abstract: OBJECTIVE
  To decrease the prevalence of blindness and low vision in Laiwu City.
  
  
  METHODS
  The therapeutic effects and postoperative complications of each method of cataract surgery were investigated and statistically analyzed. The cases with postoperative complications were treated after surgery.
  
  
  RESULTS
  In the investigation, 1,274 eyes of 1,089 cases had undergone cataract surgeries, including couching for cataract, intracapsular cataract extraction (ICCE), extracapsular cataract extraction (ECCE) and ECCE with intraocular lens implantation. The prevalence of blindness and low vision was 4.87% and 23.70%, respectively. There were postoperative complications in 650 eyes (51.02%). They were corneal decompensation, secondary glaucoma, opacity of posterior capsuler, cystoid macular edema and retinal detachment. After treatment for the postoperative complications, the prevalence of blindness and low vision was decreased to 1.96% and 6.01%, respectively. The cases having escaped the blindness and handicap after treatment were lowest in the groups of couching and ICCE.
  
  
  CONCLUSIONS
  The survey on the population having undergone cataract surgery in rural district is important. The postoperative complications can be treated in time and the prevalence of blindness and low vision can be decreased.
