Cytological factors relating to posterior capsule opacification following cataract surgery.

This paper discusses tissue culture experiments with human lens epithelial cells that demonstrate that cells from all parts of the anterior capsule have regenerative capacity, that the cells from younger patients proliferate more than those from older patients and that cells from cataractous lens retain their growth potential. Epithelial cells may be removed from the anterior capsule by EDTA in an infusion fluid and epithelial cells adhere more to PMMA than HEMA intraocular lenses. The clinical implications of these studies are discussed.
