An 84-year-old man presented with decreased visual acuity in his right eye for 2 days. In 1992, he had received cataract surgery with a nonhaptic, nonfolding intraocular lens with a nearly 8.5-mm diameter. Under the microscope, the intraocular lens could be seen covering the posterior pole (Figure). Perfluorocarbon was injected into the vitreous, and the intraocular lens was elevated carefully with a flute needle connected to a vitrectomy machine and removed in front of the surface of the perfluorocarbon. The intraocular lens was clamped into the anterior chamber by retinal tweezers and pulled out after the corneal limbal incision was enlarged. A new intraocular lens was suspended in a routine way. The patient’s visual acuity improved to 20/40 OD at 1 week postoperation. We report this case not only to show this rare intraocular lens, but also to show clinicians how to deal with the dislocation of such an intraocular lens with minimal disturbance of the fundus.
