This exact question was answered yesterday.

I would like to know if the Yag laser worked. I have had it twice now ,and I see some improvement but I still have some cloudiness in that eye. Right after he did it, I had a large black floater that lasted for several hours but has left now.
However I have three very annoying floaters in the other eye that I had a retinal tear in. My Dr told me that he hoped they would fall below my vison line in time.I understand exactly how you feel, No one really has any answers that satisfy me,At least the Dr I am seeing now has compassion, The one who did my cataract surgery had no signs of being human.:O( That is why I left him and am now seeing a Dr at mayo clinic in Jacksonville, Fl.
It sounds like a vitreous floater which is pretty common after yag laser treatment. It should settle down in time, but there are no guarantees. Lots of floaters can ignored by the brain as well.
good luck. i know they can be difficult, but options to deal with them are very very limited, and controversial.
