Surgery for glaucoma is a procedure in which a surgeon unblocks drainage angles of the eye or makes drainage channels in the eye to allow for eye fluid escape, or to treat glaucoma-related pain, notes WebMD. While some types of glaucoma surgeries focus on speeding up fluid drainage, others focus on preventing blockage of the drainage angle. Other procedures focus on lessening eye fluid production by destroying the ciliary body, which is a portion that is responsible for the fluid formation.

Glaucoma surgeries that facilitate fluid drainage include trabeculectomy, tube-shunt surgery, and laser sclerostomy, states WebMD. The procedures that focus on preventing drainage angle blockage include surgical iridectomy, which involves creating a drainage channel in the iris with a surgical cutting tool, and laser iridotomy in which a surgeon creates drainage channel in the iris by applying laser.
