方法：对2010-06/2012-11期间经我院筛查适合手术的白内障患者1 800例1 800眼，实施免费白内障超声乳化及人工晶状体植入术，并主要对年龄相关性白内障的术后效果与并发症进行分析。

结果：手术患者中年龄相关性白内障为1 326眼(73.67%)； 年龄相关性白内障手术后第1d脱盲率达98.72%，脱残率达89.52%。术中并发症：后囊膜破裂32眼(2.41%)； 平衡液逆流7眼(0.53%)； 悬韧带完全断裂1眼(0.075%)，部分断裂5眼(0.38%)。术后并发症：角膜水肿103眼(7.77%)，轻度角膜水肿79眼(5.96%)，中重度角膜水肿24眼(1.81%)； 反应性葡萄膜炎6眼(0.45%)； 一过性高眼压9眼(0.68%)； 人工晶状体夹持3眼(0.23%)； 黄斑水肿6眼(0.45%)。未发生大泡性角膜炎、暴发性脉络膜上腔出血、感染性眼内炎等严重并发症。

结论：白内障超声乳化术在患有年龄相关性白内障的手术患者中疗效显著，超声乳化术手术时间短，创伤小，术后视力恢复快，并发症少，在白内障复明手术中优势明显。

METHODS: From June 2010 to November 2012, free cataract phacoemulsification and IOL implantation were performed for 1800 poor patients of cataract(1800 eyes), and the effects of the operation and complications of age-related cataract were analyzed.

RESULTS:A total of 1326 eyes(73.67%)of the operated eyes had age-related cataract. On the first day after the operation, vision was restored in 98.72% and vision was 0.3 or better in 89.52%. Intraoperative complications included posterior capsule rupture in 32 eyes(2.41%), equilibrium liquid reflux in 7 eyes(0.53%), complete rupture of suspensory ligament in 1 eye(0.075%), and partial rupture in 5 eyes(0.38%). Postoperative complications included corneal edema in 103 eyes(7.77%), mild corneal edema in 79 eyes(5.96%), moderate to severe corneal edema in 24 eyes(1.81%), reactive uveitis in 6 eyes(0.45%), transient high intraocular pressure in 9 eyes(0.68%), IOL clamp in 3 eyes(0.23%), and macular edema in 6 eyes(0.45%). Severe complications, such as bullous keratitis, explosive suprachoroidal hemorrhageor and endophthalmitis did not doccurred.

CONCLUSION: Ultrasonic phacoemulsification, offered free to poor patients of cataract in China, has various advantages, including remarkable effect, shorter operational time, minimal operational trauma, faster visual restoration and fewer complications.
