Cataract Surgery With a Pre-Existing Filtering Bleb

Rachel G. Simpson, MD; and Roya Garakani, DO

Show Description +

In this episode, Rachel Simpson, MD, and Roya Garakani, DO, discuss a routine cataract surgery case that was complicated by an existing ischemic bleb from a previous filtering surgery. They review what to consider before surgery in these types of cases, including anterior chamber instability, loose zonules, and bleb-induced astigmatism. They describe their approach to this case and the selection of a toric IOL to provide a good refractive outcome.
