Calcification of a hydrophilic acrylic intraocular lens: clinicopathological report.
A 72-year-old man who had phacoemulsification with implantation of an Akreos Adapt Advanced Optics (AO) IOL in the left eye complained of blurring vision 4 months postoperatively. Multiple fine white granules were found within the IOL. Intraocular lens exchange was performed at 7 months, and the explanted IOL was sent for histopathological analysis. Diffuse fine white granules were seen within the explanted IOL material just beneath the surface; they were stained positive by alizarin red and the von Kossa method. Scanning electron microscopy confirmed the presence of calcium deposits in the IOL material. Blood and aqueous were drawn from the patient for biochemical analysis, and the results were normal. We believe this is the first clinicopathological report of calcification of the Akreos Adapt AO IOL.
