Post Cataract Op - Black Spot on Iris?

I know 4 people who have had cataract surgery. All four now have a black long mark on their iris. Is this normal? I am about to have mine done this week, so if this is normal, is there any way of avoiding it?

Black Spot On Iris


Cataract surgery alone generally does not cause a spot on the iris.  What you are seeing may be a reflection off of the intra-ocular lens or a peripheral iridectomy used to treat glaucoma.
