1. A method for irrigating an intracorneal channel within a cornea using a hand-held irrigation device comprising a cannula that includes (i) a shaft section having a first end, (ii) an arcuate section having a blunt tip, wherein an exterior surface of the arcuate section comprises a rough-surface region, and (iii) a lumen extending from the first end of the shaft section toward the blunt tip of the arcuate section, the lumen including an opening in the rough-surface region of the arcuate section, the method comprising the steps of:
accessing the intracorneal channel via a radial incision;
inserting a part of the rough-surface region of the arcuate section into the intracorneal channel;
moving the inserted part of the rough-surface region of the arcuate section within the intracorneal channel to detach a plurality of color pigments from a first wall of the intracorneal channel and a second wall of the intracorneal channel; and
injecting an irrigation fluid into the intracorneal channel through the opening, to flush the detached plurality of color pigments from the intracorneal channel.
