AIM:To study the clinical effect of phacoemulsification and intraocular lens(IOL) implantation on uveitis complicated cataract. METHODS:Totally 20 cases (20 eyes) of uveitis complicated cataract underwent phacoemulsification and IOL implantation, with 3 eyes combined with peripheral iridectomy. RESULTS:Compared with preoperation, the visual acuity improved in 18 eyes (90%) at postoperative 2 weeks. The corrected visual acuity was better than 0.5 in 10 eyes (50%),0.3-0.5 in 5 eyes (25%),0.1-0.2 in 2 eyes (10%), less than 0.1 in 1 eye (5%),unchanged in 2 eyes (10%）. CONCLUSION:Although the surgery of phacoemulsification for treatment of uveitis complicated cataract is complex,the overall effect is good.
