How can cataract surgery cause bleeding?

ANSWER

It's rare, but during surgery, blood vessels that supply the retina may start bleeding for no reason. A little bit of blood isn't a problem, but larger amounts could lead to loss of vision.

After surgery, blood may collect between the cornea and iris -- the colored part of your eye -- and block your vision. Eye drops may help, and you'll need to rest in bed with your head up.

If the blood doesn't drain or causes too much pressure in your eye, you may need surgery.
