Some recent studies have shown that pirfenidone (PFD) has favorable results in the healing process of the cornea. However, PFD in solution exhibits short half-life after topical application, and in this context, a liquid crystal nanoparticle system containing PFD (PFD-LCNPs) was developed. The nanoparticles were characterized by transmission electron microscopy, atomic force microscopy, small angle X-ray diffraction and polarized light microscopy.
