We performed posterior chamber lens implantation (IOL) in three monkey eyes. All pseudophakic eyes developed a ring-shaped opacity, appearing on the IOL optics along the anterior capsule incision line. Transmission electron microscopic study revealed that the anterior capsule opacification was composed of proliferated cellular and extracellular components between the anterior capsule and the IOL optics. The proliferated cells looked like fibroblasts, but they were connected by desmosomes and covered by basal lamina. These histologic findings represented morphological features of epithelial cells, probably lens epithelial cells. Extracellular components consisted of collagen fibers, microfibrils, and basal lamina-like materials.

D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D002386	Cataract	Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence).

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
