    "description": "A glaucoma operation that reopens the eye's own drainage channel. A hair-thin catheter is threaded around Schlemm's canal — the ring-shaped vessel at the edge of the iris that carries fluid out of the eye — and a thick gel is injected to stretch the channel open along its length so fluid can leave more freely and pressure inside the eye falls. In this version nothing is left behind once the catheter is withdrawn; the companion code covers the same surgery when a stent or tensioning suture stays in the canal to hold it open.",
