In patients with both cataract and glaucoma, the ophthalmologist may choose to treat both conditions in the same operative encounter. Combined cataract extraction, IOL implantation, and iStent insertion offers the patient visual rehabilitation, better control of glaucoma, and the benefit of not having to return to the OR for a second procedure. The iStent inject is a minimally invasive glaucoma surgery (MIGS) that bypasses the trabecular meshwork. It consists of a flange with a central lumen, a thorax that resides in the trabecular meshwork and a head that resides in Schlemm’s canal. The head contains a total of 4 outflow orifices. By avoiding a filtering procedure, one can also avoid the known serious complications associated with blebs, in exchange for decreased IOP-lowering.
