The superior supporting footplate of the Tennant-Anchor anterior chamber lens can subluxate through a basal peripheral iridectomy. In each of the three cases reported herein, the implant migrated superiorly along the ciliary body pars plana. In two cases, the lens implant was stabilized by adhesions of the superior supporting footplate to the ciliary body. In the third case, lens movement (pseudophakodonesis) caused the inferior lens footplate to rub against the corneal endothelium, producing secondary iridocyclitis and cystoid macular edema which required intraocular lens removal and exchange. This complication may be prevented by performing a mid-peripheral iridectomy or iridotomy rather than a large basal iridectomy.
坦南特-安可前房晶状体的上方支撑脚板可通过周边基底虹膜切除术发生半脱位。在本文报道的三例病例中，植入物均沿睫状体平坦部向上移位。在两例病例中，晶状体植入物通过上方支撑脚板与睫状体的粘连而得以稳定。在第三例病例中，晶状体移动（人工晶状体震颤）导致下方晶状体脚板摩擦角膜内皮，引发继发性虹膜睫状体炎和黄斑囊样水肿，这需要取出并更换人工晶状体。通过施行周边中部虹膜切除术或虹膜切开术而非大型基底虹膜切除术，可预防这一并发症。
