[Human collagen IV lenses and epikeratoplasy in monkeys. Study of epithelial cicatrization].

Abstract

A previous study showed the good tolerance of the human type IV collagen lenses implanted by epikeratoplasty in 8 monkeys. It also showed type IV collagen is a good material for the reepithelialization. But we have been interested in the stability of the epithelial healing. The ultrastructural study found anchoring structures. However these were inconstant. So the authors try to understand better the mechanisms of this synthesis of the anchoring structures and describe the future ways of this experimental study.
