title: Establishment of a Registry to Monitor Trends in Cataract Surgical Procedures and Outcomes in Israel, 1990-2014.
abstract: BACKGROUND
  Cataract extraction is the most commonly performed ophthalmic surgical procedure. There is no registry for documenting cataract surgical procedures and the overall risk of its complications overtime in Israel.
  
  
  OBJECTIVE
  To present trends in the number and type of selected parameters associated with cataract surgical procedures in Israel between 1990 and 2014.
  
  
  METHODS
  Questionnaires had been sent annually to all surgical centers in which cataract surgery was performed in Israel during the study period. The trends that were investigated included annual rates, surgical sites, surgical techniques, use of an intraocular lens (IOL), and type and rates of postoperative endophthalmitis (POE).
  
  
  RESULTS
  A total of 812,112 cataract surgical procedures were reported during the 25 year study period. Responses to the questionnaire increased from 75% in 1990 to 100% in 2006 onwards. The annual number of reported cataract surgical procedures increased from 16,841 (3.5 per 1000) in 1990 to 57,419 in 2014 (6.9 per 1000), representing an increase of 197%. There was a shift from performing the surgery in the public health system to private medical centers. The surgical technique changed from predominantly manual extracapsular cataract extraction (56% in 1999) to predominantly phacoemulsification (98.7% in 2014). POE rates decreased from 0.25% in 2002 to 0.028% in 2014.
  
  
  CONCLUSIONS
  There was a continuous increase in the rate of surgical cataract procedures, and more were performed in private medical facilities. There was also a major shift towards advanced cataract procedures and a decreased rate of POE.
