Hi ….
Serum Tears or Autologous eye drops are compounded tears for severe dry eyes. They are made from your own blood. Red blood cells and clotting factors are removed, leaving behind blood serum. This is diluted with a sterile, preservative free solution to produce a tear substitute that is unique to the patient, and contains many important growth factors and nutrients normally found in healthy tears. Since blood and tear shave an almost identical salinity and pH, there is no issue of burning or stinging upon instillation. Because they are non-preserved, the drops are stored in the freezer until you need them. They aren’t covered by insurance so not cheap but they help SO much.
I go to OCB and I see a dry eye specialist. Cequa are eye drops that work better than Restasis. I use them 2x/day. Try Ophthalmic Consultants of Boston and ask specifically for a dry eye specialist.
