Bovine Basic Fibroblast Growth Factor eye drops, commonly known as Bevosol, are designed to promote mitosis of corneal cells and to promote the growth of corneal cells to restore the cornea. It is mainly for trauma or inflammation, or other causes of corneal epithelial defects, the corneal epithelium can be restored within 3-4 days with this drop, but it does not work for inflammatory infections. Because fibroblast growth factor only promotes cell growth, not antibiotic drops, therefore, infectious keratoconjunctivitis, we should wait for inflammation control before using bovine basic fibroblast growth factor drops to consolidate the late recovery effect.
