title: The case of the disappearing and reappearing intraocular lens.
abstract: A 75-year-old woman who underwent implantation of an anterior-chamber intraocular lens was noted to have the lens disappear from the anterior chamber four days after surgery and reappear on the eleventh postoperative day. Ultrasound documented the position of the lens as apparently lying posterior to the sclera and anterior to the ciliary body. Extrusion through a cyclodialysis cleft superonasally was the apparent mechanism of exit and reentry. Pseudophakic dislocation is becoming increasingly common.
