I want know about bloodless surgery?

Bloodless medicine: so the idea behind bloodless medicine is, before your surgery you have your own blood drawn. About 3-4 pints before the operation. If you do need blood because of excess bleeding in the OR, the surgeon will use the blood they obtained prior to give back to you. If you had further bleeding, they will start you on IV iron therapy, and epogen (epoetin alfa) to stimulate blood production.

Cataract: Cataract surgeries are bloodless surgeries. But if you want to know about any particular ones, the list of bloodless surgeries may not be big. Surgeon try to limit the blood loss to very minimum.
