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.

Sir,

Autologous serum has been used effectively to treat severe dry eye syndrome1 (DES) and persistent epithelial defects2 (PED). However, difficulty obtaining funding and delays in production often make it unfeasible for acute cases. The authors report on finger prick autologous blood (FAB)3 as an alternative treatment option.

Patients cleaned a finger with an alcohol steret. Next, they produced a drop of blood using a diabetic lancet and applied it to their lower fornix. They repeated this technique to apply FAB four times per day to each eye. A different finger was used for each eye to reduce any risk of cross-infection.
