Spontaneous posterior dislocation of an intraocular lens presenting as pupillary block glaucoma.

摘要

We describe spontaneous posterior dislocation of an in-the-bag, plate-haptic silicone intraocular lens (IOL) 1 year after neodymium:YAG laser posterior capsulotomy. The patient presented with an acutely painful eye associated with loss of vision. The initial cataract surgery was uneventful. Clinical findings at presentation were suggestive of pupillary block glaucoma attributable to vitreous herniation into the anterior chamber. The acute attack was broken after pupil dilation. The patient subsequently had removal of the dislocated IOL via a pars plana vitrectomy and implantation of an IOL in the ciliary sulcus.
