Successful intraocular lens implantation: a histological and scanning electron microscopic study of four cases.

The histological findings in four globes obtained at autopsy from clinically uncomplicated cases with intraocular lens implants, one glass posterior chamber and three anterior chamber lenses consisting of two pupillary fixated and one "in-the-bag" fixated Binkhorst lens, are reported. Minimal changes could be detected in the tissues with which the implants were in contact. Scanning electron microscopy of the cornea in the three anterior chamber implants showed a loss of endothelial cells in the axial region of roughly 30-50%. There was marked vertical disparity in the loss. Scanning microscopy of the implants showed evidence of surface degradation of the nylon loops of all the anterior chamber implants.
