Cocooning of an iris-fixated intraocular lens in a 3-year-old child after perforating injury: clinicopathologic correlation.

We present a 3-year-old patient who developed extensive noninflammatory fibrous membrane formation in the anterior chamber involving the present iris-fixated intraocular lens (IOL), with subsequent need for explantation. The child had had repair of a corneal injury, crystalline lens extraction and Artisan iris-claw IOL (Ophthec) implantation after a penetrating injury 2 months before. Histopathologic analyses were consistent with a retrocorneal membrane that originated from the corneal stroma and formed a "cocoon" membrane on the iris-claw IOL.
