Since then, however, the MIGS space has grown significantly with many options addressing the same outflow pathway. As such, it might be time to start talking about MIGS in terms of procedural categories. “The MIGS space has expanded throughout the years,” said Brian Francis, MD. “There are some novel mechanisms that are being introduced, but there are also a lot of procedures in the same space. I think it makes sense to talk about the mechanism of action rather than the name of the procedure itself.” As Robert Noecker, MD, put it, “we’re at critical mass” with multiple entries available in each space, so “it only makes sense to talk about these in categories now.” “It wasn’t as important before because there were only a couple of things to think and talk about and everyone was on the same page. Now many companies offer multiple strategies and operate in different parts of the MIGS spectrum. It’s important to do this to reduce confusion and help sort out the technologies,” Dr. Noecker said.
