方法：收集本院2007-05/2011-12期间白内障伴晶状体半脱位(由外伤、Marfan氏综合征引起)的患者24例28眼，其中4例8眼为Marfan氏综合征引起的晶状体大范围脱位，其余均为外伤引起的脱位，均行超声乳化白内障吸出术或前段玻璃体切除并Ⅰ期植入Artisan虹膜夹型人工晶状体。术后观察视力、角膜内皮细胞计数、人工晶状体位置和术后并发症。随访时间为6mo。

结果：与术前比较，术后最佳矫正视力均有不同程度的提高，术后视力0.1～者20 眼，0.5～1.0者8眼， 随访1～6mo，没有出现人工晶状体移位、虹膜炎症、虹膜萎缩及角膜失代偿等并发症。

结论：白内障伴晶状体大范围脱位手术难度大，但只要术者有丰富的临床经验和高超娴熟的技能，仍可行超声乳化白内障吸出术或前段玻璃体切除并Ⅰ期Artisan虹膜夹型人工晶状体植入术并取得较好的手术效果。

METHODS: Twenty-four hospital patients(28 eyes)of cataract with lens subluxation by trauma(20 patients, 20 eyes)and Marfan's syndrome(4 patients, 8 eyes)during May 2007 to December 2011 were selected. All of them underwent phacoemulsification or an anterior vitrectomy and Artisan iris-clip IOL implantation at stage Ⅰ. Postoperative visual acuity, corneal endothelial cell count, intraocular lens position and postoperative complications were observed. Follow-up time was 6mo.

RESULTS:Compared with the preoperative, postoperative best corrected visual acuity improved to varying degrees, visual acuity of 0.1-0.5 was in 20 eyes, 0.5-1.0 in 8 eyes. After followed up 1-6mo, no artificial lens shift, iris inflammation, iris atrophy and corneal decompensation and other complications were observed.

CONCLUSION: Cataract surgery with a wide range of lens dislocation is difficult, but as long as surgeons who have a wealth of clinical experience and superb skills, still can carry out phacoemulsification surgery or anterior vitrectomy and Artisan iris-clip IOL implantation and obtain a better outcome.
