A 39-year-old woman with a history of high myopia underwent uneventful implantation of phakic posterior chamber implantable collamer lenses (ICLs) 6 years earlier in both eyes with a visual acuity of 20/20 bilaterally. The patient presented as an emergency with sudden decreased vision in her right eye after blunt trauma. Slit-lamp examination showed a partially dislocated ICL in the anterior chamber, associated with ocular hypertension. It was decided to treat her with topical ocular hypotensive agents and surgical repositioning of the ICL. There was a progressive loss of endothelial cells and decreased visual acuity. Descemet stripping automated endothelial keratoplasty was needed to correct the endothelial failure. This case presents a potential complication of the ICL several years after implantation, and should be considered in these types of procedures.
一名有高度近视病史的39岁女性，6年前双眼顺利植入有晶状体眼后房型可植入式胶原晶状体（ICL），双眼视力均为20/20。患者因钝挫伤后右眼视力突然下降而急诊就诊。裂隙灯检查显示前房内ICL部分脱位，伴有眼压升高。决定用局部降眼压药物治疗并对ICL进行手术复位。内皮细胞逐渐丢失，视力下降。需要进行Descemet膜剥除自动内皮角膜移植术来纠正内皮功能衰竭。该病例呈现出ICL植入数年之后的一种潜在并发症，在这类手术中应予以考虑。
