AIM:According to the analysis of 1061 cases(1061 eyes) of cataract surgery in primary blindness-prevention project,to explore the key processes in perioperative period in order to find a safe and effective procedure.METHODS: According to the information of 1061 cases in the blindness-prevention project in 2009,the perioperative processes were summarized and regulated.RESULTS:Among these 1061 cases who accepted cataract surgery,there were 17.0% cases with the preoperative corrected vision under hand movement,22.1% under 0.1,59.0% between 0.1 to 0.3,and 1.9% better than 0.3.267 cases(25.2%) were hyper matured cataract with/without hard nucleus.There were 2 cases(0.2%) combined with lens dislocation,13 cases(1.2%) accepted anti-glaucoma surgery,3 cases(0.3%) accepted vitrectomy surgery,and 9 cases(0.8%) suffered by obsolescence uveitis,44 cases(4.1%) corneal endothelial cell counting was less than 2000 per square centimetre.Phacoemulsification were performed in 1048 cases(98.8%) and ECCE in 13 cases.The incidence of several primary complications were separately: 27 cases(2.5%) of posterior capsular rapture,54 cases(5.1%) of corneal edema at postoperative 3 days,and 1 case(0.1%) of failure to IOL implantation.None endophthalmitis happened.In 3 months postoperation,the out of blindness rate(uncorrected visual acuity >0.1) was 97.8% and the rate(best corrected visual acuity >0.3) was 84.2%.There were about 36.7% with visual acuity better than 0.6.There were so many cases combined with kinds of fundus diseases,such as retinopathy due to high myopia(3.7%),age-related macular degeneration(3.3%),and so on.CONCLUSION:The conditions of cataract patients who joined in blindness-prevention project were very complex,not only in ocular but also in systemic.The rate combined with fundus diseases was high.In order to make the cataract surgery successful,normative processes in perioperative period are very important.
