Are stents for hearts or eyes?

There are devices that can be placed in the eye at the same time as cataract surgery that can treat eye pressure. These devices are often used for patients with mild-moderate glaucoma and cataract at the same time. One of these devices is called the iStent, and I am quite a fan of it. The main reason that I like it so much is that it is in accordance with our primary medical dictum, primum non nocere. That is, first (and above all), do no harm. While the iStent is not as effective as we may like it to be, it doesn’t cause much harm. Certainly, there are small risks of some complications; however, it is one of the safest procedures that can be done to lower eye pressure (classic “glaucoma surgeries” are notorious for having post-operative issues).
