Corneal irrigation system and method of use

A corneal irrigation system for removing a color pigment from an annular intracorneal channel within a cornea, the system comprising:

• a barrel for holding an irrigation fluid, the barrel including a distal opening and a fluid port;
• a plunger configured to be inserted into the distal opening of the barrel and further configured to slide within the barrel;
• a hand-held device comprising
• a handle including a second lumen extending from a distal end of the handle to a proximal end of the handle, and
• a cannula including:
• i) a shaft section having a first end that is coupled to the handle's proximal end,
• ii) an arcuate section having a blunt tip, wherein an exterior surface of the arcuate section comprises a rough-surface region that encompasses the blunt tip, the rough surface region configured to (a) be moved along the intracorneal channel and (b) simultaneously scrub a first wall of the intracorneal channel and a second wall of the intracorneal channel, and
• iii) a first lumen coupled to the second lumen, the first lumen extending from the first end of the shaft section toward the blunt tip of the arcuate section, the first lumen including an opening in the rough-surface region of the arcuate section;
• and
• a flexible tube having a first end and a second end, the first end of the flexible tube configured for coupling the flexible tube to the fluid port of the barrel and the second end of the flexible tube configured for coupling the flexible tube to the second lumen at the handle's distal end.
