Removed Intraocular Lenses: A Clinical and Histopathological Study

• Kang DH

Abstract

Twenty intraocular lenses removed after periods of use ranging from 2 months to 17 years were examined by scanning electron microscopy(SEM). The lenses were retrieved from three sites, anterior chamber, iris-fixed and posterior chamber. The reasons for removal and type of lens were compared to the pathological findings and length of wear. Scanning electron microscopy showed pigment containing epithelial cells, fibroblasts and macrophages on all three categories of lens. The pathological response was not site specific. The presence of these cells on the lens surface strongly suggests a foreign body reaction by the host to the intraocular lens regardless of the duration of implantation or type of intraocular lens.
