To evaluate indications, clinic characteristics, and outcomes in a series of patients who underwent explantation of phakic intraocular lens (pIOL).
Retrospective case series of patients who underwent iris-claw pIOL explantation in our institution from 2018 to 2022. Indications for explantation and visual and refractive outcomes were analyzed.
Twenty-three eyes of 14 patients underwent pIOL explantation with a mean time to explantation of 11.7 ± 3.4 years. The mean age at explantation was 46.0 ± 3.9 years. Sixteen Artisan and seven Artiflex IOL were explanted. The main indication for explantation was endothelial cell loss ( = 14) and morphometric significant alterations of endothelial cells other than endothelial cell count decline ( = 5). The mean corrected vision after explantation was 0.4 ± 0.4 logMAR, and around 70% of intervened patients achieved visual acuity of at least 0.3 logMAR (0.5 in decimal scale).
In our group series, the main reason for the removal of pIOL was endothelial cell loss. This complication should be monitored and followed, so that early actions, namely IOL explantation, can be performed to avoid the development of deterioration requiring corneal transplantation. In fact, loss of follow-up, found in several cases for many years, continues to be a serious problem.
评估一系列接受有晶状体眼人工晶状体（pIOL）取出术患者的适应证、临床特征及手术结果。
对2018年至2022年在我院接受虹膜夹型pIOL取出术的患者进行回顾性病例系列研究。分析取出的适应证以及视觉和屈光结果。
14例患者的23只眼接受了pIOL取出术，平均取出时间为11.7±3.4年。取出时的平均年龄为46.0±3.9岁。取出了16枚Artisan和7枚Artiflex人工晶状体。取出的主要适应证是内皮细胞丢失（n = 14）以及除内皮细胞计数下降外内皮细胞的形态学显著改变（n = 5）。取出术后的平均矫正视力为0.4±0.4 logMAR，约70%的干预患者视力达到至少0.3 logMAR（小数视力表为0.5）。
在我们的系列研究中，取出pIOL的主要原因是内皮细胞丢失。应监测和随访这一并发症，以便能采取早期行动，即取出人工晶状体，以避免发展到需要角膜移植的恶化情况。事实上，多年来在几例病例中发现的失访问题仍然是一个严重问题。
