摘要:
A transparent illuminated infusion cannula is described. The cannula includes an optical fiber to provide light to illuminate an area within an eye; a hose to transport fluid; a protective sheath; an incision cannula to incise the sclera of the eye and a transparent cannula within the incision cannula. The transparent cannula is positioned coaxially with the optical fiber and a space between a distal end of the optical fiber and proximal end of the transparent cannula allows fluid to flow around the distal end of the optical fiber, into the transparent cannula, and into a sclera aperture. A flow cross-sectional area is substantially constant within the hose, cannula, and interface between the hose, cannula and optical fiber.
