Histopathologic findings in a transsclerally sutured posterior chamber intraocular lens.
A 77-year-old woman had penetrating keratoplasty (PKP), removal of an anterior chamber intraocular lens (IOL), and implantation of a transsclerally sutured posterior chamber IOL for painful pseudophakic bullous keratopathy. Postoperatively, preexisting anterior synechias led to painful secondary angle-closure glaucoma and the eye was enucleated 8 months after the PKP. Light microscopy of the eye revealed that the haptics of the IOL were surrounded by a variably dense fibrous membrane consisting of connective tissue and fibroblasts. In some areas, the haptics had eroded into the superficial stroma of the ciliary body. Except for rare foreign-body giant cells, no inflammatory cells were present near the haptics. This case illustrates that haptics of transsclerally sutured posterior chamber IOLs may be stabilized by fibrous membranes and/or by erosion into the ciliary body relatively soon after implantation. This should be considered if surgical centration, removal, or exchange of such a lens is planned.
