The manuscript presents a review of published studies regarding the outcomes, causes, and complications of phakic intraocular lens (pIOLs) bilensectomy.All pIOLs will be explanted at some point, therefore is important to know the visual and refractive outcomes following bilensectomy.
There are few publications about the outcomes following pIOL bilensectomy; in all of them, cataract remains the main cause of bilensectomy. Other causes are endothelial cell density loss and pupil ovalization. The mean time between pIOL implantation and bilensectomy is longer in eyes implanted with an anterior chamber pIOL than in eyes implanted with a posterior chamber pIOL. There is a significant improvement in uncorrected and corrected distance visual acuity after bilensectomy. Some sight-threatening complications like retinal detachment and low endothelial cell density (ECD) after surgery have been reported. Current publications suggest that endothelial cell density loss is more frequent in eyes that underwent bilensectomy for an anterior chamber pIOL.
Good visual and refractive outcomes are achieved after bilensectomy, regular endothelial cell density measurements should be performed in all patients implanted with an anterior chamber pIOL to perform a safe bilensectomy.
本文回顾了已发表的关于有晶状体眼人工晶状体（pIOL）双襻切除术的结果、原因和并发症的研究。所有 pIOL 都将在某个时候被取出，因此了解双襻切除术后的视力和屈光结果非常重要。
关于 pIOL 双襻切除术后结果的出版物很少；在所有这些出版物中，白内障仍然是双襻切除术的主要原因。其他原因是内皮细胞密度丧失和瞳孔椭圆形化。与后房型 pIOL 植入相比，前房型 pIOL 植入后行双襻切除术的平均时间更长。双襻切除术后，未矫正和矫正远视力均有显著改善。术后报道了一些威胁视力的并发症，如视网膜脱离和低内皮细胞密度（ECD）。目前的出版物表明，对于因前房型 pIOL 而进行双襻切除术的眼睛，内皮细胞密度丧失更为常见。
双襻切除术后可获得良好的视力和屈光结果，对于所有植入前房型 pIOL 的患者，应定期进行内皮细胞密度测量，以确保安全的双襻切除术。
