Numerous techniques of pupilloplasty have been described to restore iris anatomy. However limitations arise in phakic eyes due to the propensity for crystalline lens damage. We describe a novel technique for pupilloplasty in phakic eyes, wherein a plate haptic intraocular lens or phakic intraocular lens provides a scaffold and protects the anterior crystalline lens from subsequent surgical manoeuvres. The technique is demonstrated in a 24-year-old male who presented four months following blunt trauma to his left eye, with complaints of glare and difficulty in near activities secondary to traumatic mydriasis. The use of an intraocular lens scaffold allowed successful pupilloplasty without iatrogenic tissue trauma or subsequent crystalline lens opacification up to one-year follow-up. Our technique affords a safe pupillary repair without damage to the clear crystalline lens or the need for a concomitant lens extraction.
已经描述了许多瞳孔成形术技术来恢复虹膜解剖结构。然而,由于晶状体损伤的倾向,在有晶状体眼会出现局限性。我们描述了一种用于有晶状体眼瞳孔成形术的新方法,其中板状虹膜接触镜或有晶状体眼人工晶状体提供了一个支架,并保护前晶状体不受随后的手术操作的影响。该技术在一名 24 岁男性中进行了演示,该男性左眼在四个月前受到钝器伤后出现眩光和近视力活动困难,原因是外伤性散瞳。使用人工晶状体支架可以成功进行瞳孔成形术,而不会造成医源性组织损伤或随后的晶状体混浊,直至一年的随访。我们的技术提供了一种安全的瞳孔修复方法,不会对透明晶状体造成损伤,也不需要同时进行晶状体摘除。
