马方综合征(Marfan syndrome,MFS)是与晶状体异位有关的常见的全身性疾病，约50%~80%的MFS患者存在晶状体异位。该文报道一例21岁的男性患者，因患有MFS致双眼晶状体半脱位伴双眼并发性白内障，先后实施白内障摘除人工晶状体植入合并囊袋张力环悬吊固定术，术后保留低度近视，随访期间未发现眼压升高、人工晶状体严重移位及囊袋皱缩等并发症。

Marfan syndrome (MFS) is a common systemic disease associated with lens heterotopia, and about 50%~80% of Marfan patients have lens heterotopia. This article reports a case of a 21-year-old male patient who suffered from bilateral lens subluxation and concurrent cataract due to MFS, who underwent cataract extraction and IOL implantation with CTR suspension fixation was performed to preserve low-grade myopia after surger y. No complications such as increased intraocular pressure, intraocular lens severely displacement and capsular bag shrinkage were found during follow-up.
