title: Cataract free zone and primary health care approach to prevention of blindness in Shunyi county of Beijing.
abstract: OBJECTIVE
  To establish a three-level eye care network, together with a referral and monitor system for the prevention of blindness, with the aim of creating a cataract free zone.
  
  
  METHODS
  Shunyi County with a population of 548364 was chosen as the target site. Our activities included (1) establishment of a County Guiding Committee for the prevention of blindness: (2) training local ophthalmologists and primary eye care personnel: (3) extensive publicity of knowledge for the prevention of blindness: (4) screening for blindness and low vision, (5) cataract surgery as the chief measure for creating a cataract free zone.
  
  
  RESULTS
  A referral and monitor system for cataract blindness was established in 1987. Seven local ophthalmologists, 449 primary eye care health workers and six optometrists were trained. 815 cataract-blind patients were identified. Up to December 1991, 667 patients (737 eyes), accounting for 81.84% of the total, were treated with cataract surgery, 90.64% of these eyes had their sight restored, and 59.66% patients resumed work. A cataract free zone has been created in Shunyi County.
  
  
  CONCLUSIONS
  The prevention of blindness with cataract surgery as the chief measure can dramatically decrease the prevalence of blindness in a relatively short period of time.
