AIM:To investigate the clinical effect of small incision extracapsular cataract extraction and intraocular lens implantation. ·METHODS:From the April 2007 to December 2008,312 cases who underwent the small incision extracapsular cataract extraction and intraocular lens implantation analyzed retrospectively. ·RESULTS:Postoperative visual acuity increased signifi-cantly,≥ 0.05 were in 307 cases,off blindness rate accounted for 98.4%; ≥ 0.3 were in 285 cases,and off disability rate accounted for 91.3%. Intraoperative and postoperative complications:posterior capsule rupture 4 eyes accounted for 1.3%; corneal edema 75 eyes account-ed for 24.0%; iris damage 2 eyes accounted for 0.6%; temporary high intraocular pressure 5 eyes accounted for 1.6%; pupil mild deformity 6 eyes accounted for 1.9%; intraocular lens gripping 2 eyes accounted for 0.6%; postoperative uveitis 12 eyes accounted for 3.8%; withnot artificial lens implanted 5 eyes accounted for 1.6%; The average corneal astigmatism was 1.53±1.32 in the posto-perative day 7,and no serious complications occurred. ·CONCLUSION:Small incision cataract extraction and intraocular lens implantation has a significant effect and fewer complications,and it is safety and easy surgery,especially in primary hospital for the prevention of blindness.
