Abstract
An ophthalmic cannula assembly may include a cannula having an outer cannula surface and an inner cylindrical bore. A hub adjoining a proximal end of the cannula may define a maximum outer hub diameter that is greater than an outer diameter of the cannula. An optical fiber may be attached to the outer cannula surface for at least a portion of a length of the cannula. A cover material may be in contact with the outer cannula surface, and may cover at least a portion of the optical fiber. A light diffuser may be disposed at a distal tip of the optical fiber.
