Pars plana vitrectomy in the management of subluxed and posteriorly dislocated intraocular lenses.
The results of pars plana vitreous microsurgery in a series of nine patients with subluxed or posteriorly dislocated intraocular lenses (IOL) are described. Two posterior chamber intraocular lenses were repositioned in the ciliary sulcus anterior to the zonular ring. One posteriorly dislocated anterior chamber IOL was retrieved from the vitreous gel and repositioned into the anterior chamber angle. In three cases, stable repositioning of the dislocated posterior chamber IOL could not be achieved and the lens was exchanged by way of a limbal incision for an appropriate anterior chamber IOL. In three cases, and anterior chamber IOL subluxed into a large basal iridectomy was successfully repositioned using similar instrumentation.
