0.980 (standard deviation, 0.086; 95% confidence interval, 0.964 to 0.996). Ten percent of the cohort had a presbyopia-associated utility of 0.95 or less. Age, gender, level of education, marital status, and the degree of presbyopia did not significantly affect the time trade-off utilities associated with presbyopia.
  
  
  CONCLUSIONS
  Presbyopia corrected with glasses is associated with a nominal decrease in quality of life, similar to that of treated hypertension, for the average person with the condition. Approximately 10% of such patients theoretically may be candidates for an intervention other than spectacles to correct the condition.
