后房型人工晶状体脱位的研究现状

Review on the study of intraocular lens dislocation

人工晶状体脱位是白内障摘除联合后房型人工晶状体植入术后较为常见的并发症之一。手术中截囊不完全、撕囊不均、悬韧带和(或)后囊破裂、皮质残留、囊袋收缩、渗出膜及机化条带牵制、后发性白内障及外伤等因素均可导致植入的后房型人工晶状体脱位。目前针对后房型人工晶状体脱位,可采用单纯人工晶状体复位、囊袋张力环植入、前房型人工晶状体植入、悬吊式人工晶状体植入、人工晶状体取出以及玻璃体切割术等。

Dislocation of intraocular lens （IOL） is one complication of cataract extraction and posterior chamber IOL implantation. The reasons for IOL dislocation include incompletion of lens capsule cut, unevenness of capsulorhexis, break of zonules and/or posterior capsule, remain of lens cortex, capsule contraction, drag of exudate and organize strap, after cataract, trauma, etc. And the treatments for IOL dislocation include simple IOL reposition, capsular tension ring （CTR） implantation, anterior chamber IOL implantation, suspensory IOL implantation, IOL dislodgment, vitrectomy, etc.
