Ok. But that’s not what you said in your first post. You said the doctor had YOU make eye drops with your own blood, use them four times a day and keep them in the freezer. The way you presented it wasn’t possible or sanitary. Never mind the ridiculousness of you drawing your own blood and putting it in your eyes, if you keep blood in the freezer, it would be frozen, so you’d be thawing and refreezing the blood 4 times a day.
