The histopathologic findings of four eyes obtained postmortem with iris-sutured posterior chamber intraocular lenses (PC IOLs) are described. These IOLs were implanted as exchange procedures. In most instances, the loops were not situated in the ciliary sulcus but rather were suspended behind the iris and ciliary body. Therefore, the primary mechanism of fixation of iris-sutured PC IOLs appears to be the sutures themselves rather than adherence to the ciliary tissues. This report of four eyes is preliminary, but the pathologic analysis, showing few significant lesions attributable to the IOL, provides a reason for optimism for using this technique. A long-term clinical study comparing the results of sutured PC IOLs with those of anterior chamber IOLs (AC IOLs) used in secondary or exchange implantation, as well as collection and analysis of more pathologic specimens, should provide a more definitive answer as to the preferred procedure.
本文描述了4只死后获得的、植入虹膜缝合后房型人工晶状体(PC IOL)的眼睛的组织病理学发现。这些人工晶状体是作为置换手术植入的。在大多数情况下,袢并未位于睫状沟内,而是悬吊于虹膜和睫状体后方。因此,虹膜缝合PC IOL的主要固定机制似乎是缝线本身,而非与睫状组织的粘连。这4只眼睛的报告是初步的,但病理分析显示人工晶状体所致的显著病变较少,这为采用该技术带来了乐观的理由。一项比较缝合PC IOL与用于二期或置换植入的前房型人工晶状体(AC IOL)结果的长期临床研究,以及更多病理标本的收集和分析,应能就首选手术提供更明确的答案。
