Abstract: An apparatus includes a body, and anchoring feature, and a guide feature. The body is sized and configured to be positioned on an eye of a patient. The anchoring feature is configured to secure the body to the eye of the patient. The guide feature is configured to guide a cannula into a scleral incision formed in the eye of the patient along a path that is substantially tangential relative to the eye of the patient. The guide feature is sized and configured to allow the cannula to pivot laterally through a range of angular motion at the scleral incision.
