Abstract

An apparatus includes a pad assembly, an injector assembly, an injector driver, and a fluid source. The pad assembly is sized and configured to be placed on a forehead of a patient. The injector assembly includes a body, a flexible cannula, and a needle. The body is configured to be removably secured to the pad assembly. The cannula is sized to be inserted through an incision in an eye of a patient. The needle is slidably disposed in the cannula. The injector driver is operable to drive the needle longitudinally relative to the flexible cannula. The fluid source assembly is in fluid communication with the needle.
