·AIM:To investigate the effect and safty of small incision non-phacoemulsification cataract extraction combined with intraocular lens(IOL)implantation under topical anesthesia.·METHODS:The cases with cataract in our hospital from January 2007 to January 2008 received small incision non-phacoemulsification cataract extraction combined with IOL implantation under topical anesthesia,and the clinical effect was observed.·RESULTS:The effect of anesthesia was obvious in operation,the excellence rate was 94.7% and good rate was 5.3% and the total effective rate was 100.0%.There was no case who received anesthesia of behind the eyeball and around the eyeball because of pain.There were 65 eyes(57.5%)with naked vision 0.5 or above and 22 eyes(19.5%)with naked vision more than 0.8 in one day after operation.There were 85 eyes(75.2%)with naked vision 0.5 or above and 17 eyes(15.0%)with naked vision more than 0.8 in one day after operation.All of them were followed up for one month and no case was with decressed vision.There was one case(0.9%)with naked vision less than 0.5 because of diabetic retinopathy.There were 7 eyes(6.2%)with corneal endothelium edema,4 eyes(3.5%)with bulbi hypertonia,and all of symptom disappeared after dealing.·CONCLUSION:The effect of small incision non-phacoe-mulsification cataract extraction combined with IOL implantation under topical anesthesia is obvious and safe,so it is worth being used widely.·
