Autologous Serum works very well for dry eye symptoms and eye redness. It is made under sterile conditions and usually lasts for about 3 months. Autologous Serum, though is expensive.
I am not sure I would recommend this for patients unless they cannot afford as Autologous Serum made in a sterile setting.
