报告１２例（１２眼）行白内障囊外摘除联合后房型人工晶体（ＰＣ－ＩＯＬ）植入后发生人工晶体脱位或半脱位患者，其中瞳孔夹持７眼，“日落”综合征２眼，脱位于玻璃体、“东西”综合征和“日出”综合征各１眼。１２眼中，瞳孔夹持１眼经保守治疗成功；２眼保守治疗未复位，但病情稳定；９眼行手术治疗，其中５眼由原切口直接取出人工晶体，１眼行联合玻璃体手术取出人工晶体，３眼瞳孔夹持行手术复位。认为瞳孔夹持早期以手术复位好，对白内障囊外摘除加ＰＣ－ＩＯＬ植入术后出现ＩＯＬ脱位或半脱位而视力尚可，且尚无并发症时，应尽早处理，以防发生严重的并发症。
Reported 12 patients (12 eyes) underwent extracapsular cataract extraction combined with posterior chamber intraocular lens (PC-IOL) implantation occurred after intraocular lens dislocation or subluxation, including pupil holding 7 eyes, sunset syndrome 2 eyes, off Located in the vitreous, “things” syndrome and “sunrise” syndrome in 1 eye. 12 eyes, the pupil holding a successful conservative treatment; 2 conservative treatment did not reset, but the disease was stable; 9 eyes underwent surgical treatment, of which 5 were removed directly from the original incision artificial lens, a line of vitreous surgery removed intraocular lens , 3 pupil holding row surgery reduction. That the early pupillary clamp surgery to restore a good, extracapsular cataract extraction plus PC-IOL implantation after IOL dislocation or subluxation and visual acuity is acceptable, and no complications, should be dealt with as soon as possible in case of serious complication.
