Some men who have a history of use of Tamsulosin (Flomax) are at risk for a condition called Intraoperative Floppy Iris Syndrome that can develop during otherwise routine cataract surgery. It is not fully understood why this condition develops or who is at risk for developing it. In this study the investigators will take pictures of the iris and iris blood vessels before cataract surgery. The investigators hope that the results of this study will provide a better understanding of how Intraoperative Floppy Iris Syndrome develops and give us a non-surgical way of figuring out who might develop this problem during surgery.
