No, Eylea isn’t a steroid. Steroids, which may also be called corticosteroids, are medications that reduce inflammation (swelling). They may help ease swelling in your eye, but they don’t treat whatever is causing the swelling.
Eylea, on the other hand, is a type of drug called a vascular endothelial growth factor (VEGF) inhibitor. It reduces the swelling in your eye by treating the cause of the swelling. Eylea works by reducing leaking from blood vessels in the eye and stopping new blood vessels from growing.
