Postoperative localized opacification of the new MemoryLens design: analyses of an explant

We describe a different form of opacification of the new MemoryLens intraocular lens model CV232, leading to a decrease in visual acuity and requiring explantation. A well-circumscribed, centrally/paracentrally located opacification of the optic was observed, with the aspect of a small "lens inside the lens." Histochemical and surface analyses revealed the presence of calcified deposits within a void in the optic substance. This void was seen as a linear optic breach in analysis of an optic cylindrical block cut through the area of opacification, from a sagittal view. The origins of the optic void are unclear.
