[Topical amniotic fluid: a potential new alternative for ocular surface diseases].

Amniotic fluid bathes the fetus during intrauterine life and is in permanent contact with the fetal ocular surface in this important period of development. It contains a series of growth factors that may have multiple effects on the wound healing process. These factors are thought to accelerate the recovery of corneal sensitivity and nerve regeneration after keratorefractive procedures, and also may control scar formation and balance the ocular surface after topical application.
