Histopathologic correlative study of Kelman-style flexible anterior chamber intraocular lenses.

Three of 16 eyes in which Kelman flexible anterior chamber lenses were implanted were obtained for postmortem examination, and the lenses and globes were analyzed histopathologically. Thirteen additional lenses, removed surgically secondary to various complications, were studied by scanning electron microscopy. All of the lenses ere well finished and none showed evidence of degradation or cracking of the polymethylmethacrylate optics or foot plates. Some of the lenses showed deposition of inflammatory debris or erythrocytes, reflecting a clinical history of uveitis. In some cases, the problems seemed to be related to variations in surgical technique or improper sizing.
