title: Age-related utilisation of cataract surgery in Sweden during 1992-1999. A retrospective study of cataract surgery rate in one-year age groups based on the Swedish National Cataract Register.
abstract: OBJECTIVE
  To study the utilisation and increase of first eye cataract surgery in one-year age groups between 60 and 90 years of age during 1992-1999.
  
  
  METHODS
  Data was extracted from the National Swedish Cataract Register (NCR) that covers about 93.2% of all cataract extractions performed in Sweden during 1992-1999. The total number of living persons in each one-year age group was collected from the Year Book of Statistics in Sweden (1993-2000).
  
  
  RESULTS
  The number of cataract extractions in Sweden increased by 54.8% from 1992 to 1999. The rates of first eye cataract surgery in one-year age groups between 60 and 90 years of age were different for females and males and this difference did not change during a 37% increase of the surgery volume from 1992 to 1999. The rate of first eye cataract surgery increased significantly both for females (+29.4%) and males (+27.2%) during 1992 to 1999 in Sweden.
  
  
  CONCLUSIONS
  The rate of first eye cataract surgery increased significantly from 1992 to 1999 but the gender difference in age-related utilisation of surgery remained unchanged. The increase in rate was about the same in all age groups.
