Intraocular Lens Opacification following Intracameral Injection of Recombinant Tissue Plasminogen Activator to Treat Inflammatory Membranes after Cataract Surgery

Figure 2

(a)–(d) Patient 2: (a) explanted IOL shows a band shaped configuration of fine white granular material in the central part of the optic. (b) Cross section through IOL shows positive granular staining with alizarin red. The granules are arranged linearly and diminish towards the periphery of the IOL optic (OM ×40). (c) The deposits are distributed below the surface of the IOL (OM ×5000, scanning electron microscopy). (d) Energy-dispersive X-ray spectrometry confirms the presence of calcium (Ca) and phosphate (P) in the deposits. Note that the spike for silicon (Si) is an artefact caused by a silicon wafer which was used for the analysis. (IOL: intraocular lens; OM: original magnification).
