I had been taking Flomax (Tamsulosin) for several years.
My Ophthalmologist knew about this and knew the risk associated with cataract surgery after taking Flomax. Floppy Iris syndrome, in which the iris attempts to protrude through the surgical incision.
He had a lot of experience and felt he knew when there was a risk and when not. Unfortunately, in my case, he was wrong. The end result is that I lost a pie wedge shaped portion of my iris.
I am currently trying a tinted contact lens to block the additional light, which is uncomfortable. I am now trying to determine if any, and how much damage to my eye is caused by the additional light, if I don't use the lens.
