Abstract

An ophthalmic insertion tool includes a housing having a distal end and a proximal end, and a cannula attached to the distal end of the housing. The cannula includes a distal tip with at least one port in communication with a lumen extending through the cannula. The tool includes a retractable sheath coupled with the distal end of the housing. The retractable sheath is configured to move between a first position covering the distal tip of the cannula and a second position exposing the distal tip of the cannula. The tool includes at least one scleral marker integral with the housing. The at least one scleral marker is located adjacent the distal end of the housing, the proximal end of the housing, or both the distal end and the proximal end.
